My skills at sharpening could definately use some improvement that I think could be made from practice. How much sense does it make to buy a couple of the $1-$3 knives available on ebay purely for the purpose of practicing sharpening them? One of my thoughts is that the steel may be so "cheap" or "soft" that I'll never get a good edge on them no matter how good my technique may be and thus won't be able to gauge my results. I've heard of practicing on hacksaw blades but that seems that it would be too far away from the feel of an actual knife. Has anybody bought "practice" knives and how did that work out? Any other ideas?
