This thread presents and documents a series of blades made from a special sheet of Russian titanium alloy. After some experimentation, I've concluded that this complex ti alloy is a unique gem. 5Al 2Mo 4.5V 1Cr 0.7Fe, a Russian grade called BT23. Russians are skilled titanium experts. Ironically, in the 1960's even the titanium needed to build the SR71 Blackbird spy plane, which was made almost entirely of titanium alloy, had to be smuggled into the U.S. through a secret CIA program, to spy on the Soviets from whence it came. About 90% of all raw titanium ingots come from Russia. From there, the huge ingots are sent around the world to a handful of titanium smelters that further refine the titanium and alloy it with other elements. The vast majority of ti alloy is all-purpose 6al4v. Much of what's left is one of 4 grades of CP (commercially pure) titanium, unalloyed. What's left is turned into various high-alloy titanium stock for special uses, and a tiny fraction of that becomes Mad Science Forge blades!
