Which multitool has the longest knife blade?

The Leatherman Super Tool 300 and the Leatherman Super Tool 300M tie as the multitool with the longest knife blade in MultiToolDB, at 81.3 mm (3.20 in). Next come the Leatherman Surge (78.7 mm) and the NexTool Black Knight (77 mm).

53 of 167 current models that qualify have a verified blade length and are ranked. The other 114 are left out rather than estimated. 12 discontinued models are excluded. Current models with a knife, ranked by the blade length the manufacturer publishes; a multitool here means at least five manufacturer-counted functions and a knife, pliers, scissors, screwdriver or pry bar. Limited and dated editions are left out. Many makers publish no blade length, so this ranking covers fewer models than the weight rankings.
