    • Speeder84XL
      Speeder84XL Month ago

      @The Forge Master Yes it is there, but way attenuated compared to "realistic" levels, because of his shitty microphone setup (which is quite obvious, given how faint the sounds was from the cans and can openers as well)

    • The Forge Master

      It's definitely there, the thud is just a little later than expected, at 6:02. It sounds like it falls on a sleeping bag or something.

    • Alexander Kupke
      Alexander Kupke Month ago

      @Speeder84XL Yeah, there is a whole science to it. No wonder "sound engineer" can be learned here in Germany as a university degree, or as sound technician in a 3-4 year apprenticeship. (The university part has some more theory while the apprenticeship of course is more hands one. I would mind neither doing the job, as both are usually highly skilled.) And then there are even specialties if you are studying movie arts, where you can delve into those specialized realms as well.
      And while I know some through reading and doing, I would put myself at best on a lower amateur level. Also I am less in videography than still photography. And neither was part of my computer engineering studies, although, working with telephony systems, I get into the nastyness of microphones and speakers in form of head sets more often than I like.

    • Speeder84XL
      Speeder84XL Month ago

      ​@Alexander Kupke It's different if you intend to do some sort of a mix that can't be done from one spot to get all sounds you want. But for filming, the best viewing/listening experience is usually to have the microphone close to where you would have you are ears if standing at camera position (perceived position actually - so, if a telephoto lens is used, the mic should ideally be closer than the camera).
      Best setup is in most cases, is to use 2 omnidirectional microphones in stereo with 34-37 cm between
      (that will give a sound very close to "binarual recording" without the need for a complicated dummy head setup. Also the greater spacing, compared to typical ear distance, will give better stereo perception when played back thru speakers, without sacrifice much of the listening experience thru headphones).
      Directional mics could be used in some cases - but those have a very poor low frequency response that makes them quite useless as high quality camera mics.
      The specifications for such mics, often shows they have a linear response all the way down to 20 Hz, but that's (due to the their acoustic and physical properties) usually only valid for close range recording at a certain distance (often not more than 60 cm from the sound source). Any closer than that it will have too much bass (which most studio people are well aware of. For example pod casters like to use it, to make their voice more "bassy", 🙃). But, further away, the bass is attenuated by quite a lot instead (which makes them poor camera microphones).

    13:33 - these can openers have internal mechanics that will give out far quicker than the lever on a standard can opener. My parents have stripped four of them already, meanwhile the can opener from my childhood sits in the drawer unused because my mother lacks the hand-strength to lever it. However, it IS the one that comes out for tuna fish sandwiches as the newer style of can opener does not lend itself well to the straining of can contents by pressing the cut (and prewashed) lid down and into the can to press out the tuna water/oil.

      @Me Here Not being able to eat alliums or tomatoes, I understand the challenge. That having been said, it wouldn't be that difficult to make a vegan meal plan with no wheat, nuts, or legumes - legumes being the most difficult to replace and also the reason why I still use my non-safety can opener. (As well as canned tuna, chicken, etc for the family.)

      I just fold the lid a bit across the center line, then it is smaller than the can along one dimension and no chance of the edge cutting your hand when squeezing the juice out.

      @Jennifer Nykanen Vegan diets are also hellaciously allergy unfriendly. I’d like to see a vegan create a meal plan that doesn't contain any kind of legume, nut, or wheat. They can't.

    • Jennifer Nykanen

      @Don Robertson This is the reason fish farms exist and tuna companies work so hard to use dolphin safe fishing practices. You're also not considering that canned tuna is the cheapest low fat protein source that millions of poor families depend on. Yes, vegetarian and vegan diets are a thing but they are often cost prohibitive and require supplementation to maintain health. That combo puts them out of reach for the poor. I can appreciate your compassion for the animals but it would serve you well to remember that humans are also animals and also deserving of that same compassion.

    as an older person I had a hard time with traditional can openers, so I tried the side (seam) cutting can opener. it is easer on my wrist and hands, cuts clean and with little effort. I find it to be very effective. This is coming from a mechanical designer with over 40 years experience. I highly recommend this for older people, or people with medical issues.

