Well, when I spotted it, I was instantly reminded of several different makes of lapping stone. So that is my intended use for it. The fact that it is a Norton Abrasives helped .

It is porous to an extent, but not nearly as much a pumice. Heck, I think it may even be more dense than a typical dual sided utility sharpening stone.
