I like the vibe, but I would be really worried about someone breaking into it.
There are a couple of places online that will sell you a more complete repair kit, but what about if you just want stuff to repair stuff on the fly? Like an emergency kit?
Mr. Pimentel put together a good toolkit for fixing stuff on the go. As in NOT replacing pads or springs.
I think it’s really valuable to be able to do a few small repairs on woodwind instruments. As a doubler, I’ve found it to be a financial necessity—I can’t afford to run to the repair shop every time some little thing needs tweaking on one of my instruments—and it’s a great way to get to know your instruments better. (I do still make sure my instruments visit a real professional on a regular basis.)
Good tool list generally, though I’d put some strips of cardboard (to make wedges and what not) in there for propping open keys or mechs to allow easier fixing.
