Knife sharpener

Test results for 16 knife sharpeners priced from $4 to $199

Keeping your knives sharp not only makes your job as master chef in the kitchen easier and quicker, but much safer too. If your knife is blunt, there’s a danger it could slip from the food you’re cutting and slice through your fingers.

Refining the already-sharp edge of your knife on a honing steel is a handy interim measure but eventually, depending on how often you use your knives, honing will no longer be enough to keep the blade sharp as the edge degrades with use. One of the safest ways to test whether your knife is sharp enough is to cut through a soft tomato. If it’s sharp, it will slice through easily. If it requires pressure to cut, then it’s time to run your knife through a sharpener. Eventually your knives may need professional sharpening though, which can be done at most good cookware shops.

To determine which knife sharpeners currently on the market are the best at sharpening and the safest to operate, we put three electric and 13 manual models to the test and found some to be safer than others.

Please note: this information was current as of May 2009 but is still a useful guide to today's market.
