Jon, though I have my own set of tools here it ended up doubling up (at least) on some tools when I inherited all of the tools from my father's house. There were some interesting ones that I didn't figure out what they were for until I actually needed something and had an "aha!" moment and went to retrieve the device.

It is the same as your house with boxes of screws and nails and other fasteners. I usually buy the size package closest to what I need but sometimes you end up with a pound box of nails or screws - there are lots of those stacked on the shelving in the garage. I keep scrap pieces of lumber and am regularly able to put them to use as I modify or finish something I've been working on, so the bin under the workbench is full and in the corners of the garage there are pieces leaning against the wall. The point of pride in my garage is that there is plenty of room to park the SUV and get in and out on either side without squeezing out or banging the doors into something. I refuse to let my garage be one of those that the car is always parked outside of and when the door is up it can be seen to be crammed completely full.
