My first Leatherman was also a PST, dated 0400, according to the date stamp on the inside. I noticed it in the hands of one of the husbands at a weekender 22+ years ago in which we were knocking about in the woods while the wives were up to something at which we were excluded (nothing naughty!). I was, to say the least, intrigued, and asked to examine it up close. It was the first multitool I ever laid eyes on, and was much captivated by the thought of a full sized tool multitool with all the trimmings that could fit in a pocket. ASAP, when I got home it was just about the first thing I acquired, and was quite happy with it for a time. Eventually, however, Leatherman came out with something similar, but loaded with even more implements, so I bought that and passed the PST to my son, an artisan who abused it something awful. That gave me the opportunity to send it to Leatherman for a refresh, and it came back two weeks later in like new condition. By that time, my son had settled on something else, so I got to keep it. So, I like the company, the service and the tool, which has resided in my tool drawer ever since, a keepsake of my first multi-tool, and the only one of a dozen or so the has any sentimental value.
