Tuskers are made from spring steel. I have been shooting them for a few years along with Silver flames, Ace, and many other brands. My top choice Tusker is the Aztec. These are very tough and strong. I took an Elk in the spine with one, burried it to the shaft in solid bone. Had to use Vice grips to get it out and it was still just fine.
I have shot them thru several moose bones with no ill efects. For small game like grouse they are also very good and these ones get some serious rock hits and come out on top.
I think that you will find that any Hill style long nose head like the Concord is not known for keeping the tip as well as conventional designs. {See the Asby reports on long nose heads.}
Nothing is indestructible, however with the choices I have to shoot the tuskers are one of the heads I use very often.
If you bent a broadhead of any design on a foam target, you need to pull out the lost steel points in it.
They are not pretty, or sharp when you buy them but they are tough.
We need to remember these are broadheads , like all other brands, meant to shoot thru flesh and small bones like ribs.
My pick from Tusker is the Aztec, folowed by the
Delta on the higher performing bows and the little Spirit in the Selfbows and lower poundage bows.
