By the way, I recall someone mentioning some belts only available by the case. How many in a case? Depending on the end cost and number of belts, I might be interested in going in for part of a case.

More than a life time supply for several sharpeners -
In addition to the 120 grit belts I ordered this afternoon, I just found these 150 grit and ordered 3 for about $8.50. Price for a case of 200 belts is $684.51. Hopefully they will be able to combine my two orders so I don't have to pay 2X UPS shipping which will probably be more than the cost of the belts.
I didn't know they carried 150 grit Cubitron belts. But, these 150 grit belts are listed as Cubitron, not Cubitron II. I don't know what the difference is and I have been unable to find out by searching online.

Mr. Grepper, in my understanding the difference between Cubitron and Cubitron II belts is in the size, shape and orientation of the grains. Cubitron ceramic grains are randomly oriented while Cubitron II grains have the same triangular shape and are oriented. I assume that the grains are made of micro-crystalline aluminium oxides.
Those Cubitron II grains are definitely nicely shaped little triangles, but in that picture at least they sure don't look very oriented. I was hoping to see them all standing on edge like little soldiers.
I was searching around and found this somewhat uninformative sentence from 3M. From my point of view it doesn't really describe the difference very well:
"The precision-shaped grain found in 3M™ Cubitron™ II Abrasives combines the advanced material properties of our original Cubitron grain with the precise microreplicated structures pioneered in 3M™ Trizact™ Abrasives. As the triangular shaped grain wears, it continuously fractures to form sharp points and edges."
