Best for Japanese knives: Chef’s Choice 463 Pronto Santoku Sharpener

Two-stage system for sharpening and honing
100% diamond abrasives
CrissCross technology for ultra-sharp results

Pros

A true no-nonsense human-powered sharpener that gets the job done
The ergonomic design keeps your hand out of harm’s way and allows you to hold the sharpener firm
Ideal for Asian-style knives with serrated santoku edges
Works for left and right-handers

Cons

It can take some practice to find the ideal pressure that should be applied on this sharpener

Our second entry from Chef’s Choice is the 463 Pronto Santoku. This manual sharpener is super simple to use and delivers fast, sharp results. While this is a two-stage system, there’s nothing complicated about it. One slot is for coarse sharpening and the other for honing. Both stages utilize diamond abrasive surfaces so your blades will retain their edge for a long time.

This sharpener does an extraordinary job thanks mostly to the diamond abrasive wheels. You get an edge that’s both razor sharp and burr-free, as if you spent an hour working the edge on an oil stone. If people make a mistake with the 463, it’s that they assume more pressure is needed than is required. It really shines on serrated and straight-edged, double-bevel Asian-style knives.

Why trust us

A dull knife creates more work. They don’t produce clean cuts and can leave burrs and problematic shards in your food. I love to cook and make about 95% of my meals at home, so I need my knives sharp.

Who this is for

If you’re looking for a top-rated knife sharpener, this is the one-stop-shop. Whether you need to sharpen chef’s knives or your pocket knife, we have you covered.

How we picked

We focused on having a wide variety of products for all needs. We first consulted our testing team, then looked at best sellers and read hundreds of reviews.

Features to look for in knife sharpeners

Edge angle

Most kitchen knives are sharpened from 17° to 22° on each side. Most kitchen knives and chef’s knives sit in the 20° range, whereas Japanese knives should be 17° on each side. Larger, durable blades like hunting knives are in the 22° to 30° range.

Durability

Most knife sharpeners should last you between five to 15 years. In some cases, they can last a lifetime. You will want a durable product that does not quickly deteriorate or fall apart if dropped.

Functionality

When looking for the best knife sharpener, you will run into a couple of types of sharpeners. These include manual knife sharpeners, electric knife sharpeners, ceramic rods, and honing rods. Honing rods reshape the existing material to give a sharp edge. Sharpening slots and other types of knife sharpeners remove a layer of material and reshape the sharp straight edge.

Size

Generally, for a longer blade, you may need a longer manual or electric sharpener. However, most honing rods come in similar sizes.

Suitability

Your desired knife sharpener must be suitable for the job. For longer blades, you will need a correspondingly large knife sharpener, and for very sharp blades, hard abrasive material is necessary. The sharpening material of the knife sharpener should always be harder than the blade of your knife.

Safety

To prevent mishaps, safety is key. Most of the listed manual sharpeners are encased, which helps prevent direct harm to the body if the knife slips. When using sharpening steels or honing rods, make sure you always keep the knife pointed away from you.

Power and wattage

Since the sharpening process is under a minute long, electric knife sharpeners use very little power.

Knife sharpener FAQ

Q: How does a knife sharpener work?

The principle of a knife sharpener is very simple. Manual and electric sharpeners function similarly but one is electric. The abrasive material on the sharpening slot or sharpening stones must always be harder than the blade you wish to sharpen. If the knife is then treated with a sharpening steel, grindstone, or an electric sharpener, the abrasive material will cause the burr to reposition and align.

Q: Can I sharpen scissors with a knife sharpener?

It is not advisable to sharpen craft scissors or any other type of scissors with a knife sharpener, as you might end up with unwanted burrs and rough edges. It is better to purchase sharpeners made specifically for scissors.

Q: Do knife sharpeners cause damage to knives?

Damage can be prevented with the use of a quality knife sharpener. Additionally, it’s vital to avoid using knife sharpeners aggressively, especially those that are manually operated as some may cause the edges to chip off quickly. Creating a fine edge takes a gentle touch.

Q: How often can you use a knife sharpener?

Depending on the type of knife and how you use it, you can have your knives sharpened three to four times a year if you rarely use them. However, if used regularly, the right time to sharpen a knife is actually before each use. When sharpened regularly, you have a well-honed knife that never gets dull.

For most people, you can sharpen your knife as soon as it gets dull. Knives made from stainless steel or carbon steel usually require sharpening after every use.

Q: How do you know when it’s time to replace your knife sharpener?

The answer to this question depends on what kind of knife sharpener you own. A honing rod or honing steel should never need to be replaced, this type of device is moving the knife material to reshape it instead of removing material to create a sharp edge like a traditional manual sharpener. Knife-sharpening stones or whetstones may need to be replaced more often as they hollow out and create cracks. When you see damage to your whetstone or sharpener, it’s time to replace it. A diamond or ceramic honing rod should be replaced every five to 15 years, a knife-sharpening stone that lasts you a decade is an excellent deal.
