Expert’s Answers For Readers’ Questions

How does a knife sharpener work?

A knife sharpener works on a simple principle. They have blades made of an abrasive material that wears away the metal on either side of the knife blade to reshape it and create a new edge.

How often can you use a knife sharpener?

It depends on the usage. If you rarely use knives, they may require sharpening only three to four times per year. Frequent sharpening will keep the knife from going dull. Some knives made of stainless steel or carbon steel may require sharpening every other day.

How long should it take to sharpen a knife?

The time taken to sharpen a knife depends on various factors like the kind of knife sharpener being used, your sharpening skills, the type of knife and its condition, and how sharp you want it to be.

Do you push or pull when sharpening a knife?

The push stroke is also known as the edge-leading stroke, and the pull stroke is known as the edge-trailing stroke. The former hits the steel harder and removes more material. You can push or pull or even combine both strokes when sharpening a knife.

Do knife sharpeners cause damage to knives?

Knife sharpeners, especially manual ones, can jag the edges of your knife if used too many times. This damage can be prevented by using good quality sharpeners.

What are the differences between a knife sharpener and honing steel?

A knife sharpener chips off bits of the blade to produce an altogether new edge. This should not be done too frequently; once or twice a year is okay. Honing steel, on the other hand, pushes the edge of the knife once it starts to roll back, i.e., it corrects the edge without shaving much of the blade.

Manual vs. electric sharpener – what is the difference?

The main difference is the mode of operation. A manual sharpener needs continuous efforts with both hands, while an electric sharpener only requires inserting the knife a few times in and out.

Can I sharpen scissors with a knife sharpener?

No, not always. Not all knife sharpeners can sharpen scissors and may lead to unwanted burrs and rough edges. Check the manufacturer’s information to understand if you can use it for scissors.

What materials is the sharpener made out of?

The body of the sharpener uses sturdy materials like aluminum alloy, magnesium alloy, and ABS, hard plastic.

How easy is it to clean and store a knife sharpener?

Most knife sharpeners are very easy to wash and wipe with a cloth. Many are not dishwasher-safe. Remember to read the instruction manual carefully.
