Sam Brown Button Stud

A very old method of carrying a large sheathed knife, like a Bowie. The brass or steel stud is attached to the front of the sheath, near the top. The sheath is then pushed down behind the belt, with the stud resting on the top edge. Wear the knife vertically, or slant it at any angle you choose, for a comfortable fit. Works best when worn on your opposite hip, for a cross-draw.
