"Steels are an inexpensive, easy way to keep your knives in shape between sharpenings."

A good knife is a sharp knife, but you don’t need to have them professionally sharpened. The worst feeling is to have all the vegetables cleaned, ready to be chopped for some delicious homemade soup stock, and finding your knife is not up to the job. 

Many knife sets come with a honing steel. This is not a tool for sharpening. When you sharpen a knife, it shaves some of the metal to restore the blade’s edge, and can even reshape a blade from a Western-style 20-degree edge to a sleeker Asian-style 15-degree. While you should hone your knives often, sharpening should be done a few times per year. A steel does not shave metal off your knife, rather it realigns the blade’s edge to render it sharp for each use. If you maintain a steady routine of honing, and sharpen your knives occasionally, you will never be left on Thanksgiving trying to slice through a tough butternut squash with a dull blade. Regular honing and sharpening also keeps you safe since a dull knife can be dangerous. The blunter your blade, the more pressure you must put on to make the cut, increasing your chances of injuring yourself in the process. 

If you want to check your blades for sharpness, there is a quick at-home test that does not involve running your finger along the knife’s edge. Hold a piece of paper with your thumb and forefinger. With your other hand, use your knife to cut into the side at an angle. Sharp blades make a clean cut through the paper. If your paper remains intact, it is time to get out the sharpener.

From a set of versatile sharpening stones to a diamond abrasive electric station, here are the best knife sharpeners.

Best Overall: Chef’sChoice 15 Trizor XV EdgeSelect Professional Electric Knife Sharpener

When you are looking for a tool to reshape, sharpen, and polish your knives, the Chef’s Choice Trizor XV is up to the challenge. It has a slot for honing, a slot for sharpening, and a slot for polishing. The three stages incorporate two 100-percent diamond abrasives for coarse or fine sharpening, and a flexible abrasive system for stropping—the final stage of sharpening where microscopic-level inconsistencies of the edge are removed to ensure a razor-like edge. Stage three can also sharpen your serrated knives with conforming grooves to grab the serrated edges.

If it only had these functions, it would be a great addition to your kitchen, but it also can convert Western-style, 20-degree angles to slim, Asian-style 15-degree angles. Western-style edges are heavier, and built for tougher chopping, while Asian-style edges are known for handling precision tasks like mincing parsley and slicing tomatoes with ease.

The Trizor XV is easy-to-use with its slot guides to ensure your knife is at the right angle and not slipping around. It has a simple on/off switch, and sharpens knives from end-to-end in minutes. 

Best Budget: KitchenIQ 50009 Edge Grip 2-Stage Knife Sharpener

kitcheniq-edge-grip-knife-sharpener

It is hard to believe something this diminutive in stature and price could be effective, but it is. The KitchenIQ Edge Grip features two sharpening options: coarse and fine. The coarse mode has carbide blades for when you’re after that sharp edge, especially useful when you have a dull knife that needs rehabbing. The fine option has ceramic rods that hone edges between full sharpening. 

The KitchenIQ works on both serrated and straight-edge knives, a bonus for a manual sharpener. It has a non-slip base for stability and an edge grip, which allows you to sharpen on the edge of a table or countertop, preventing scratches to your surfaces. It also comes in a variety of fun colors to brighten up your kitchen. It is a compact, affordable choice that gets your knives sharp.

Best Electric: Chef’sChoice 130 Professional Electric Knife Sharpening Station

chefschoice-electric-knife-sharpening-station

If you are not interested in converting your 20-degree knives, this is a better choice than the Trizor XV. It is a workhorse for Western-style knives. Its electric three-stage system starts with a 100-percent diamond sharpener, then a super-hardened steel sharpener, and lastly, flexible stropping disks. There are built-in guides for ease of use, and ensuring consistently sharp edges. 

The versatile Chef’s Choice 130 can be used on both straight edge and serrated knives. It is not just reserved for kitchen knives either—you can sharpen your household, sports, and pocket knives as well. Its stabilizing rubber feet grip the counter and keep the unit secure. It quickly brings your knives back to factory-quality, razor-sharp performance.

