I had (and still have, as it resurfaced in the Lego bin years later) one that used to be sold under the Quarrow brand. One of the first I EDC'd. It's still down in the basement. Really ought to get one of the WM versions. I'm a little short on dough this month, and maybe it's a good excuse to buy a couple sub $20 tools.
Quarrow also makes a big version of this little guy, which adds a few tools.
