Multi-Tool A100

Multi-Tool A100 The A100 broke new ground in the world of multitools when it was introduced in 1997. Available a full two years before the Leatherman Crunch, it was the first multitool to feature locking plier jaws. Also groundbreaking at the time was its one-hand-opening, liner locking knife blade. Ironically enough, the double folded sheet metal handle with one hand blade was seen again the very next year on the Leatherman Wave.
