Because I have a curious nature, or maybe just because I'm an idiot, I tasted two knives, one stainless Frost's mora (sorry, the steel number escapes me at the moment), and one 1095. The 1095 definitely had a metallic taste, the stainless barely any taste at all. So based on this highly unscientific and somewhat ludricous test I can see where some people might taste it on food; I bet it would get noticed more on acidic fruits or meat than on, say bread.
The original poster mentioned Parkerizing, does anyone know how it's done the right way, and/or you could get a similar finish in the home shop?
What about browning like muzzleloading guys use? How durable is that? It can look very nice on traditional knives and tomahawks.
