There are two reasons why a variable speed belt grinder is required. One is over-heat, the other is over-grinding. But....
1. Over-heat
: The heat can be controlled by the pressure as well as the speed. And we can often cool the blade with water(Of course, ice water is better). In addition, Bark River and Ken Schwartz said OK.(https://youtu.be/4cfCYb-Gamg) As you know, Bark River is one of the world leading outdoor knife maker and Ken is one of the masters of knife sharpening.
2. Over-grinding
: In same belt, the amount of grinding can be controlled by the pressure as well as the speed. And besides, we can use finer belts.
So I'm not sure the variable speed belt grinder is necessary for sharpening.
How do you think about it?
