    One can tell a good vs a bad samurai during battle by the length of time past between each movements or blows with or without their katanas.
    As a rule of thumb, each movements made requires a "pause" of 2 to 3 seconds.
    But the truly great masters were able to make pauses lasting up to 35 seconds (or more!!) following each moves, made possible only by a strictly disciplined mind, decades of training and practice and astounding concentration!!!
    In a duel, unlike in the west where a fight could be done in an instant, the samurai's fight could take 2 to 3 hours!
    But to witness 2 truly great masters duelling with their katanas, one would have to book at least a week off work as the duel could last up to an incredible 6 full days and nights!!! Thus leaving all spectators at the edges of their seat, filled with anticipation to know whom will be victorious in this battle of life and death. This was truly a dangerous era to live in...

      Seen some period movies depicting what your saying - the full flags and regalia of two houses taking the field to witness the duel. Not many of many seem to draw to that correct battle display.

    It’s amazing how to cultures who Appear very close in nature such as the Chinese and Japanese are so different! The Chinese do not care about copyrights or in Frenchman and make everything as cheap and chunky as they can and sell it to the world for pennies in the Japanese make their own products the best that tcould be made and are worth a ment to the world

      Today's steel is far from inferior. The folding process was a way to work out impurities in the steel and not exclusive to Japan.

    Please read this and let me know what you think .

