I've glassed a razor and taken it to shaving on a BBW. Not too long of a process. I just did a dilucot type method, and it worked well. I got best results finishing using oil. It was definitely daily shavable. The edge was not as sharp as a coti edge I once had. That could be my lack of experience with the stone, it could be the stone, it could be something else.
Yes, you can use a BBW as an only stone. I would encourage you to try a few different stones and see what you like, then you can settle on whatever you want.
