I want to try it.

For he uninformed, it's explained in this thread on mod squad:

basically, the wheel is dressed with a diamond cutter spinner that can have any shape, not just the arc of a circle. So they cut it so the bottom of the blade is flat in the middle with narrow edges on both sides that gives you the grip of a 3/8" sharpening, but the glide of a 2" radius.
