Posted By: Ryan RI've messed with this stone for a few months and I have to say I like it quite a bit. It is kind of a medium hardness stone, it will release abrasive somewhat easily and is possible to gouge but it's not super soft to the point it's annoying. I find it to be a somewhat good compromise in the hardness department and I think it needs to be like this in order to work like it does with very wear resistant and hard steels. It has a very nice feel and feedback and at 30mm thick it should last a while. It needs a decent soak and doesn't dry very quickly. The real strong point of this stone is its ability to cut high wear resistant steels just as the description states. I recently touched up a Manix 2 in CPM-M4 on this stone and it had absolutely no problem cutting that steel, anyone who has sharpened M4 will know that's not a small feat. I took the same knife to a Shapton Pro 5k afterwards and could immediately tell that it wasn't cutting this steel nearly as well, had a very strange feel and feedback of the knife basically skating across the stone. So if it can easily cut CPM-M4 it shouldn't have much problem with any of the other "super steels" out there. As far as the edge produced by the stone it obviously differs from steel to steel and knife to knife. For the most part it will produce an aggressive edge for 2k on your typical steels because it cuts so aggressively into them. Once you get into harder steels it produces less tooth and more polish as you would expect. Overall good stone that I will mostly use after diamond plates for really stubborn steels.
