I have a WH Carbon Fiber w/ 2.5" drop point blade, a few years old in ATS-34. It's a nice looking knife, blue titanium liners, carbon scales, nothing out of place. I rotate it in for EDC, and the carbon fiber is durable. I don't put it in with the keys, and it doesn't get hard use (opening boxes, mail, etc.) but it holds up well. 3 years, no scratches.The liner locks up solid & 100%. They do a great job. The price on this knife has almost doubled since I bought mine.
