When I was vey young, my father was a concrete contractor and when i went to a job site the workers would let me straighten the form nails, probably to keep me occupied. Eventually they explained to me that even if I got the nail perfectly straight, if they tried to reuse it it would bend again in the same location. The skill has proved useful in the tool collecting hobby though since I run across so many bent tools. This rare bent Plomb 1/4” drive pin handle needed a bit of straightening.
