I prefer blade C with the following mods:
1) Some kind of wood or G10 scales should replace the Micarta. For me at least, Micarta--even bead-blasted canvas Micarta--is just too slippery, especially for a fighter.
2) For me, I'd prefer either VG-10 stainless, D-2 semi-stainless, or O-1 non-stainless over anything in the ATS-34, -55, or 154-CM class--I've had far too many problems with rust with those three types of steels. O-1 can be hard-chromed, which I'd gladly do; D-2 seems to do well, especially REKAT's D-2E; and VG-10 is given plenty of joy by people whose opinions I respect.
