Looks a lot better than their current Cop Tool by Boker (since around 2010.)
I can't find who made the original $100 D2 one (circa 2007 or so), but it looks like this may be one of those, modded up.
WT221BK. Designed by Roy Huntington, made in USA. Came with a cord-wrapped handle, so the micarta would be a custom job. As would the partially-serrated blade. Looks like they came fully serrated.
There also seems to have been a Cop Tool2 at some point, but I can't find a picture or article on it - just reference to its existence.
Looks a bit longer than 6" OAL (mostly, blade longer than 1.5 or 1.75"), which makes me think it may be a 2.
Wonder if Ryan or anyone at Wilson would be available to chat about that piece, and who made the pricey D2 ones before Boker came in.
Don't think it had anything to do with the Becker...
Good luck!
Should be a handy little device.
