This was not the first or only time one of us had lost or broken blades with them. And we were aware it could be in the animal some where, the thing is its like a needle in a hay stack, and many times you are not going to find it. If we were to keep using them we joked and said will have to carry metal detectors with us to check for blades every time. These and American broad heads are the only two heads we have had brake blades in an animal. And I am talking out of a lot of heads we have tried. There is a pretty good group of us that shoot different heads every year, so we get a lot more info, then just shooting a couple animals a year, And we have had many broad heads stick in bone, a glancing hit on the side of bone, thru bones, pass thru and bounce off rocks, feeder legs, trees and not lost blades, so I wont except a head that may or may not loose blades in and animal. There are to many good heads out to have to worry about it.
