So when I got into knives there were really only two high performance stain resistant steels...154cm and D2. Old fashioned steels like 1095, O1, 52100, etc. were better performers, but you had to take care of them which I never minded. Fast forward many years and there are a plethora of high end knife steels that promise everything. Is there still a place for the old stuff? Is the only benefit the lower price?