    I was born on a Thursday. Which is Thorsday aka Joves day aka Jupiter's day aka Zeus . All these gods are the same God but different names from different cultures and so is Amon Ra , the Egyptian sun god considered to be the same .
    My name has a few meanings, one being that it means son of jove descended from Jupiter . Also means youthful , which is appropriate too as I am a leap year , so I only get a birthday every 4 years , sadly I still age like anyone else though lol .
    So I was born on the 29th February 1968 at house number 29 . I was born at home.
    The leap year comes from the Julian calendar which was set up just over 2000 years ago in order to compensate for the fact that a day isn't exactly 24 hours . It's around a minute ish out . Over a year it adds up to 6 hours and a full leap day over 4 years , which is my birthday . My parents knew none of this when I was born or when they named me , it was pure coincidence .
    It's a bit like lucifer the light bearer who I think in some cultures stole the light or lightening bolt or fire , from God. Different versions in different cultures but all basically the same theme .
    A minute of day light from each day stolen .Julius Ceasar was the one who established the Julian calendar , with knowledge given to him by Sosoginese of Alexandria, Cleo Patras astronomer, whilst he was having a relationship with her . The Egyptians, I believe, were the first to discover and use this knowledge to help them get the timing right for planting their crops each year .
    Julius Ceasar was also The Flamen Dialys, The High Preist to Jupiter, before he became the famous leader he was. He also claimed that he was a descendant of the Julian family of Troy, aka The Gens Julia, who claim their root ancestors to be Aphrodite aka Venus aka The morning star lol aka Lucifer and Prince Anchises of Troy who was king Priam of Troys first cousin . So this is also where my name comes from .
    3 days before I was born Jupiter , which takes 12earth years to orbit the sun , passing through all 11 constellations as it does , entered into my mother's sign of Leo , where it stayed until mid June I believe, the 6th month lol . Coincidence ? Lol .
    12 signs not 11 , sorry for the typing error .
    My birthday also falls 66days and 6 hours after Christmas day, the day we celebrate the birth of Christ.
    U am a true believer in Jesus but I'm far from perfect , rarely go to church , have faults , feel lust and attraction to beautiful women. A regular guy . I am known amongst my friends and respected as being a nice decent too honest too nice guy for my own good lol . Which has caused me so much strife in my life . Arrogant fools take goodness and kindness for weakness and stupidity . People who know me well consider me to be honest honourable and decent . Which has got me into a lot if fights in life , people try and pick on me mistaking me for a weak fool lol . I hate fighting it scares me , I consider that a healthy quality and a big part of my self defence and survival instincts . Their underestimation of me has always been my greatest weapon in defence , in over 60 street fights that I neither wanted or started , always tried to walk away and avoid , which just encouraged them even more and only served to convince them, wrongly lol , that I was easy meat lol .
    I hate hurting people but I hate being hurt or letting people hurt the people I live too . I have stopped to help strangers a few times when I see them getting set upon unfairly .
    You may find this short video interesting when considering the leap year calendar and the 66 days and 6 hours after Christmas day to a leap year.
    There is quite a lot more that involves Saturn , which I believe was the original holiday celebrated by the Romans on the 25th December . My daughter who by coincidence has a name that means child of light. Was conceived just after my 28th birthday, which was the first time since I was born
    As a leap year only falls on any one day of the week once every 28 years . She was born 5 weeks plus a few days after my 29th birthday .
    We all have what is called a Saturn Return .
    It is where Saturn , returns to the sign it was in when you were born . Like a Saturn birthday . We always used to say on someone's birthday . Many happy returns of the day. Well a Saturn year is 29.5 earth years long . And our Saturn return is 2.5 earth years long. As it spends around 2.5 earth years passing through each of the 12 constellations or as some say the 12 disciples of the sun . I got with my daughter's mom 2 weeks before my 28th so I was still 27 , my daughter was conceived in June 1996 , first time my leap year birthday fell on a Thursday the day I was born on since I was born . The 6th month lol , she was born early April 1997 which makes her an Aries, The Horned Ram of Amun and also the sign for the Mars God of war I believe.
    Our Saturn return period starts aged 27 and lasts to 29.5 years of age and is considered to be a great time of maturing .
    My mother's name was Miriam , a lovely kind hearted lady . Miriam was the name of Moses sister along with their other sibling Aaron. These three siblings lead the Hebrew slaves out of Egyptian bondage to the promised land , I think that's right lol . Egypt was the place the Sphinx is found and I have read that the Sphinx is a representation of Leo the lion and constellation and is supposed to align with the constellation of Leo once every galactic year of around 25 thousand years. The great year of the precession.
    I was born when Saturn was in Aries , the horned ram of Amun . And it was back in Aries again when my daughter was conceived and born. And her name was given to her by her big sister without us knowing it meant child of light.
    Aaron Moses and Miriam all siblings with great leadership and prophecy abilitys. They belonged to The Benjamite tribe that escaped The Pharoahs enslavement .
    In my dad's side Benjamin is a big name that was held by my grandad , his first born who was my uncle Ben . Grandad fought in ww1 uncle Ben fought in Ww2 , uncle Ben was a sergeant major in the army for 25 years. And then theirs my big brother Ben , both he and I were born at number 29 . My mom said she could hear the family cheering England downstairs on 30th July 1966 in the world cup whilst she was giving birth lol.
    I've had to defend myself over 60 times in unwanted street fights and never lost .
    I did get jumped by 3 bouncers , one was the British professional boxing champ a couple of years later . This happened Christmas day 2000 , even though I got a beating , it wasn't one on one , they took me by suprise and still never knocked me out or floored me .
    When Troy fell , apparently, according to myth , the refugees split into two , one group with Prince Aeneaus eventually landed in Italy and their descendants founded Rome , Romulus and Remus. And the other group with Brutus of Troy according to myth, landed in Britain and founded the first Kings Of Britain and the tale of Kong Arthur is said to be linked to them in some way .
    There is a lot of weird instances that have happened throughout my life and continue popping up here and there . A few are recorded officially too , on the internet in the form of coroner's reports and newspaper reports .
    I'm not saying any of this actually means anything but I find it fascinating .
    I just thought that it would be pretty awesome to make my own sword . Seens how I can link all of this to ancient times warriors great leaders myths and God's who all lived and died by the sword and are such a big part of our history and film industry etc .
    I want to learn to make my own swords and make one a nice one and maybe call it Excalibur lol . Draw that mythical sword right out of "The Stone" age myth and into modern day reality lol . What do you reckon lol .
    Think I missed a bit out , my daughter was conceived just after my 28th birthday in June, and born around 5 months after my 29th birthday . First time my birthday fell on a Thursday aka Thorsday since I was born , at house number 29 , on the 29th .

      Some katana have bo-hi (fullers) some have one sided, two sided, or more than one fuller on a side. Others have none. They are a method to change the balance of the blade. When polished, they can reveal more grain pattern in the steel. They affect the sound the sword makes when swinging.
