There are, in fact, a large, and a small major radii Shibata cut stylus. The large cut has a 75um major radius, the same as the Microline. The minor dimension of the large Shibata is 6um vs just over 2um for a Microline. How could this possibly translate to a 2:1 better wear characteristic for the Microline vs the Shibata cut?
I would appreciate seeing the math that supports that conclusion. Wear is also changed by such things as stylus tracking force, quality of polish, cleanliness of records, etc, and I assume part of the assumption is that these factors are held constant. How do we get to this 2:1 wear figure with a smaller contact patch?
