Over my 63 years and probably 120K miles of cycling, I have come across various forms of "hardware road kill," most often small hand tools (Snap On sockets, anyone?

). I just add them to my collection or give them to my sons to round out their respective tool collections. I participate in various bicycle and small appliance "fix it" clinics, and if I have extra copies of a given tool, I'll lend them to other fixers and/or customers, with no expectation of return. I guess that earns me some compensating karma.
