Thread: .22 extraction issue

A simple turn of the tool forces the metal back into position. I used to have one but lent it to a friend some 40 years ago. He ran off with my girlfriend and tool and has since passed away. I couldn't find it at the tidyup after the funeral .

jeez who needs enemies with mates like that
