The Leatherman Legend When Tim Leatherman founded Leatherman Tool Group Inc. in 1983, he set out to create products that improve people's lives. The Leatherman brand began in 1976 when Tim took his wife on a car trip throughout Europe. Plagued by fix-it situations, Tim created a cardboard prototype that would later become the ultimate pocket survival tool. Seven years and a great deal of hard work later, that prototype finally became the first Leatherman multi-tool. 21 double-ended bits gives you 42 additional tools Compatible with many Leatherman tools with a fixed bit driver (Charge models, WAVE+, Skeletool, Surge and MUT models) Also compatible with removable Bit Driver (not included)Included bits: Square Drive #1 & #2 Torx #6 & #8 Torx #10 & #15 Torx #20 & #25 Torx #27 & #30 Eyeglass Screwdriver Pozi #2 & #1 Hex 1.5mm & 2mm Hex 2.5mm & 3mm Hex 4mm & 5mm Hex 6mm & 1/4 inch Hex 7/32 inch & 3/16 inch Hex 5/32 & 9/64 inch Hex 1/8 inch & 7/64 inch Hex 3/32 inch & 5/64 inch Hex 1/16 inch & .050 inch Phillips #1 & #2 Phillips #0 & #3 Screwdriver 3/32 inch & 1/8 inch Screwdriver 5/32 inch & 3/16 inch Screwdriver 7/32 inch & 1/4 inchCompatible with: c33B c33Bx c55B c55Bx c55Bx Charge AL Charge ALX Charge Ti Charge+ TTi Charge XTi e306x e307x e33B e33Bx e55B e55Bx h502 h503 MUT EOD Removable Bit Driver Skeletool Skeletool CX Skeletool SX Original Surge Surge Wave+ MUT Cam Rail Piranha 2 Pump Signal®
