IMO 1K or the bevel set, is the sharpening level, as Glen mentioned. After the bevel is set the edge is not going to get any sharper, just smoother and easier to work with. For instance, if you can pop the hairs at 1K, your still able to do this at 4K and 8K but it just becomes easier, or smoother, if you will. I have read that where the real "sharpness" is at, is in the bevel angle. The lower the angle, the sharper the blade.

+1 here....
