How about one of Mirock's squares or ruler - I bought both last year (from memory after reading a post on here) and they are both now in my list of "go to" tools - I never realised how useful a transparent square could be, and the ruler easily fits in a pocket. https://www.etsy.com/shop/MirockToolworks
or (not quite woodworking) my other go to tool this year (due to garden rework) is this roughneck post digger - great for anything that needs leverage or roots breaking (tenuous wood connection!) https://www.screwfix.com/p/roughneck-17 ... gger/62496
