One use tool collections annoy me. I have a pile of tools I used only once because I needed them for projects, and it was cheaper to do the job myself vs hire someone with the tools. I imagine there is a lot of that for the home DIY crowd around here. One tool I can think of is a nursert set that includes the tool and a bunch of nutserts I bought on Amazon for $50 or so. I needed to attach a steel door strike plate securely to a thin piece of sheet metal behind that was stripped out and sheet metal screws wouldn’t work. I have had it for years now and it takes up a good bit of space. I also bought a cable toner just recently to try and chase down some wiring in a warehouse and likely won’t ever use that again. But it cost me $60 and I know an electrician would have charged more. I want to get rid of some of the stuff, but I’m sure if I do then I’ll come across a need. I need a second tool chest just to store all this stuff.
