My STOS in action. Look to the left and you will see the arrow buried to the nock quartering away in my 1,650 pound bison. I still have that same head, we removed it from bone when gutting the beast, swiped it with a carbide sharpener and it cut hair. I have taken two deer with it since and retired it to my trophy room with the bison mount. A great head, thank God you guys are carrying it!
