The discuission actually started with a guy who started by making kit knives and now uses kits with some handmade components and said he sells them, rountinely, for $500-$800. I charged $175 for this knife:
I feel like that is a very reasonable price for the knife. He said I was undercutting full time makers, whose prices are still in the 1980's and who are struggling to make ends meet.
Anyway, I basically look at what's out there in similar materials and construction and go from there. My points were this:
1)95% of my work is done with hand tools. That means VERY slow going, which means it takes a lot more time to make a knife. I can make $450 an hour if I really try and my office is really humming. So, knifemaking is a hobby. I usually trade, or I sell to save money for equipment and materials. I can't charge $2500 for a knife that took me a few hours to make just because I am slow at what I do.
2) I got my start by making kit knives, too. My first was a Rob Simonich Cetan Tanto kit. It cost $40 and it was an ATS-34 blade ground by Rob. I got rob's pin material, instructions and Micarta, too. So, literally, with the exception of the quality of the finish, my finished knife was the same in almost every way as one of Rob's. I would never have been able to sell mine for what Rob sold his for because it's still a different maker and that's where a lot of the value comes from.
