I’ve been curious about this since it was released, so I decided to give it a try. I bought a PMV-11 blade for my favourite plane, a Veritas small bevel up smoother.
The back of the blade has been lapped so I spend about 5 minutes polishing it on a 8000 grit diamond stone.
I honed the blade on my diamond plates. The blade was ground at 25 degrees so I honed a micro-bevel at about 26 or 27 degrees. It seemed to sharpen about as quickly as O1 steel and sharpened to a very keen edge, comparable to O1. I honed at the low angle to see how the edge would hold up.
I’ve been using it for about a week of light use on red oak, pine and cherry, both end grain and face grain and including some nasty knots in the pine. The edge has held up very well so far. Next time I sharpen it, I’ll go for a higher bevel angle to see how that stands up.
