I thought I'd go ahead and post a pic of the two knives I referenced in my first post.
The top is a Wilson Tactical model 25, semi-custom. You probably have a better chance of seeing Bigfoot than seeing another one. I've searched for pics several times but haven't seen any since WT was still in business many years ago. I carried and used that knife for several years. The knife last saw regular use on construction sites.
The other knife is a Master brand "Alpha Team" model MU1132 (heavily modified in this pic).
There were a few incidents that made me reconsider carrying the WT, one involved a serious motorcycle accident I had while wearing it, but to avoid an excessively long post I'll relate the last, and perhaps most decisive incident-
I was on a job site, using my knife to hack through some old drywall following electrical wires. And between hacking and then stopping to pull away chunks of drywall with both hands I would place the dust covered knife on top of a nearby stepladder. Someone came by and bumped the ladder causing my knife to fall about 5 feet onto the cement floor. It landed with a loud assortment of clanks which sent a shiver of dread throughout my body.
I feared what I would find when I picked it up. It's a somewhat heavy knife (almost 1/4" thick, full tang) so it landed pretty hard. Luckily it didn't land tip down, and only experienced some minor "bruising".
The way I felt when I heard that knife hit concrete, and how I felt as I retrieved it, fearing what damage I would see, and the relief I felt upon seeing it was all right, made it clear to me that I valued the knife as more than just a tool- something to be used until it was worn out.
I decided that evening to find a suitable replacement. I had seen a pic of the Master here on BF, it had appealed to me, so I went searching online. The specs were near perfect for me (5-1/4" long blade, 3/16ths" thick, full tang, guard, micarta handles). Heck, it even bears a vague resemblance to the Wilson.
I searched around for the cheapest price, found it on sale at Amazon for $8., and decided I had nothing to lose. The knife ended up really surprising me, both in it's strength, and ability to take and hold an edge. It was the knife I carried and used at work, and away from work for the rest of my working days.
There are three ways in which I value the Wilson- 1. It's a great knife. 2. I just think it's damn cool. and 3. I like how unique and rare it is. Like I mentioned earlier, you're probably never going to see another one.
I'm retired now. And I probably have no actual need for a fixed-blade anymore. But the fact that my fixed-blades might never be used again doesn't cause me to value them any less.
