I was torn, I voted no but there are a select few I would lend to if they lived near me. Oddly enough, this is the same group of people I would give a kidney to.
I would say anyone who works with their tools, actually depending on them for a living doesn't lend them out or is at least is a lot less likely to.
My tools are very personal to me, whether it's a cheap screwdriver or a complex machine, I acquired them for a reason. Whether it's making or repairing something, tools are part of what make me who I am. I'm not lending them out to anyone.
For me, the rule is, you don't ask to borrow and I won't have to say no.
