Double Defense action makes the B.M.F. Black Tri-Edged Baton Dagger a beast of a self-defense weapon in your hand. Use it as a hard-hitting impact baton or twist it open to access the tri-edged spear blade. It has a 10 1/4” cast 2Cr13 stainless steel tri-edged blade with a matte grey finish and a sharp penetrating point. The shaft, which also houses the blade, is a heavy-duty steel tube with a black oxide finish and a textured and ridged grip. The tube can be screwed onto the end of the blade handle to increase the length of it. The 16” overall tri-edged baton dagger can be carried in its tough, nylon belt sheath with reinforced stitching and Velcro closure.