Best Manual: Priority Chef Knife Sharpener for Straight and Serrated Knives

If you have a cozy kitchen, the Priority Chef Knife Sharpener will not take up much real estate. It has a non-slip base that keeps it secure during sharpening, and also protects countertops from scratches that could happen while in use. There are two sharpening slots. One has a coarse diamond coating for sharpening, and the other has a ceramic wheel for honing and improving any microscopic imperfections.

Manual sharpeners tend to be easier to use, and this Priority Chef is no exception. There are no settings to learn or mechanized processes to understand. You just grip the handle and swipe your blade through. The sharpener works on serrated blades as well, but the manufacturer cautions to only use the honing slot for them.  

This budget-friendly, space-saving option also makes a great choice on road trips, and at vacation rentals to ensure you have a sharp blade for that chopped salad.

Best Sharpening Stone: Lansky Deluxe 5-Stone Sharpening System

Lansky Deluxe 5-Stone Sharpening System

As a knife enthusiast, this whetstone set speaks to me. It has five different, color-coded to their grit level sharpening stones, and they have little finger grips to secure your hold. It gives you ultimate control over angles and allows you to sharpen with precision. 

Whetstone, or sharpening stone, comes from the word “whet” which means to sharpen. They provide a superior result sharpening and retaining a razor-like edge, but they also come with a learning curve. This set is not immune. Sharpening on whetstone requires practice, but once you nail the technique, it can be addictive. You will be sharpening everything from butcher knives to hunting knives, and this set can handle that obsession. 

The set also comes with some added safety with its guide rods and knife clamp, unlike traditional whetstones where you freehold the stone and the knife. The only caveat, other than the learning curve, is the smallest guide is 17-degrees, so if you have Asian-style knives you will have to sharpen without the guide rods, but this takes a steady hand. 

Best Versatile Sharpener: Work Sharp Culinary E5 Kitchen Knife Sharpener with Ceramic Honing Rod

Crafting knives often involves some time with a belt for shaping, smoothing, and polishing the blade. The Work Sharp utilizes flexible sharpening belts to create factory-sharp edges. Belts are less harsh than diamond-studded abrasives, but still very efficient, and easier on your knives in the long run. 

The Work Sharp comes with nine belts in three different grit levels that run on three settings: shape, sharpen, and hone. The sharpener automatically turns itself off at the end of the chosen setting, preserving your blades from being oversharpened. There is an integrated vacuum that sucks the debris during the process to keep the mess at bay. It also boasts the ability to sharpen any knife from luxury steels to basic cutlery, from serrated to straight-edged.

It is easy to use with just one power setting, a timer for controlled operation, and can be used electrically or manually (the middle slot is for the manual option). It has guides for different angles, but not one to accommodate a 15-degree knife, like a santoku. For angles that slim, you must sharpen without a guide, which takes practice.

The Work Sharp comes with a ceramic honing rod to straighten knives between sharpening, an important tool for your kitchen collection. A belt system can be a bit of a learning curve, but the end result is worth the time. 

Best Sharpening Steel: Wusthof 10-Inch Sharpening Steel with Loop

Wüsthof - 10" Knife Sharpening Steel with Loop

This steel does not technically sharpen your knives—it straightens the edge of the blade that gets bent during use. The bending is not visible, but you can tell when your knife seems dull that it needs some honing. Steels are also an inexpensive, easy way to keep your knives in shape between sharpenings.

The Wüsthof comes with a loop for hanging and an ergonomically designed, slip-resistant handle that is comfortable to grip. I own this steel and love it. It is magnetic, so it collects all the metal fiber dust that comes off the knife while honing, and it conveniently hangs beside my knife rack. I would never consider a sharpening setup complete without a honing steel. Sharpeners are important a few times per year to prolong the life of your knives; steels are necessary almost daily to keep your appendages safe from the hazards of dull blades.

Final Verdict

If you are looking to equip your kitchen with a tool that can not only sharpen and polish your knives but also convert them from 20-degree blades to 15-degree blades, we recommend the Chef'sChoice Trizor XV (view at Amazon). If you want to try a manual sharpener that offers compact storage, control, and versatility choose the Lansky Deluxe (view at Amazon).
