I have a set of Mayhew roll pin punches that I have had for about 25 years. I have used them in overhauling transmissions, both standard and automatic, differentials, and now they are regulated to pretty much gunsmithing work. I broke the smallest one once many years ago and it was replaced free of charge. A good punch should never bend. If it has enough force put on it it should be hard enough to break long before it ever bends.
