Mighty generous of you. This is also a great way for people that don't own slip joints to get introduced to this side of the knife hobby.
My favorite maker is a toss up between Darrel Ralph and Pohan Leu. I can go either way. Both listen to my input and make a knife around my specifications. In the end, I have a true custom that I either designed entirely or had enough input to make the knife truly unique, a one of a kind.
