I always carry some small tools to make adjustments and minor stuff. I will take a pic of the box later but it includes:
- fret dressing file
- fret crowning file
- nut slot files
- a couple of needle files
- two Ibex violin planes, smallest size flat and curved
- miniature model saw
- single edge razor blade
- small knife
- screwdrivers for tuners
- superglue
- baking soda
- glass beads from the craft shop
- eraser shields
- tiny wooden wedges
- pincer
- small squares of fine grit sandpaper, from 600 to 2000
- 2 inch machinist square
- miniature drill (pin vise) with small diameter drill bits
- half pencil
- enough bone bits to make a nut or two
I think that's it. But there might be a few more tools there. Most of these live in the box all the time, and I whip it out when I do the last steps on a uke, fret work, nut etc. So the box is used and tools come and go as my methods or preferences change.
