The Japanese have a proud tradition of skill at cutlery making. I've never used a Junglee knife, but a quick look at their online catalog shows them using AUS-6, AUS-10, and AtS-34 steels. AUS-6 and AUS-10 are Japanese steels roughly equivilant to our 440A and 440C steels, but have had a bit of Vanadium added to the matrix to improve grain structure(toughness) and edge holding. Never used either steel, although I just bought a Kershaw Vapor the other day, which uses AUS-6, but had to return it because its a right-handed knife only. I"ve used a lot of ATS-34, although I"ve switched to the original American manufactured 154CM in recent years. ATS-34 is the Japanese equivilant to it. I still use a lot of it(154CM); makes a great knife. Just based on the steels used, and the Japanese rep for quality cutlery, can't see where you could go wrong with one, as far as the steel goes. Can't say that I"m overly thrilled with their designs, but to each his/her own on that aspect.
