The Leatherman Pulse tool is an attractive member of the "second generation" of Leatherman tools. Like the larger Super Tool 200, it has curved thumb grips to release the blade lock. The Pulse was introduced in 2002, and soon replaced the PST II. It only lasted until 2005, when it was replaced by the much more drab Kick/Fuse/Blast family. The Pulse is a popular collectible model, and also an extremely useful tool.
