The Benchcrafted Tail Vise is indeed a wagon vise, meaning it uses a traveling dog block trapped within the top. The term wagon vise did not derive from our use of a handwheel, as in “wagon wheel” but rather as a translation of the French term describing this general style of vise. It is also a "tail" vise since it’s mounted on the "tail end" of the bench. Others call it an "end vise". Hey, we had to pick something!
