I know we have several professionals and shop owners here that will have every tool and gadget known to man. This question is MAINLY from a "personal" perspective. What tools do you have to keep your gear in top working order, and Which pieces do you consider "must have" items e.g. nock squares, string jigs, serving tools, nock pliers. D loop pliars, bow press, hooter shooters....and all of the other stuff you have.
