Resurfacing a coticule stone?

Hi guys, Santa made an early appearence and left me with a Belgisher Brocken yellow coticule stone. It's originally meant for carving knives etc. but of course I have a different idea. This is one of those stones that has been laminated with some other kind of grey stone as a base. There are a few flaws in the yellow portion but the problem I have is that the surface grinding seems to be a bit rough... Has anyone flattened a coticule stone before? And if so, what did you use? The stone is about 2" wide and 4.75" long and in a parallelogram shape. I think it's large enough for polishing if I can get the entire surface smooth and level. I've checked it out with some of my smaller carving knives and it does do a very nice job on those...

Well, I think you can't go wrong using a pumice stone. But, since I don't have the coticule, maybe someone else here (Lynn) can tell better...

6AM here, sorry...

Christian it sounds like you have a coticule mounted on a bed of slate for strength. The coticule by itself isn't especially durable. That sounds fine. I have a couple of belgians, and I lap them in the same manner as other stones. I use a DMT 11x4" F/UF diamond hone. If you don't have a DMT, you can also use sandpaper. By that I mean, take a sheet of wet/dry sandpaper, say 600 grit, wet it, lie it down on a smooth, flat surface such as a sheet of glass or a marble countertop, and rub away with your stone. The wet paper should stick well enough. You can periodically check the surface of the stone and see the high spots beginning to fade away. When the entire surface of the stone is making contact with the sandpaper, I'd replace the 600 grit with a sheet of wet 1200 grit and give it a few more strokes. Rinse well and then you're good to go. .............Jeff

I have not had to resurface mine, but I have been told that a few strokes with a 600 grit wet sand paper does a nice job. Lynn
