I recently got one, but it's nowhere near the condition yours is in. Perfectly usable, but really beat up. It's a strong, and very heavy tool, but strangely, easier to carry and use than my big Leathermans (Super Tool 300 and Surge) as well as a newer SOG too, the PowerLock EOD.
Here's the smaller (just under 4") Micro Toolclip. One of the sturdiest small tools they make. But, I have retired it in favor of the big one, main reason, the clip. The slick Zytel pocket clip also has no bite, meaning it will easily get disengaged. I've lost one because of that.
In addition to the pliers, my favorite tool has to be its serrated blade. It'll go through some insanely thick rope.
SOG recently brought this model back, but instead of trying to make it good, chose it to be a $20 China-made model. It's got a few improvements, but also fails. The pliers have a lock in the frame (as opposed to the Zytel bail of the original, which often broke off--it was already gone on the two I've had) and a strong steel pocket clip. But the pliers were spring action (often meaning, the lock would get disengaged, and it would fire open in your pocket), the steel and buid quality cheap, and no serrated blade. I bought one and it lasted about a month. I bought my first Seki model to replace it, and then lost it about a year later. It was replaced, and while it does see use, I've largely retired it in favor of the full-size model; despite it being heavier and bigger. I may try modding the Chinese one's steel pocket clip into the Seki-made tool.
