my first purchase was an Ontario gen II sp50 as a chopper and now i dont have any idea for last 2 knives ( boot knife and common slicer). From what i read on forum a slicer should be a 440c SS because of the corrosion resistance but im curious about 14C28N zero tolerance models, i want to know if this 14c is more rust resistant than 440c and if it holds an edge as well. For the boot knife ( can be used as a neck knife too) im thinking at zero tolerance 0150 boot knife since its s30v and very corrosive resistance. Does anybody know the blade thickness of 0150? I couldnt find it anywhere
