Best Electric Knife Sharpeners - FAQs

Are electric knife sharpeners safe to use at home?

Generally, electric knife sharpeners are safe. However, it is still essential to read the instructions thoroughly before trying them out to know what to expect. You may also start slowly until you get a feel of the sharpening process. This will allow you to adjust your grip to a more comfortable position and angle your knives better for optimal results.

Do electric knife sharpeners require regular maintenance?

The most common electric knife sharpeners require little to no maintenance. At most, you will need to clean them manually by wiping off the exterior surface and the disks with a soft cloth once you see dust build-up. Cleaning will depend on how frequently you use the machine.

How often do I need to sharpen my knives?

It depends on how often and for what purpose you use your knives. As such, when your knives become challenging to control and cannot seamlessly cut through, then you will need to thoroughly re-sharpen them. However, you can often go straight to the polishing stage and quickly pass your knives through it if you want to get that fine cutting edge.

How will I know if the polishing disks need to be cleaned?

Once you notice a decrease in the stropping disks’ effectiveness, you will either need to clean them or replace them. This ultimately depends on the electric knife sharpener brand you chose.
