Do Knife Sharpeners Wear Out?


Since it is natural for knife sharpeners to eventually attain rugged surfaces, you might wonder if they really have the tendency to be useless in the long run. Let’s find out – do knife sharpeners wear out?

Stone bars get smaller with long-term use.

Knife sharpeners made of stone have their limits. In fact, the best type with 1,000 grit can only sharpen about 350 knives.

Additionally, coarser stones wear out even faster. Their particles are much bigger, making it obvious whenever the stone loses a bunch. The result is a smaller size.

For a longer lifespan, resort to fine stone bars. They can last longer even if they would sharpen a lot of high-quality kitchen knives.

Sharpening steels become smoother when worn-out.

Some people are using knife sharpeners made of steel. This type of sharpener is more convenient since you can move around while using it. It looks like a small sword.

Just like any other tool, a sharpening steel obviously wears out in the long run.

Steel can last up to four years with heavy use. You’ll know when to replace it just by running your thumbnail on the surface. If you can still feel the rough grooves, go ahead and continue using the sharpening steel.

On the other hand, if the surface is pretty smooth already, hit the store and buy a new one.

The machines of electric sharpeners wear out.

An electric knife sharpener clearly won’t work if it doesn’t have a machine. In the end, however, the machine naturally gives up.

All machines gradually experience surface degradation. Factors include chemical change or corrosion as well as mechanical damage.

Changing temperatures and moisture can contribute to corrosion. Meanwhile, heavy use is the common reason for mechanical failure.

In Conclusion

Do knife sharpeners wear out?

The three major types of knife sharpeners – stone, steel, and electric – eventually wear out. There’s no exception. This is a normal thing for tools, so don’t worry if you have to make another purchase.
