The Amesser A-65 sharpener isn’t the sharpest tool in the drawer, nor does it create one. However, it still offered a better performance than the Chef's Choice 4643 in our tests.

Both devices have a sturdy construction with a great fit and finish. The Amesser gained good ratings for its substantial weight and soft, velvety cover texture, while the Chef’s Choice 4643 sports our favorite simplistic but highly stable base design. 

When it came time to actually sharpen a knife, the former got the job done more quickly and effectively. We also achieved a straighter knife’s edge. The latter, despite its elaborate wheels, took twice the time in our speed test and couldn’t achieve the same performance level. 

In the end, the Amesser A-65 is the more capable and the better choice between the two sharpeners.
