I have an Imp in Silver G10. Cool little knife. I rarely carry it though because I don't like the sheath. The sheath is too soft and tight, which makes it a pain to remove the knife for use. Without the sheath, the thumbstud is so long and the detent is so light that I'm afraid it would open in my pocket very easily. I normally carry an Al Mar Hawk to the office, which is perfect. The sheath is stiff and just tight enough to hold the knife, but loose enough so that the knfe slides out with gravity when I want to use it. If I can find a good replacement sheath at a knife show, I'll be carrying the imp more.
Another thing I don't like is that the anodizing on my imp is uneven. Near the top one side is blue while the other side is magenta. It's not major, but I hate showing my knife to people because it's the first thing they notice.
