Busse Custom Shop knife. Purchased this recently, David Brown made the sheath. Just been sitting unused since I got it as it is still too big for an edc I was looking for (resigned to a folder now for edc :-(...). Anyway, unused condition, INFI, sheath is dark grey with tech lock plus drop loop. Please ask if any questions. $ 400.00 shipped in CONUS usps. I accept applepay or usps money order.
