Sharp Field Sharpener and this case does it much better! One of the concerns I had when taking the Work Sharp into the field was that it wasn't possible to carry it with me without the possibility of losing sharpening parts or breaking the ceramic shaft. Well, this case solves that problem. Work Sharp sits perfectly, doesn't rattle. The bag is small enough to easily fit in a backpack or briefcase. The case was solid and still looks great! Bought another case for my son's Work Sharp!
