So, I'm looking for some advise on my Snap-On wrenches. I have a set of 3/8"-1" Snap-On wrenches from the late 70s that were my dads, They are badly worn and slip most of the time along with pitting on some of them and sanding marks on others, I contacted Snap-On about warrantying them and I'd have to send them in. Should I keep them do to the sentimental value or trade them in?
