Factually ESEE doesn't build knives there for not a manufacturer, Rowen builds there's and other companies knives under contract for ESEE , they own a brand of knives. I guess that's true for many manufacturers. Spyderco has almost all there manufacturing subbed out, except those few built in Colorado.
It seems that many brand owners developed an profession in some form of knife use be it military, well-known adventurers or survival expert and had knives built for them.
To my understanding few were actually knife makers by trade to start.
