If you follow the majority so far, it looks like it's VG10. That is always the case when this gets asked (which is often).
That's ok, more ZDP for me. I have my sharpening rig down pat and have a laser beam edge 24/7 with ZDP. You don't need to be a sharpening guru, I'm sure not. Just have to UNDERSTAND what your doing to the edge. See my sig, I own a number of ZDP's, sharpening is not an issue, may take longer than VG10 but many premium steels would take longer than it. Stays sharp longer-sharpen less, maintain the edge with a sharpmaker and strop.
