I have a Greco Companion that’s like your Ranger was. Completely uneven primary grinds, plunge line botched and uneven on both sides, swedge uneven on both sides, the list goes on and on.
The handle is paper micarta and was too slick so I filed some lines in both sides with a needle file. It wasn’t as thick as I wanted either, so I made some orange liners for it out of a Gojo soap jug. I sanded the spine all the way around, sanded the grinds, and left the flats black powder coat. This accentuates the uneven grinds even more.
All that said, it’s truly lived up to its name. It’s been a damned fine Companion. It’s been beat to hell and back, is chock full of patina and character, and holds a nasty edge. It just grins at me like a four toothed cage fighter begging for more.
IIRC, I bought it from Bob Quinlan 1999-2000 ish. He had just gotten home from Blade show that year and had spent too much. Took it off his hands for the princely sum of $50. It’s one of my favorite knives I’ve ever owned and I’d never part with it.
