First off, good question. I have seen many discussions both on-line and offline about this very topic.
Folding steel while forging blades is an old method used to improve the quality of steel in ways such as, purity, and the spread of carbon and to remove any voids within the steel. This was discovered in Japan and widely used soon after since the average quality of Japanese steel at that time was pretty lousy this helped improve the quality in blades greatly.
spring steel is steel which is all ready of a high quality. thus, no folding is needed. when it comes to the question which steel is best all I can tell you is: Neither.
Quality wise, if you have folded the steel enough and in the right way, the quality should be the same as of that of spring steel. The real issue when it comes to the quality of a blade is the craftsmanship As long as you make the core soft (low -carbon) and the shell hard (high carbon) and rid the steel of impurities and any voids you should have a top quality katana as long as the rest of the crafts are done right ( clay tempering etc).
Personally I would prefer a folded steel katana since this is a bit more traditional than the spring steel ones, and also because I know the amount of work and craftsmanship required is greater. But when it comes down to it, the important choice is not that of the steel (as long as it is high quality in the end) but that of the forge and the smith. here's a hint to all of you looking for swords to buy:
Always discuss your wants with the forge or preferably the smith before ordering. and remember that in the end, It is not what you use that determines the outcome of battle, but how you learn to use "it".
Hope this answer could shed some light into this question. I do not remember the smith that is said to have discovered the folding layer technique first ' s name, but You should be able to learn it without any special exertion's

A spear. Some people will tell you a katana, but the katana has little practical value in mass combat.
it depends on what style you use the katana is to be taken as an extension of the body if you are training with a katana use a wooden one then use the real one. good luck
TIMMAY
Mainly a katana.
Nowhere. Stop believing movies are real. Folding modern steel doesn't make it better, anyway. 16th-century steel sucked and it was folded to make it suck less.
I believe it's the legendary katana, the daichri (spelling is off)
you can find a tonto or strait katana online or thu special order but if it is not folded steel is is a poser on will not perform.
