I had forgotten this from the AD&D 2E Arms & Equipment Guide:
A thieves’ toolkit comes in a flat, folding leather case or a rolled suede case and includes dozens of small tools. A set normally contains 20 wires, ranging in gauge from the thickness of string to that of a slender pencil. Each is approximately 12 to 18 inches long.
These are used to poke into small holes or push trigger or buttons from a short distance. The toolkit also includes a set of 12 skeleton keys that fit many standard locks. Also in the set are several screwdrivers, a wire clipper, clamps, and pincers ranging in three sizes from minute, small, and average. Bundled with this package may be a small chisel, hacksaw, and hammer.
In some of the more deluxe toolkits, small vials of metal-eating acids may be found, along with magnifying glasses and slender pieces of high-tempered steel that are used as miniature crowbars. A thieves’ toolkit will range in weight and size greatly, depending on the initial cost of the package.
Basic 30 gp
Deluxe 50 gp
Ooohh, acids that eat metal!!! Oh yeah, I'll take a few vials of those!!
