What experts didn't like
The ProntoPro 4643 can’t sharpen serrated blades, because it sharpens both sides of a blade at the same time, whereas serrated knives need sharpening on only one edge.

An Overview On Knife Sharpeners

Cooking at home has a slew of advantages for your waistline and your wallet. Making your own meals is far cheaper than ponying up for restaurant eats on a regular basis. Plus, you might shed some pounds if you’re in control of how much oil and fat you cook with.

However, you’ll need the right tools to mimic the delicious flavors you’d find in your favorite restaurant dishes. Quality knives are part of the foundation for a fully functional kitchen, but they can’t execute perfect slices if you don’t take proper care of them. A knife sharpener is a must-have for home cooks, but there’s some background information you’ll want to know before you pick one.

When you sharpen a knife, you remove minuscule amounts of metal from the knife to create a fresh, sharp blade. Sharpening your knife gives it a crisp edge, but it also wears your knife away since you’re removing material every time you sharpen it.

Keeping your knife’s blade straight is also crucial, and honing your knife in between sharpenings helps the knife last longer and cut more accurately. (Honing is an action that realigns the blade of an already sharp knife.)

There are many different kinds of knife sharpeners, but the most popular types are electric, manual and sharpening steels (also called honing rods). Electric sharpeners typically use a two or three-step process for creating, sharpening and honing your blade. Most electric sharpeners, like the Chef’sChoice Trizor Knife Sharpener, use guides to help you find the perfect angle. This is great for beginners, but more advanced cooks might prefer the manual control that comes with handheld sharpeners, like the Chef’sChoice Pronto Pro.

If you’re using a manual knife sharpener, you’ll place the sharpener on a flat surface and draw your knife through a sharpening slot. Models like PriorityChef’s Knife Sharpener use this design. Handheld sharpeners are less expensive than electric options, and they’re portable for chefs on the go.

Honing rods keep your blade properly aligned for better balance and precision while you slice and dice. They’re also referred to as sharpening steels, but that title is a bit of a misnomer since they don’t actually sharpen your knife. They’re still an essential component of your knife care system. A selection like Idahone’s Sharpening Rod uses a high-grade ceramic to re-align your knife’s edge.

Review Melt Fun Fact

The humble kitchen knife has fascinating, ancient origins. The oldest-known primitive stone tools were called “Oldowan knives” and they first appeared in modern-day Ethiopia about 2.5 million years ago. They were made by cracking rocks against each other to create sharp edges and helped our ancestors carve up horses, wild cattle, ducks and even rhinos.

The discovery of fire changed the way we made knives, allowing humans to form knives out of other materials other than large rocks. The copper and bronze ages added a tougher edge to kitchen knives, but the advent of iron and steel helped people craft knives that resemble what you’ll find in your kitchen today.

The Knife Sharpener Buying Guide

  • Before you buy, you’ll want to assess how serious you are about home cooking. If you’ve invested in pricey knives and see yourself whipping up new creations every day, a high-end electric sharpener like the Chef’sChoice Trizor Electric Sharpener is worth a look. If you just want to keep your knives sharp for a few casual meals per week, a budget-friendly buy, like PriorityChef’s Knife Sharpener, might be more your speed.
  • How much counter space do you have available for your knife sharpener? The Chef’sChoice Trizor Sharpener is a full foot long and weighs a hefty five pounds, while the Chef’sChoice ProntoPro is just over nine inches long and only weighs eight ounces.
  • Do you want a sharpener that shapes, sharpens and hones in one unit, or would you prefer a separate honing rod? The Chef’sChoice Trizor takes care of all three steps, while PriorityChef’s manual Knife Sharpener only shapes and sharpens. You’ll want to purchase a separate honing rod, like Idahone’s Fine Ceramic Sharpening Rod, if you purchase a two-step sharpener.   
  • How much mobility do you need in your knife sharpener? Electric options, like the Chef’sChoice Trizor, sharpen your knives in a snap, but they’re not road-friendly. If you have multiple homes or see yourself cooking on the road, a smaller manual sharpener, like PriorityChef’s Knife Sharpener, will easily fit into most bags.
