shaun muzzy has changed hands and is now owned by same company that owns Rage and others. I used them years ago though and they worked great. missed a buck low and one went into a dead blown down tree. unscrewed the arrow from the stuck head, gently kicked it loose. spun fine, so i put it back on the arrow and then shot a doe and a red fox with it. i did swap out the blades after hitting the blow down though.
