I've had a couple of Sebbies and a Strider AR and a Strider frame lock which I forget the name for it, SNG CC or something and one other from them that was a liner lock an RC. Haven't owned a PXL or X 18 but have owned Barr's, MercWorx, Adams, Clark's, Ellishewitz, and a whole bunch more that slip my mind. Oh a couple of Lightfoot's which are on a par easily with this Duncan. The others maybe not so much. Some would show tool marks of some sort or other, blades not centering, not sharp etc. etc. Save for the sebbie's as they were pretty much perfect out of the box for build quality. Just didn't care for grip ergo's on them. Oh yea a hand ground Emerson but not a custom and ltd .ed. fixed blade from EKI. High end BM's, Spyderco's, kershaws, Bokers, CS, etc etc etc. The Duncan blows them all out of the water for quality of build and attention to detail. Lightfoot knives are the same way I have found. Anyways like I said don't care for what the builder has done to folks but I don't think this particular knife buy supported him in anyway shape or form outside of me owning a high end folder. keepem sharp
