But the Stryker's a tanto, which I still believe holds no cutting advantages over a knife with a "normal" belly. It's also has a remarkably thin point (though it's darn pretty), so I doubt its tip is any tougher than the Starmate's. I think given the heat-treatment we've seen from these two companies, the 440V holds every advantage over ATS-34. Much tougher, finer grain so sharper, and with at least as good edge holding. It as nearly twice the carbon content, after all.
But both steels are excellent on the larger scale, as are the knives in question. I haven't held a Starmate yet, but the ergonomics on the Stryker are really something special. I'd recommend if possible that you get both in your hand and make the decision that way. One or the other is bound to grab your heart in some way. Hopefully not both