  • MrZedblade
    MrZedblade Month ago +6

    I've had one since the 90s and it still works fine. It opens every can I ever tried. My favorite part of owning it is watching other people who aren't aware of this type of can opener try to use it. The 25 seconds of ensuing chaos and confusion is fun every time.

    My example of amazing improvements since I was a kid is the new design of scaffold connectors, replacing the split pin and toggle with a post and locking bar design. Vast improvement. The old design would get jammed up with dirt or paint and soon require a hammer to move. The new design can be fished on from several feet down the diagonal cross rod.

    Now I expect a video on cans. From the hard soldered ones, that could be quite dangerous if done improperly, through the war year ones, to the modern ones with liners that essentially eliminate problems with botulism. And all the rabbit holes to square cans, flat cans, integrated openings, whether key, pop top, etc, to the self heating cans for military, and survival use. Easily another video or two in there.

    Now on a video about can openers, I think there are three methods worth mentioning:
    1. taking a regular roundblade opener (like in 3:28) and turn it horizontally, letting the blade run on the outside of the can and the counterwheel on the inside of the lid. That pops the head off of the can which admittedly leaves a sharp edge on the top of the cylinder, but it's a good alternative when the regular way does not give you enough grip. also helps with situations like 9:37
    2. the repetitive punctuation method with the can opener tool of a swiss army knife
    3. no tools: simply bending the can back and forth at half the height of the can until it becomes weak and brakes in half

    I can still remember my first time using one of these. It was at a restaurant I worked at. They had a mounted can opener on the table back by the sink, like it's a whole thing that clamps down and was screwed into the table. I was told to get some tomato puree, big can, size if my head. I am using this thing and feel like I'm not cutting anything the whole time, there's a knife on the bottom of the can opener like old ones and is intended for opening juices. I literally just stabbed the can open with that thing, probably the most jagged and unsafe can opening you will ever see, all because it didn't feel like it was cutting lol. Felt really dumb when they showed me how it worked lol. Everytime I saw that can in the walk in for the next week I saw evidence of me just going full ape.

    I used to have a "side-cutter" that still had two handles that you had to close together to make it start cutting - same as a top-cutter. It did not have the automatic clamping that yours has. Why is that better than yours? Two words...LEFT HANDERS. Because mine was completely ambidextrous - it opens the can identically whether you clamp the handles together on the left or the right side of the can - and whether you turn the handle clockwise or counter-clockwise. Sadly, it did eventually wear out - and I have yet to find a replacement.

    We've had one of these for years! It's actually a clamp-style like traditional can openers, but it cuts the seam rather than the interior of the lid. It also has a tiny grabber for the lid that's near-useless.

    I find it interesting, that the most common, in my experience, can opener wasn't even mentioned. A metal plate, with a hooked hole, and a sharkfin style blade. Opens cans, leaves nice, sharp lids. :)

    • Paxmax
      Paxmax Month ago

      @Omer Magen Aaah! Ok, so it is the "German can opener"! 😂 The plow part, the upper part of the spade, responsible for "the opening" isn't even sharp! So, basically it just pushes the metal to the sides... it does not cut or slit... nope, just mushes the tin and some zinc plating rubs off from the cans rust proof inner layer and form clumps of zinc, zinc dusting, zinc goo along the gouge the spade/plow leaves behind! The plow isn't even asymetrical to tend to stay near edge of can, no no, it can sometime take a heading more inward towards can center! But, it stays usually within about 1-5mm of can edge. Geez! The much simpler "swedish" (nordic?) opener is dangerous/prone to stab you if you rush it... which you always do because it only opens 3-4 mm per full stroke so it gets tedious. Ramming the German spade thru the lid definitely takes some effort and is not exactly confortable to hammer with a bare hand (if you do proper work with your hands daily its no problem, but I doubt many more than 10-15% of women would be able to cope with it without more tools).

