I have one myself, and I love it. I lowered the angle and it still has a very stable edge. I would like to do some comparison between this and my k2 in10v.
I am curious as to what the hrc range is as well. There is an old thread here where the mules were tracked and updated with hrc values and ranges. It appears that the thread lost steam. I wish we could know the target hrc for a few others as well such as the 20cv and pd#1.
I just wanted to say I really appreciate you giving us hardness info on blades. I realize you are not obligated to do so as well as reasons for keeping the info private, but I for one absolutely value the info and it makes me more likely to buy.
