You've tapped into my "secret desire". I looked high and low for someone producing a truly custom barlow. The closest I got was with WhiteWing(?)knives. They had something close, but not quite what I was looking for. So I am setting aside my fixed blades, and am setting about to make my own--my way.
It really won't be for sale, as I want to make two and give them to each one of my sons. But, here is what I am planning. Barlow design with a lockback. Hopefully, stag, if not, then probably a imitation MOP, nickle bolsters (with my name in the bolsters, single blade (maybe two bladed) of 01 tool steel. Going to install some stainless steel shim washers between the blade and the bolsters to make the blade glide open! Those barlows really fit the hand right. I was thinking of a blade design of a kind of modified persian. Oh well, just waiting for materials to show up now.-Dan
