I think every serious knife user and collector should own a few knives in INFI. It is the ultimate combat knife steel. There are those who will settle for nothing less, but I am not one of them. But then I am not Rambo. Honestly, 1095, 5160, SR77, 52-100 and a few others if properly heat treated and ground serve me well. Being a big chopper lover, I just had to have the FBM and FFBM. I have a couple of ASH-1s, too. And the Sarsquatch is a great medium size chopper. Those SFNOs look good, too, but I don't really need one. The DFLE and SOD LE will do anything I could want a big knife to do, and at a reasonable price. After seeing the final DF test pics, I'm not worried at all that I might break either one of them.
