A non-stamped sword made recently is likely superior to the vast majority of what was used in combat historically due to improvements in metallurgy. Not all modern made swords are stamped replicas. Many are at the very least as combat ready as any sword carried into the fight at Agincourt or Crecy.
modern "stamped" swords are most often 440 stainless steel...which are definitely NOT combat ready...
a good video showing the toughness of stainless steel.
http://www.youtube.com/watch?v=2kFgeZtkAb8you are very right though...most modern hand made swords are better then the originals.
the Tiger Katana I had was folded....for aesthetics only....the steel used was far better then the original Katana's.
a easy way to tell a good sword form a cheapO....
does it rust?
Carbon steel rusts and needs to be oiled....stainless steel is very rust resistant, so needs no oiling.
thats not to say every carbon steel sword is combat ready....
ok here is a story...Saxman seems to know what he is talking about....he can tell me if I am lieing or not.
I bought a Katana many years ago...nice spring steel....
I was young and dumb and foolishly tried to chop a log in half....
the tang bent right up and ruined the sword...I got pissed and smashed the flat part of the sword against a tree...basically wrapping it around the tree into a "U" shape....
I threw it down.....the very next morning I went to get it....and that friggen sword was straight....the tang was still bent all up and no good...but that blade was straight...and only if you held it up to the light at an angle could you see a warp in the blade.
see that blade itself was combat ready...but who ever made it..used what is called a "rat tailed tang" very weak.....making it a non combat ready sword....
fixing it would be as simple as cutting off that crappy tang...and moving the Tsuka up onto the wide blade....then it would have been combat ready.
