Interesting point, I heard opinion the flat ground blades are harder on the bearings.

 

 

Not sure how you could quantify that theory really. So many variables.

I think of the hollow ground as a knife and the flat ground as an axe, the hollow ground are better on stringy stuff.

I converted an old mower grinder, the grinding head can rotate on the upstand to do both hollow or flat ground.

Its only an old clunker of a thing but it does a good job.
