I was just doing some roof redo so I broke out my old AJC hammer other wise known as the mangler. It was a roofing hammer with a cutting blade opposite the head. It was impossibble to use without cutting yourself. You could be as careful as possible and you’d still cut yourself. Notice there is no blade in the hammer. I haven’t used it in years and haven’t used it with a blade in twice that long. Anybody else ever used one?
