Just picked up a new Ontario (D-2 steel) TAK knife. I put it on my Lansky diamond sharpener. I estimate the existing edge to be about a 25 degree angle. As I prefer a 20 degree edge, a new profile was needed. It took a few hours, but I finally got the new edge I wanted (I like 20 degree edges on all my knives). It went better then I expected, as I figured it would take longer. I heard that D-2 is a pretty hard steel, which it is, and took some work to achive an edge. It is now shaving sharp and I'm now a happy camper. Does anyone have this knife, and how well do you like it?
