Another thing I do is that I dedicate certain tools for certain tasks only. Like my tools for fretting, they never do anything else. There are other saws and files for other things. It's kind of costly but to me it's more practical in the long run, and for fretting, everything has to be in accurate shape.
Same with my hand planes, some are used for general shaving but some are dedicated to a few jobs only. That's why I have lots of them hehehehe.
