I agree with Glen. However, like Phoenix51 I also use my BBW for knives - leather cutting knives, that is. The reasons are twofold:
1. It is hard enough to withstand abuse from small pointy blades, half-round and large curved ones, and more to the point
2. It is covered with little yellow dots, coti dots, and is really fast and fairly fine.
As for shaving off it, the edge is so-so, good enough but no wow-factor. My other hones do the job much better with regards shaving rather than knife maintaining, where the edge (for my needs - cutting and grooving leather) has to be 'stout' rather than frail and refined.
