I thought the newer tip design went back further than that.The STOS I had,I bought at least 3 years ago and they had an excellent,tanto tip.A big selling point for me was the Stos had a very true ferrule and a precise and centered tip.I have never mounted glue on broadheads before where all of them spun true with no tweaking.The STOS did.If talking about the newer tip design,I wouldn't mess with it either,unless you wanted to hone it with a very fine stone.If you get that tip off center,it will be impossible to tell if your head is spinning true.I like to check the spin after a hit or miss on an animal to make sure everything is OK before it goes back into service.Of it's type,I think the STOS is one of the very best.
