Does Swifty Sharp Work? Our Review

Knife sharpeners have been a mainstay among late night television infomercials for decades. With Swifty Sharp, we have a motorized knife sharpener that is said to work with any knife and includes a guide which holds blades at the “perfect angle.”

Resembling an electric pencil sharpener, Swifty Sharp sports a plastic compact design that includes a catch tray to collect metal shavings.

Although it is touted as being cordless, this may not be a desirable feature, as it means you must keep it stocked with four AA batteries. As batteries lose power, the motor works less effectively. We would gladly sacrifice portability for a DC powered motor.

How well does Swifty Sharp work? As stated, the motor does not seem as powerful as one might expect, perhaps due to being battery operated. A fresh set of batteries is a must. An extended sharpening session in our tests led to the unit getting quite hot, which is gave us a somewhat uncomfortable impression.

Swifty Sharp seemed to work best when knives were gently placed in the unit, as any pressure seemed to work against the motor. Our conclusion is somewhat mixed, as we did achieve successful sharpening of some knives, but not before the unit heated up and weakened with extended use.

Online reviews for Swifty Sharp run the gamut, with a no clear consensus. We’ve seen ratings range from 1 to 3.5 stars. It may be worth a try once it becomes available in stores.

Bottom Line

Swifty Sharp is an As Seen on TV blade sharpener. Being battery operated tends to be the biggest obstacle in the product’s success. We were able to get it to work moderately well, but it requires little pressure and doesn’t seem to be geared toward extended use.

    The motor on mine, stopped as soon as the knife blade touched the stone. You didn’t have to put pressure on it, just let it touch.
