Aviation snips: see Hacksaw

Douglas Fir 2x4: used to lever a vehicle upward to aid in removal of a Floor Jack from beneath it.
Tweezers: used for removing splinters, see 'Douglas Fir 2x4', above.
Timing Light: a stroboscopic device designed to illuminate grease buildup.
1/2 x 16 Inch Screwdriver: a large motor mount prying tool that inexplicably has an accurately machined screwdriver tip on the end without the handle.
Trouble Light: the mechanic's own tanning booth. Sometimes called a drop light, it is a good source of vitamin D, "the sunshine vitamin", which is not otherwise found in garages at night. Health benefits aside, its main purpose is to consume 40-watt light bulbs at about the same rate that 105-mm howitzer shells might be used during, say, the first few hours of the Battle of the Bulge. More often dark than light, its name is somewhat misleading.
Gasket Scraper: theoretically useful as a sandwich tool for spreading mayonnaise; used mainly for getting dog ---- off your boot.
