I'm almost positive it's not micarta. I have one, and I pulled the whole thing apart to tighten it up. The overlays look like cheap, thin plastic with a screened on pattern meant to resemble micarta. I'm not sure what the frame is made of, but if the blade is 440-anything, it might be worth the eight bucks I paid. After tightening the screws on the liner lock inlay (one of which twisted apart at the screwhead), mine locks up tight, but all the way to the right. The detente is not a ball, just a semicircular area mashed out of the lock leaf, and since the mating hole in the blade was drilled a bit oversize it doesn't hold the blade all the way in very tightly. The tip of the blade can creep out of the handle before it meets any resistence. All in all, though, it wouldn't be a bad knife to use for, say, cutting buried landscaping plastic or something or for trying the pattern before ordering a handmade from Tom.
