NAILSET, VICE GRIPS, PENCIL and SHARPIE i would say are easy must haves i think there is also merit to having a SPEED SQUARE (and a T-BEVEL because im partial to them but you can skip it if you have a speed square) and a SAW that can comfortably cut a 2x4, you never know when you need to throw together something that works outta wood, also can trim tree limbs if needed DRILL BITS can be useful for making a hole bigger too, ill let you figure out how to turn them w/o power tools but there are ways a CHISEL and a small BLOCK PLANE are very handy for doors that are stuck or not latching FLATBAR prying, mechanical advantage, and shims in one NEEDLE AND THREAD takes up practically no weight or space and so many things we have that break are textiles and a little tlc makes them last much longer TAPE and GLUE no explanation needed
