I???m not good with detentions i guess. I???ve never seen suck a wide punch. Wow. Well made and all if you need a brass punch the size of a small hotdog, but I bought it to drift out a 10/22 front sight and ended up spending way more time on it than I needed to. If I could have localized the pressure, it would have come right out. I ended up putting an ice pack on it to shrink the metal and it finally came out. It was fine for putting the new fiber optic sight in. Still, brass marks on more places than needed, but hey, they come off. That???s the idea, right? Anyway, well made punch. Not what I was looking for.
