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 every time. While this is a “2-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.
For this type of handheld manual sharpener the 463 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 actually is. Keep in mind though that it really shines on serrated and straight-edged, double bevel Asian-style knives.

I love to cook and make about 95% of my meals at home, meaning I like my knives sharp as they are my best friend in the kitchen.
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, what feels like the dullest blades on earth, or your pocket knife needs a tune-up, we've got you covered. Professional chefs might have their tried true favorites and see less need for this guide. However, for the rest of us, it's likely you'll find an ideal product here.
How We Picked
Selecting the best knife sharpener is no easy feat and is often dependent on the knife angle, material, personal needs, and more. When curating this guide, 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 to bring you the best options to sharpen knives.
Features To Look For In A Knife Sharpener
Edge angle - Most kitchen knives are sharpened from 17 to 22 degrees on each side, creating a 40-degree angle total, give or take. Most kitchen knives and chef's knives sit at the 20-degree range, whereas Japanese knives should be 17 degrees on each side. Larger, durable blades like hunting knives are in the 22 degree to 30 degree range.
Durability - Most knife sharpeners should last you 5 to 15 years, and in some cases, a lifetime. You will want a durable product that does not quickly deteriorate or fall apart if dropped or bumped.
Functionality - When looking for the best knife sharpener, you will run into a couple of types of sharpeners. These include a manual knife sharpener, an electric knife sharpener, ceramic rods or honing rods. Honing rods and some honing devices 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, a hard abrasive material is necessary. Generally, the sharpening material of the knife sharpener should always be harder than the blades of your knife.
Safety - To prevent mishaps with your sharpener or knife's blade, 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 so a little slip doesn't create a big ouch.
Power and wattage - Although many household appliances are known to consume a lot of energy, since the sharpening process is under a minute long, the electric knife sharpeners we have listed here use very little power to produce a very sharp edge and therefore won't run up your electricity bill.
Knife Sharpener FAQ
Q: How does a knife sharpener work?
A: The principle of a knife sharpener is very simple. There are different materials that are suitable for sharpening knives. Manual and electric sharpeners function similarly but one is well, you know, electric. The abrasive material on the sharpening slot or sharpening stones must always be harder than the dull blade in question to be ground. 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?
A: 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 and their particular blade edge.
Q: Do knife sharpeners cause damage to knives?
A: 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?
A: 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. But it's also enough if you sharpen your knife as soon as it gets dull. Knives made from stainless steel or carbon steel usually require sharpening after every use. If you need to cut raw meats or other tricky items where you need to cleanly slice and cut, sharpen your knife before laying into the fish or meat.
Q: How do you know when it's time to replace your knife sharpener?
A: 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 replaced it. A diamond or ceramic honing rod should be replaced every 5-15 years, a knife sharpening stone that lasts you a decade is an excellent deal.
