The most effective electrical knife sharpener I used whereas testing was the $160 Chef’s Alternative Trizor XV, a cumbersome gadget with three separate tracks for bringing uninteresting knives to a super-sharp 15-degree edge (many American knives are sharpened to a 20-degree angle).

They nonetheless may reduce tomatoes and pineapples (our two testing fruits), however not cleanly; basically, we needed our knives to behave like chef’s knives which have seen years of use with out a lot maintenance.
I examined the knives earlier than sharpening them to make sure all of them carried out about as poorly as we needed them to, paired every with a sharpener and labeled accordingly. I then adopted the instructions for every sharpener. Some sharpeners urged passing the blade via “till sharp,” and I did so till the enhancements appeared negligible. Different sharpeners had been extra prescriptive, and I adopted the instructions exactly.
After sharpening, I examined every knife, taking a look at how a lot it squashed a ripe tomato and tore its pores and skin whereas slicing, in addition to how simply it sliced pores and skin from a ripe pineapple. I rated the reduce with every fruit out of 10, noting my particular observations. The first objectives right here had been to see how sharp the sting grew to become and the way easy it was throughout its size: a pointy blade should not squash a tomato, and a easy blade should not tear its pores and skin. A pineapple would check the identical results in the next stress context — reducing via a sturdy fruit in a non-straight sample.
