I am impressed with my Spyderco CPM S30V and CPM S35VN blades and assume the CPM S110V is harder and a step up. I've read that sharpening difficulty with CPM S110V is equivalent to ZDP-189. What I've learned to touch up ZDP often and not let it dull. If you do have to re-profile the blade use a light touch and be patient. It should be a cool knife.
It's being called "blurple" by a lot of people because although it's supposed to be blue it almost looks purple. Distinctive I guess but not my first choice in colors. Lucky for me I mainly care about function since it will be in my pocket most of the time.
I hear that sharpening is a bear so I'm thinking about sending it into Spyderco to have them sharpen it for free. They hold an edge so long a person wouldn't have to send it in very often. It would probably be cheaper than buying some of the systems people suggest for sharpening that steel. I have a Kershaw Blur that's actually been a really good knife for the last 6 years. I intend to send it in for servicing once I get the PM2. I could alternate back and forth and have the companies do the work of sharpening which both do for free. I moved almost 3 months ago and I haven't needed to sharpen the Kershaw in all that time. And I've used it a lot in that time. One thing I did was to cut down the hickory cane I have to add a different head. And that's aged heart of hickory. It didn't seem to affect the Blur at all. And it's S30V so the PM2, which has S110V, should last even longer.
