I recently made a knife out of a Nichlson farrier rasp. Flat ground it to about 1mm. Heat treated, and procceded to finish grind it. In my hast I ground the primary bevel to pretty much zero so I went with it. I then sharpened it, and it is scary sharp. At least for me. The sharpest knife I've ever made. Question is: In the vast expereince found here, is grinding the primary bevel to almost zero pretty much relegating that knife to kitchen duty or can a man produce a field use knife with this geometry? (assuming that all other factors are in order, known steel, proper heat treat etc.) I've yet to really use this knife, although it just slides through paper (which I asume is because there is no real shoulder creating resistance), so I can't say that its tough enough to really do some work. I rolled the edge on a brass rod...seems good.
