Woah Ed - that is a cool rock! The box has hinges, I'd be interested to inspect how they were fabricated, of what, and how they are fastened to the box. That thing belongs in a museum!
The Bosch jigsaw blade is a recent tool-of-necessity. When replacing an acoustic steel-string bridge, I needed to move the peg holes so I filed the old ones with dowels tapered to fit snug and glue tight. Well, when it came time to glue the new bridge on, I realized the dowels were sticking out of the bridge plate and keeping the inside caul from sitting flat! The caul already has access holes for alignment pins, so I didn’t want to Swiss-cheese it for the dowels. I looked around the shop and considered my little butt-chisel (also pictured) – No way in there. Also considered just grinding them down with 60-grit paper on a little sanding block – but that hurts my wrist just thinking about it even now. Then I found I already had this aggressive little blade that can cut flush against a surface and fit between the dowels. All it needed was something to hold on to. So I CA’ed a chunk of dowel on the tang, and bingo, I was done with the job in 5 minutes.
Might as well finish with the rest of them (I’m at work now, not in the shop so I have time to kill

- The ½” butt chisel was made custom for me by Dave at Blue Spruce. It is O1 steel so it holds a super-fine razor edge that can shave fibers off end-grain spruce or sharpen a pencil – it’s my constant companion.
- The gold-handled chisel is an 1/8” lathe tool ground to a chisel point and held by a slightly altered pin-vise. Indispensable for a bizillion tasks like cleaning the glue out of a nut channel.
- The big chunk of tool steel is a 3/8” lathe tool that is basically in its stock shape but with all faces ground to a fine grit so all the edges are very sharp. That thing can scrape any surface free of glue or whatever and leave not trace at all. Great for lowering pesky frets.
- The scissors are not particularly keen, and they’ve been sharpened way too many times, but I inherited them from my dear old Dad who used them to cut fiberglass for a boat he built when I was just a toddler. Utilitarian and sentimental.
