STOS broadheads

[Wudstix]

Looks like the tip of a Ribtek.

I know I've put this picture up before, but it's of Doug Chase looking at a STOS that he single beveled with a tanto tip.  I think he got them without any grind to start with.  This part of the arrow was sticking out the far side of an Oz buff, out of a 70# DAS.  Both of his buff had the arrow sticking out the far side, and they did go through some ribs.
