Best Knife Sharpeners – 8 Top Picks

I have to admit that this article arose out of a desire to finally understand how to choose the best knife sharpener when tackling the various EDC folding knives and kitchen knives used by our staff. Those are two very different applications, requiring very different types of knife sharpening. With tons of experience critically testing tools and a large array of experience with literally dozens of different pocket knives over the years, I have decades of combined experience to suss out the very best sharpeners for almost any application or user.

How to Choose a Knife Sharpener

When thinking about how to choose a knife sharpener, start with what kinds of knives you plan to sharpen. My recommendations differ between sharpening EDC folding knives vs honing kitchen knives. The desired application matters as does the metal composition of each blade.

In general, when sharpening very dull knives you want something specifically made to put a new or renewed edge on the blade. That entails either a good quality sharpening stone, diamond stone, or—at the very least—carbide blades. For the task of putting on a new edge, you also want to ensure you have a good level of consistency. If your system lets you vary the angle because it relies on your grip or hand position, you could end up working against yourself with every other stroke. Something with a solid angle guide should speed up the process.

If you tend to keep up with knife sharpening, then simply having a good-quality ceramic sharpener might be all that you need. A few passes regularly with that kind of system lets you maintain a nice edge for many years.

What About Serrated Blades?

One last consideration—aside from your budget, of course—is the sharpening of serrated blades. Not every sharpening system accommodates those blades—and not all serrated blades are the same. Whether you need a pull-through solution or a stone sharpening system, be certain your sharpener is designed to keep these blades in tip-top shape.

Best Knife Sharpener Overall

Work Sharp Professional Precision Adjust Knife Sharpener

Work Sharp Professional Precision Adjust


  • Excellent construction
  • Enough flexibility to sharpen nearly any knife (even serrated)
  • Replaceable magnetic sharpening stones


  • Expensive

Having used the Lansky knife sharpening system for years, Work Sharp takes everything great about that system and improves it. While not inexpensive, the Work Sharp Professional Precision sharpener features metal construction. Of particular note, the articulating hinge point is metal—the part that arguably suffers the most abuse during use. You can adjust the system from 15 to 30 degrees using a simple adjustment knob. On top of that, Work Sharp gives you a digital angle finder for even better precision.

While Work Sharp also makes electric sharpeners like their Ken Onion Edition, I prefer the less aggressive manual sharpener as it produces a much better and much more consistent result. Note: If you want to risk plastic construction and a weaker hinge point, check out the Work Sharp Precision Adjust Knife Sharpener which has many of the same core features but at a savings of nearly $200!

Verdict: The most flexible sharpening system guaranteed to give you an excellent edge every time


  • Grits: 220, 320, 400, 600, 800 (diamond), fine ceramic, and leather strop
  • Includes: Metal sharpening frame, table attachment, digital angle indicator, seven 1×6 sharpening abrasives, ceramic rod, leather strop, metal V-clamp, clamp stabilizer
  • Price: $249.99

Best Knife Sharpener for the Money

Smith’s PP1 Pocket Pal Knife Sharpener

Smiths PP1 Pocket Pal


  • Super-portable
  • Tackles serrated blades


  • Only one angle option for sharpening your knives

You can find a lot of inexpensive solutions for portable knife sharpening. I tend to lean into those that work well for pocket knives as opposed to tabletop kitchen knife sharpeners. Smith’s PP1 Pocket Pal Knife Sharpener gives you a very simple, travel solution for sharpening even the dullest knives. I like the independent coarse/fine carbide/ceramic grooves as well as the fold-out diamond-coated rod for dealing with serrated blades. If you want something to take camping, leave it in your glove box, or just about anywhere you may run into a need to care for a dull blade.

I also love the design of this tool. Where some require you to (dangerously in our opinion) hold the sharpener in your hand, the flat bottom of the PP1 lets you sit it securely on a table while you pull away from the sharpener. Note: Pull-through sharpeners wreak havoc on the actual blade edge. Use a more expensive flat stone sharpening system for the best results and the long-term health of your blades.

Verdict: Take this $10 sharpening tool with you anywhere, but avoid using it on more expensive blades where you want a truly perfect edge.


  • Model: PP1
  • Grits: coarse (carbide) and fine (ceramic) plus tapered diamond rod
  • Includes: All-in-one sharpener
  • Price: $9.77

Best Pocket Knife Sharpener

Lansky Professional Knife Sharpening System

Lansky Professional Knife Sharpening System


  • Supports a wide array of angles (17–30 degrees)
  • Even wear over time


  • A more manual sharpening method that takes more time and technique

If you merely want to focus on pocket knives, then you can forgo systems that cater to longer chef’s knives and other lengthy blades. This can save you money, and you can focus on tools that cater to the sharpening angles most typically found in folding pocket knives. I think the best pocket knife sharpener still has to be the Lansky Professional Knife Sharpening System. While not necessarily as easy to use as some others, it gives you the flexibility to tackle any knife edge. It also provides the flexibility to handle all blade angles and includes everything you need except a leather strop (which I recommend adding!)

Verdict: Using this system makes you feel like a Pro and gets professional results


  • Model: LKCPR
  • Grits: 120, 280, 600, and 1000 grit stones plus medium grit serrated knife sharpener
  • Includes: Clamp and angle holder, 5 extension rods, 5 sharpening/honing stones, honing oil, case
  • Price: $51.78 (often less)

Best Electric Knife Sharpener for Kitchen Knives

Chef’sChoice Trizor 15XV Professional Electric Knife Sharpener

ChefsChoice Trizor 15XV Professional Electric Knife Sharpener


  • Truly carefree sharpening
  • Supports serrated blades


  • Expensive
  • Loud during use
  • No scissors sharpening
  • Leaves a rougher edge than stone-based sharpeners

If you want a much speedier method of sharpening all of your kitchen knives, the ChefsChoice Trizor 15XV Professional Electric Knife Sharpener does an amazing job. While certainly not as quiet as a manual sharpener, you gain the advantage of being able to cruise through sharpening a dozen knives in less than 15 minutes. The Trizor 15XV features a three-stage sharpening system (sharpen, hone, polish). It takes up just 10 inches of width on your counter—but I recommend storing it underneath in a cabinet and just pulling it out when you need to sharpen a knife or two.

