I bought this knife a few years ago and have carried it off and on. I wanted to test the steel and see what it could do. After much abuse and use, I decided to clean it up and re-polish it. After a lot of elbow grease in the hand sanding department, I became a believer in the steel. It is extremely hard. It gets incredibly sharp and holds an edge like no knife I have ever used. And continues to cut when other high performance knives go dull. I think they discontinued the blue color, by I highly recommend this knife anyone looking for a high performance steel knife. My personal favorite knife steel prior to owning this knife was D2. I have a Chris Reeve Classic Sebenza in S30V. I have a custom neck knife in S90V. But for the price and performance, I just loved a D2 knife. My favorite D2 knives are those made by Bob Dozier in Arkansas. I now have a new favorite knife and knife steel that will be carried everyday.
