Iron Will Broadheads were designed for maximum penetration on elk. Our .062" thick A2 steel blades retain extremely sharp edges through hide, bone, and tissue keeping the cutting force low and maximizing penetration. Unlike most broadheads where sales are driven by whitetail hunters, a majority of the people who bought our broadheads last year were hunting elk. If you killed an elk with Iron Will broadheads, please post a picture; we would love to see the results. I'll add a few also and here is one from co-founder Eric Whiting.
