My wife recently purchased a tool box at an estate sale with a number of carving tools (she is a wood carver). Among the various chisels and knives were several slip stones and other sharpening stones. One stone which I promptly stowed away was what looks to be a NOS 1 X 2 X 8 item marked Norton KB-8 Queer Creek Sharpening Stone, Made in US of A. The surface is pristine and seems to be a quite fine grit. A Google search just gave some individual’s guess that this stone is in the 600 – 1000 grit range. Does anyone know with any degree of certainty what the grit is? Question #2 is there any down side to using what probably was intended to be an oil stone with water as the lubricant? I already use water (or honing solution) with my water stone and steel diamond plate.
