Reviews for Lansky C-Sharp ceramic sharpener for on the road

I bought c-sharp after more than 2 years of using lansky blade medic. It is better for sharpening a variety of blades. On blade-medic it happened to get some edge rolling from the ceramic rods. Not with c-sharp. 600 grit is a good balance between speed of sharpening and a working edge. I expect Lansky to make a pocket sharpener with ceramic 15-20-25-30 degrees on a side and carbide 15-20-25-30 degrees on the other side. That would make more sense.
