There are only a couple of folks that I let borrow tools - had too many in the past either not come back without a few reminders, broken or something other then what I lent out. The guy across the street borrowed a metric 14mm socket a few years(6-8?) ago - then returned it broken. I asked when I could expect the replacement S-K. We haven't spoken since then as it got "noisy" and over a 6 buck tool. Then there's my buddy who returns a borrowed tool with a 4 pack of Guinness
