I agree with donations to a worthy group who will use the tools. I would add to the list a shelter for women and families recovering from domestic abuse -- everybody needs tools.
I'm also a big fan of sets of tools -- I have my main cabinets at work, a dedicated bag for the car, and a dedicated toolbox in the house. The last thing i want to have to do is go searching for a good screwdriver OR use the wrong tool for the job.
I'll differ a little bit though -- if it's a low-quality tool, don't put it in your travel kit. If you break a wrench or strip a bolt or cause some other grief at home, that's one thing, but if you're under the car on the side of the road and you need access to a tool, you'd better have the right one there!
I know this has changed with cell phones, AAA, and computer controlled cars, but I've more than once fixed my vehicle 'on the fly' and made a big deal into a little one.
Or, say, a friend asks you for help, you come riding in on your white horse to assemble that Ikea desk, and, bingo, first try you strip out your chinese screwdriver, and your 'good ones' are in the locked shop 10 miles away. Oops.
So grade that tool, and if it's not a good one, don't put it in the travel kit. Put it in the 'modify' box, the duplicate box, or the 'loan to the other guy box."
Just my thoughts on it.
Peace!
