Not to hi-jack this thread, but what are some good files to use? (I figure ya'll filers answering this thread have much more experience than me in this) I'm using nicholson's now, but feel like I've noticed a decline in performance from when I started making knives and now (Only a year+, there). I don't know if the move to Brazil is the reason, but I feel like I shouldn't have to buy a new 8+ dollar file every 2 knives if I'm only using them (a flat file) to clean up grinds and another file (half round) for finger grooves/etc). I don't care if I gotta pay 20 bucks a file or something, as long as it'll last appreciably (to = extra costs) longer.
