RE: A really good knife.....
I watched my processor skin and quarter a deer with one knife and he did it all in a matter of a couple minutes or less. Of course he was wearing a sharpening steel rod hanging from his belt. Every few cuts he professionally ran the knife over the steel(took a few seconds) and you could shave with it. Man, I wish I could do that.
I really love my Gerber knives(American made) but they seem to dull a little sooner than I'd like. Of course it doesn't take much to put a nice edge back on them too.
