Michael, dealers usually contact the maker from what I know of the system. You may be able to talk to them and send them pictures or samples to generate some interest. Understand that dealers are looking for makers that are in current demand or are on the rise. There's not much business sense in them carrying a knife that noone knows or aren't seeking out (not saying noone knows you,) or is very similar to something they already have in stock. Make your knives, sell them and get that "buzz" going about Michael and they'll come to you. Usually at that point you really don't need them unless you just don't have time to market the knives yourself. The last consideration, it's been mentioned already, is it worth the 20-25% cut in revenue to have a dealer sell your knives? You're going to have to make 25% more knives to stay profitable.
From personal experience, lots and lots of sales isn't always the greatest thing in the world. You're going to die making 40 of the same knife. I've been on that road, it's hell for the artist. I'd rather make a little bit on a knife that I really enjoyed than to make a lot on something that I hated every stinking minute I forged, ground and finished.
Make MICHAEL'S knives, treat customers as if you're a clingy, insecure girlfriend, give them more than they expect and you really won't worry about sales.
Just my experience over the years.
