While the discrepancy in their overall ratings is negligible, the Amesser A-65 and the Mueller 4-stage sharpeners don’t share similar scores in every category.

In speed, for example, the latter has the upper hand. It took much less time to sharpen a knife to a serviceable level. Not only that, but the Mueller could bring the knife to a higher level of keenness compared to the Amesser, when given the same amount of sharpening time.

The Amesser, on the other hand, didn’t shave as much steel off the knife’s edge as its Mueller counterpart did. We also ended up with a more refined edge compared to that produced by the Mueller.
