How long do knife sharpeners last – Myth and Reality

Last Updated on April 6, 2021

Once a man came to me and said, “Hey, I like your writings and I knocked you to know a short answer to a silly question. But you didn’t reply to it.”
“What was it?”
He smiled and asked, “how long do knife sharpeners last?”
“It depends but if you take care of your knife sharpener properly; it lasts almost 4 to 5 years.”

He surprised and said, “how can a knife sharpener be last for 4 to 5 years?
So, I promised him to write content on my website about it. So, today we are going to discuss how a knife sharpener lasts for 4 to 5 years without creating any problems.

Different types of knife sharpeners need different treatments to prolong their lifetime. But in some general steps and care should be taken properly for all sharpeners.

How you can care of your knife sharpener

1. Keep your knife sharpener free from rust and make it dry every time after finishing your work.

2. “You can passively care your knife sharpener by caring your knife.” – remember it.

3. If you use a manual knife sharpener, always be aware of the sharpening angle. For example, you should not sharpen Asian knives like Shun by using a manual sharpener. Use a professional one to sharp your knife edge.

4. Don’t do the regular sharpening. Yes!!
You heard it right. If you sharpen your knives on a daily basis, both of your knife and knife sharpeners won’t last long. This is why regular honing is very important. Honing your knife once a week will indirectly prolong the lifetime of your knife sharpener.

5. Keep in mind that all of the knife sharpeners on the market are not suitable for all types of knives. For example, you can’t use any knife sharpener to sharp the serrated knives. So, if you already have a knife and want to buy a new knife sharpener; then choose it according to your knives. Don’t go for cheap and popular on market.
