I may be missing something(probably my mind!) but all the bench grinders I have seen rotate in a CCW rotation. But I see all kinds of "wheels" advertised for sharpening and honing wood chisels and carving knives.
It seems to me that if you tried to sharpen a knife or chisel with that wheel rotating toward you the tool would just "dig in" and maybe sling it away from you or into your stomach or an eye. I understand that this wouldn't matter if you used a stone made for grinding and fabricating metal parts, although I know from experience they will catch sometimes also.
Is this a problem when sharpening carving tools or is it just something you have to master like turning a hunk of wood on a lath? I don't think I could ever "master" honing a carving knife on one of those layered leather wheels with that sucker rotating toward me!
