I have a Gerber LST that I got something like 15-18 yrs ago. It is my main fruit peeling/cutting knife. Carried it for the bulk of that time, until about 2 years ago. Haven't sharpened it much, so it can be cleaned up to look nearly new. Pretty sticky and hard to open/shut now from gunked up fruit juice.
I recently found the Case pocket knife I had several years before the LUS. I can't see any model # on it. It is about 3 1/4" long closed. It has 3 carbon steel blades. The largest one is a clip point, and lies in the center of the knife. The other two blades are shorter than the clip, both about the same length, and open from the opposite end. One is a clip also, the other a classic pen-shaped blade. It appears to have SS liners, on the outside, none between the blades. It has really good snap left, but it is too rusty to really use. Think that is what it was slowly doing the years I didn't know where it was. Never did take good enough care of it. I really liked it when it was new. Put it aside tho, when I got the lockback LUS.
