I've been to a couple of similar estate sales. Usually, one could write a story about the retired guy wanting to get out of the house or the old farmer liked to have an excuse to go into town and hang around the big store. He'd always buy something every trip. There were duplicates upon duplicates of most every hand tool.

My father in law was that way. After he retired, he fished almost daily for a while. As he got older, he didn't want to go to the trouble to get the boat out, so he looked for other things to do. He got to going downtown and going through the thrift stores and pawn shops. He brought home tons of stuff that was a good price. It got out of hand. His entire workshop and garage became a hoarders nest, boxes floor to ceiling. He didn't even have tunnels, he had to remove boxes to get to anything. It would take him half a day to move stuff, get to his tablesaw and take it out into the driveway so he could use it. When the roof got to leaking, he couldn't even see it happening, and a lot of stuff got ruined.
I went to his place one time, and counted on a shelf 13 belt sanders, lined up next to each other. He had a box with probably 150 fishing reels in it, most still had the $.50 or $1 stickers on them from the thrift store. He had boxes of screwdrivers, sockets, wrenches, machine tools, carpentry tools, in duplicate, triplicate, even dozens of an item. When he died, his son had a yard sale and sold everything for a few hundred dollars. What didn't sell in that one day got tossed or sent back to the thrift store. For a few hundred dollars of hoarded value, he'd have been a lot better off with working space in the shop, or being able to park his car inside.
Just one more personal illustration of why I'm going through my stuff, getting rid of unused and duplicate tools. I want to only have what I use, and devote my space to organizing what I need so I can find it and have enough space to work in. I don't want to store stuff just to have it.
