The KF4, though now retired, was introduced by Leatherman in 2001 with the launching the Juice line. It’s been released in “solar” yellow as well as “storm” grey. You’ll also see my customized beater in a few picks.
As far as the tools go, the KF4 tool list reads like a fully equipped large multi-tool, with the notable exceptions of scissors and can/bottle openers. Everything on this tool solidly snaps open with back springs like a slip joint pocketknife.
The original Big Boy of Multitools the Leatherman Super Tool
The Super Tool was the third tool produced in the Leatherman Lineup and the first 4 and a half inch tool. The Super Tool was produced from 1994 through 2001 where it was replaced by the Leatherman Super Tool 200. Also of note is that some of the early models of the Super Tool as with the early PSTs lacked a hard wire notch. The Super Tool had a great run in it's 7 year run. This is a tough tool that was built for everyday heavy duty use and abuse.
The tools of it where also bigger and beefier than it's smaller counterpart (PST) and each tool locked. It included 18 listed tools. A clip-point knife, a serrated knife, needlenose pliers, regular pliers, wire cutters, hard-wire cutters, electric crimper, small, med, large screwdrivers, a phillips head screwdriver, wood/metal file,a saw, a wire stripper, a bottle opener, a can opener, 9 in / 22 cm ruler, and an awl.
Similar to it's more affordable cousins, the standard Skeletool and the yet to be released Freestyle, the Skeletool CX is the premium model in this particular line. It boasts the same features as the standard model, but with a few extra bonuses.
If ever there was the One Tool to Rule Them All, it’s Leatherman’s Pocket (or Personal) Survival Tool, affectionately known as the PST. This was the original Leatherman production model, and the source of inspiration for all current issue multitools, and the One Tool (see?) that was single handedly responsible for resurrecting a virtually extinct niche market and bringing it to the masses.
Another member of Leatherman’s Charge family, the Ti is now discontinued, along with it’s original titanium handled sibling, the XTi . While the XTi was replaced by the ALX model, the Ti was replaced by both the AL and TTi models.