    • Paxmax
      Paxmax 3 months ago +1

      Opens cans and hands in any demands! 😂 I found a worse one (or I actually need the instructions). The german opener: it has a vertical "V" pointed spade you need to ram through the lid from top. That spade is on a swiveling plate riveted to the handle. The handle has a series of small agressive shark fin tooth in a radius that gets traction on the outside of the rim. Then you drag the spade/swivel plate behind the handle when it feeds forward. Like a (dull) plow it works its way thru/around the lid while the handle bites into can outer rim. I hope there is a smarter way to get the spade through than the brute force i use 😂 technically i do not know if my opener is infact "the german can opener", it was the only one available to buy in the village store.

    Got one of those as a kid and the thing I remember is it had trouble with cans that weren't completely round. If there was a dent, then it would have trouble. It also didn't last very long before it broke. I think the mechanism that pulls the drive wheel in can wear out quickly, at least with the one we had. The traditional double wheel is much more reliable of getting the job done. Hopefully they have improved over the last few decades.

    Interesting thing, I seem to encounter mostly the pullopen type things here these days but I couldn't find my can opener a few months ago and still haven't gotten my own after borrowing one from my neighbour briefly to open the can on that day. I think I'll try one of these contraptions first to see how I like it, they aren't that expensive and also a bit more compact in the kitchen drawer.

    When I was a teenager, the lawnmower my parents owned had a self propelling feature which didn't work. This made the lawnmower a heavy push mower. The need for a replacement wasn't very high for my parents despite my complaints. This one worked just fine. When I moved out, however, they promptly bought a riding mover.

      What happens when the rider’s transmission goes out? Then you’ll have a really really heavy push mower?
      But seriously, a self propelled mower in good shape is very easy to deal with after training half your life with the extra weight of a failing self propelled. I once used my neighbor lady’s mower, a normal (gas) push mower and it felt so light and free rolling compared to my dad’s with worn down tires that wouldn’t engage the metal drive things.

    The tapered top of the "chunky soup can" allows nesting when they are stacked on the shelf. I learned this when trying to stock shelves of cans that were the same diameter on top and bottom.

      what surprises me most is that his can is slimmer at the top. I've only ever seen it done at the bottom, with the rim practically as wide as the can itself, just so that it fits inside the other side.

      Perhaps it's a Europe/America thing, but I've only ever seen cans with the taper on the bottom. I normally open the bottom of cans because it's easier to get the contents out if it's something like baked beans or a chunky soup, which means tapered and ring-pull cans go in the cupboard upside down.

    When I moved out of my parent's house and in with friends, I went from using a classic can opener to a "safety" can opener. For ten years I took for granted that when I open a can, the lid won't fall into the food and have to be fished out, and can be used to re-seal the can for refrigeration lasting at least a couple of days.
    Then I helped my mom make enchiladas back at home and used a classic can opener again.
    This video has motivated me. I'm going to inventory what kind of can openers everyone in my family use, and if they don't have a "safety" style one, they're getting one as a gift this year.

    This fits oddly well with the side discussion:

    1. Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works.
    2. Anything that’s invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it.
    3. Anything invented after you’re thirty-five is against the natural order of things."

    Both my wife and I have horror stories based on opened cans. Mine having happened because a can wasn't completely open, so I now always fully open them. Her's caused by a jagged can lid, so she always leaves it attached. It's been a struggle until this video came along. Thank you sir.

    2-3 years ago, I was upset about the jagged sharp edges ordinary can openers made. I searched many stores near me for different types of can opener. and what I found was this type that looks sooo different comparing to other typical type models, and it was more expensive and aesthetically more attractive to me. Curiosity made me to purchase it and try it out.
    It didn't take me too long to learn how to use it. I actually figured it out in less than 1 minutes. I immediately decided this is my favorite can opener for its perfect performance, which tooke me time to think about the mechanism it works on.

