SAMS-3BR is a longer sheath for knives with longer blades up to about 6". The sheath is about 9” deep, and will accept blades up to about 1” wide. I’d allow about 3” of depth for the handle, so it should work for knives with a 6” blade. The sheath is sewn with a welt, glued and stitched. The belt loop is securely riveted, and will take belts up to about 2 3/4" in width.
