Oh yeah, I also buy tools with no clear use in mind. That often seems to work out better than buying something I "have to have" that doesn't work out as intended and ends up collecting dust. Router bits........I had to create a spreadsheet to keep track of them. Not long ago there was something I wanted to do and I started looking online for the proper bit. I finally decided on the one I needed and before I bought it I checked my spreadsheet. Sure enough, I already owned one.
