Noun

 * 1966, Joseph McElroy, A Smuggler's Bible, p. 137:
 * It is a "seven-level" screwdriver, so-called by electronic technicians, who use this plastic-handled tool with the two-and-a-half-inch blade for so many purposes – chipping, hammering, a low-voltage shortening bar, prying – that they rely on it constantly.
 * 1966, ibid, p. 228:
 * [H]e takes from the breast pocket of his khaki shirt the little seven-level screwdriver he took from Michael Amerchrome: Plastic handle insulates, so seven-level may be used as low-voltage shorting bar, though the metal pen- (pocket-) clip on the handle's side makes you wonder; large enough for a firm grip; light enough to be used as a mallet on delicate components; small diameter of shank permits its use as a probe in confined places or as a chisel to scrape away corrosion between narrow-printed circuit channels; when magnetized, the small shank can retrieve metal parts that fall into restricted spots ....
 * 1989, Tony Tanner, Scenes of Nature, Signs of Men, p. 207:
 * For now I will temporarily purloin that seven-level screwdriver (as David, a character in the book, steals it from someone else) to pry open McElroy's seven-leveled book (as David uses it to open the actual smuggler's bible in the book which contains his manuscripts).