    My parents got a can opener similar to that one when I was growing up. It was touted as a "safety can opener" since it left a rounded edge on the lid. It had a "squeezing" mechanism like a normal can opening to bring the teeny cutting wheel into contact with the can (instead of the simple rotation grabbing the can like yours). I wonder if that was a change made to make it seem more familiar to people used to the Danger Can Openers.
    In other news, Toxic Midwestern-ness is a hilarious concept to me as a Nebraskan Millennial. The heat pump conversation is VERY familiar when discussing technology that "I don't need to bother with it, I tried it already and it was bad".

    The can opener with the angled blade wheel can be used to remove the lid completely. Hold the Opener with the turning grip upside. Grab the left side of the lid and turn from the top. Make sure the teethed wheel grabs the inside of the can seal. Never had sharp edges i thought this was a myth.

    I bought one of these can openers after watching this. My mom told me about a can opener she had that also cut into the side of the can instead of the top. It took the whole top off the can, but it left a sharp edge on the can. It cut the entire seam off.

  • Brandon Keever
    Brandon Keever 4 months ago +297

    My father opens cans using the "traditional" double-cog opener, however does it backwards: the cut is along the outside (cutting through the label rather than the lid / holding the rotating handle facing up instead of sideways). This solves a couple of problems, the whole thing comes off so it's easy to get food out, and the lid can't fall in. However, it takes a bit more effort to cut, and still leaves sharp edges. It's a good compromise however!

    • pandorafalters
      pandorafalters 4 months ago

      @Shuken Flash They are.
      My parents had a couple of can openers from the late '70s that were strong, solid, and reliable all through my childhood. They did, eventually, get a bit dodgy - dirty, dried-out grease on the axles, grunge on the insides of the blade and drive gear where you can't really clean them, etc.. So one day while they were out I took the can openers apart, cleaned them up thoroughly, reassembled them with new grease, and put them back in the drawer.
      About a week later I went to open a can and couldn't find either one. They'd come home with a new can opener and thrown the old ones away.
      Ever since they've needed a replacement can opener about every other year. This despite barely using them because they got an electric can opener a few months later - because the new manual one was already crap.

    • Madis002
      Madis002 4 months ago +2

      Came to the comments looking for this.
      Cutting from the side, not the top, basically eliminates the lid falling in and the annoying lip problems outright. Then it's a tossup between the sharp needles that might or might not be there vs the sharp edge you know to avoid. I personally prefer the latter, but probably not strongly enough to go buy a new can opener if I already had the "improved" one. I guess the new design gets a bonus point for the removed lid being somewhat still usable as a lid, but I personally do not care about that. Most of the time there is nothing left over and if there is I can figure something out.
      I like how thorough Alec is and hope he will see the above comment, try it out, have his mind blown and do a follow-up video on this. The 5 minute monologue in the end would have quite a different taste to it if he had been aware of this technique, I think.

      My current can opener is specifically designed to open them that way, you physically can't have the cutting wheel on the inside and make it work. Confused the hell out of me for a few seconds until I realised the cutter went on the outside.
      While it does leave the top of the can sharp I guess no sharp outer edge on the lid so you can lift it without fear of adding extra red sauce to the contents ain't too bad.

      @Shuken Flash I realise that because I’ve been using the “new” as a kid. I’ve been using the old openers wrong for a couple of decades.

I’ve never even thought to cut directly into the top and it really does explain why my can openers have been falling apart and subject to natural selection lmao

