My emergency melodeon repair kit, kindly made by the Swiss Army Knife/Victorinox Co. Size of a credit card, it has a very sharp knife for the bellows, a screw driver for the buttons, tweezers to pull the reeds out and if all else fails, a toothpick to poke in the eye of the player.

Seriously, my desk drawers contain a sewing kit, a screwdriver kit (Christmas cracker prize from expensive crackers... changeable screwdriver with 2 flat, 1 cross heads and a spike, and a tiny adjustable spanner/wrench), nail clippers, nail file, clear nail polish and various painkillers and cough/cold remedies.

And a tin of soup.
