My snap on rep has replaced my diagonal side cutters many times over the years due to both chipped cutters and worn pivots.Probably up to reps discretion. On the other hand I have several Mac tools 3/8 drive impact sockets that have rounded off and will not break. Metal is too soft.Dealer said to hammer a ball bearing in to the socket to crack them. All that did was distort them into the abuse category and so not warranty.Had a route screw up and this happened at the shop a few months ago.RJ