    My mom bought one of these back in the 90s when we visited Hong Kong. For me as a kid, it blew my mind. I didn't know it was invented in the 1980s!
    That can opener she bought was the only one of this kind we ever had, for many years. While at first I messed up some cans with it because I didn't know how to use it, I ended up figuring it out pretty quickly, and I used it regularly when living on my own in college. We don't have it anymore, because sometime in the last decade the cutting blade got dulled to the point where it just wouldn't really open cans effectively anymore. But we have yet to buy a replacement of this same type, which has always disappointed me.
    I fully agree with you that this is a superior design. It eliminates sharp edges, and I also love being able to put the lid back on the can and stick it in the fridge. I would love to get one of these for my next can opener (lol these things take a while to get used thoroughly...and now I'm thinking about how I've been planning for years to replace my car with a hybrid or EV except for the fact that my current car still has usable life in it).
    One thing I didn't see you address was some apparent "glue" between the lid and the can that sometimes shows up in the cans I open. I don't know whether it's actual glue or just food residue that's gotten stuck in the pressed portion and dried up, but for some reason there's sometimes a little bit of rubbery-looking stuff between the lid and the can when I open it with this style of opener. But it's always on the outside of the can so it's not really an issue for me.

    9:00 When I got a "safety" can opener for the restaurant I work at, my main reason for doing so was that the cooks could get a spatula in the cans to get more product out of the cans without the burrs left by traditional can openers slicing up the spatulas. A can opened with a safety opener is far less likely to damage a rubber spatula and cause physical contamination concerns.

      It seems like there ought to be a stapler that uses a roll of wire, that cuts the wire and forms it in a single action that also presses it through the paper and into the crimping die.

About a year ago, I could not find my Swiss Army knife for can opening, and had to figure out this can opener, poked around for couple of minutes, and exactly as described: felt like I was not making any progress at all. And then the lid came off in the cleanest way possible, that was mind blowing experience.

    Thanks for the revelation! The safety can opener is something I've never seen. Shall be buying at least one soon. But a couple of refinements to it would help greatly:
    1) Give it a longer turning lever to reduce the force required to use it.
    2) Adjust the cutting head geometry so that it can be used left-handed as well as right-handed. 10% of people are left-handed, and quite a few others have a weak or missing right hand.
    That's it for the safety can opener. For those who choose to read this further, about can openers in general, the following are some related points raised by the video.
    A useful tip: Attach a small Neodymium magnet to the tip of a conventional can opener, to allow the opener to lift off the cut lid from a steel can. No more fishing around in the top of the can when you don't stop cutting soon enough. It also lifts any small metal fragments which (rarely) drop into the contents. I've used magnets glued onto openers since about 1980. Why don't manufacturers add a small magnet, or magnetise the can opener itself? It's a simple and low-cost improvement.
    You're using the wheeled can opener backwards. I've never seen them turned that way before. Might try it.
    Another useful tip: The wheeled opener can also be used to cut around the side of most cans, removing the lid with no sharp edges, and allowing easy removal of all contents. The downside is that the top of the can now has a sharp edge.
    I've almost given up trying to use ring-pull cans. Most of the rings break off, sometimes leaving me injured, and a partially opened can which then needs opening with a pair of pliers. (I once cut myself badly when a fish can ring pull failed. That required a visit to the hospital and 15 stitches, including repairing a severed artery.) Not ideal. So I almost always use a can opener instead of the ring pull. If the can has turned-in top and bottom edges along with a ring pull, I simply don't buy the product. That said, some cans do have well-designed ring pulls.
    As for his hair, that's his choice, and I can live with that. If not, then I wouldn't be watching the video. Most of us have no right to tell anyone to change their preferences. Suffice it to say that, in certain walks of life, and in current times, hair like that can attract the wrong kind of person, if you're not looking for men.

When I come across one I struggle to use it lol. The one downside I've found with them is when I'm opening a food I need to drain. I use the lid to drain the food, and I can't do that with the way this safety can opener cuts the top.

    I found a lever action version of this style that has been great for older family members who have trouble turning the knob on the older style.

    I just need to say that I'm at awe at how good and tight your scripts are nowadays. Great choice of words and pace. One of my favourite TheXvid channels!

    have you ever tried using the "normal" can opener with the turn wheel parallel to the top and the sharp bit piercing the side of the can?
    you will get a very similar result with no lip and no lit falling on your (kid's) ravioli. =)

    I have a opener similar to that but it also has small jaws that let you grab the lid. You never have to touch any metal. Been using it well over 10+ years.
