Thanks Jason

I do believe the tanto tips do what they claim. However since 95% of the game I hunt is deer and turkey with an occasional hog now and then I have never really had to  oppurtunity to test the therory. I had used ACE 160 Standards for years with a very sharp and pointed tip and never lost an animal due to the point sticking in bone. However the last 4 years I have started using the Grizzly 160's not so much for the tanto tip but really like the cutting action of the single bevel heads.

However I am sure if I hunted bigger game I would be more concerned about not sticking in bone.

I've rounded (and sharpened) the tips on my Zwickey's and STOS two-bade heads for years.  Also knock the needle point off my Wensel Wodsmans.  Doesn't take much in either case.  Just a little strengthens the point and keeps it from turning over on bone hits. I don't like the tanto points on most single bevel heads.  Concept is fine, they're often just too large.

I completely curled the tip of a Zwickey Delta when I hit a VERY large bull elk in his scapula from 18 yards with my long bow. My arrow ricocheted almost all of the way back to me. After that I filed chisel tips on my Zwickey's and have since changed to a single bevel with tanto tip Cutthroat broadhead.
