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...
