Tangental, but one of the most useful tools I have my garage is a rubber mallet of all things. I would have never thought a rubber mallet would have so many random, odd-job, uses (e.g. when you need to apply pressure but without breaking force). Makes me wonder what are some software equivalents of "rubber mallet", tools you wouldn't think of but end up using quite frequently and, when you do, its perfect for the job in an incredibly specific way.