What really makes this system stand out are the guides. The sharpener automatically guides your knife through the sharpening process. For those new to sharpening, this means you don’t have to develop a technique or hold the knife exactly at the perfect angle. The system automatically presses the blade against the plastic guide to hold the perfect angle. The course grind also has enough oomph to rehone your blade to 15 degrees if it has a slightly shallower grind to begin with. Another advantage of this system is that you can use the polish (third) slot for serrated blades.

Verdict: A truly quick and idiot-proof kitchen knife sharpener for anyone


  • Model: 15XV
  • Grits: diamond abrasives for course, hone, and polish
  • Sound: 65-75 dBA
  • Price: $179.95 (often less)

Best Manual Knife Sharpener for Kitchen Knives

Smith’s 50146 Stainless Adjustable Angle Knife Sharpener

Smith's 50146 Stainless Adjustable Angle Knife Sharpener


  • Adjustable sharpening angle
  • Stainless steel design


  • Not suitable for most serrated blades
  • Not recommended for expensive blades

With possibly the most helpful feature I’ve seen, the Smith’s 50146 Adjustable Angle Knife Sharpener gives you a way to dial in angles from 14 to 24 degrees. That makes it perfect for paring or chef’s knives. It even handles serrated blades with the help of a fixed blade. Smith’s makes a plastic version of this, but I prefer the stainless model.

Verdict: The only knife sharpener you need for your non-serrated kitchen knives


  • Model: 50146
  • Grits: Coarse (carbide) and fine (ceramic) plus fixed angle serrated
  • Includes: All-in-one adjustable sharpener
  • Price: $35.72 (often less)

Best Serrated Knife Sharpener

Lanksy Blademedic 4-in-1 Knife Sharpener

Lanksy Blademedic 4-in-1 Knife Sharpener


  • Single solution for serrated and non-serrated blades


  • None

While many blade sharpeners claim to work by drawing the serrated edges past a set of honing blades, I prefer a manual draw-through sharpener. However, why not combine that with a decent handheld sharpener that also does smooth blades? The Lanksy Blademedic 4-in-1 Knife Sharpener presents an excellent solution for both. I like the fold-out tungsten-carbide draw-through sharpener and the carbide and ceramic sharpeners also do excellent for sharpening and honing regular blades.

Verdict: Take it with you anywhere for any type of blade


  • Model: PS-MED01
  • Grits: Coarse (carbide) and fine (ceramic) plus serrated ceramic and draw-through diamond-tapered
  • Price: $15.22

Best Ceramic Knife Sharpener and Scissors Sharpener

Smith’s 50185 Jiffy-Pro Handheld Sharpener

Smiths 50185 Jiffy-Pro Handheld Sharpener


  • All-in-one inexpensive solution
  • Hones blades and sharpens scissors


  • Plastic construction

Sometimes you come across a solution that really excels at more than one task. That’s the case with the Smith’s 50185 Jiffy-Pro Handheld Sharpener. It has a nice ergonomic grip for fine ceramic sharpening, but the tool also lets you sharpen scissors more easily than most. Stand the tool upright and you can insert a pair of scissors from either side depending upon which blade you want to sharpen. I don’t think it does the best at sharpening a truly dull blade, but in a pinch, it can get you back up and operating. For honing a reasonably sharp blade, however, it does very well.

Verdict: Best for quickly honing or deburring blades of all types plus sharpening scissors


  • Model: 50185
  • Grits: Coarse (carbide) and fine (ceramic) plus scissors
  • Price: $21.54

Best Whetstone Sharpener for Knives

Intelitopia Complete Whetstone Knife Sharpening Set

Intelitopia Complete whetstone knife sharpening set


  • Straightforward sharpening process
  • Includes strop and angle guide


  • Prep required for stones
  • Requires a consistent angle to get a perfect edge

You can choose to pay more for a DMT sharpening kit—and I used to—however, the Intelitopia Complete Whetstone Knife Sharpening Set includes everything you need for taking care of most non-serrated blades. I particularly like the dual-sided 400/1000 and 3000/8000 grit blocks coupled with the bamboo base. You also get a leather strop for finishing your edge as well as a course flattening stone to reset your aluminum oxide sharpening stones back to flat. Finally, for those who don’t know how to use a whetstone, you get a handy instruction manual that walks you through the entire process along with a handy angle guide.

Verdict: My go-to sharpener for larger fixed-blade knives


  • Model: MDS00A
  • Grits: 400/1000 and 3000/8000
  • Includes: Bamboo base w/silicone holder, 2X aluminum oxide sharpening stones, flattening stone, leather strop, angle guide
  • Price: $36.99

Other Knife Sharpeners from Trusted Brands

Work Sharp Ken Onion Knife & Tool Sharpening System

I enjoyed using the Work Sharp Ken Onion Knife & Tool Sharpener Field Kit. While, by far, the quickest sharpening system of all the ones I’ve tested, it didn’t make my top list due to the learning curve and how much material it tends to take off the blade. You also have to go through a process to swap out the abrasive belts to go from one grit to another—a process that, while not difficult, slows down the process considerably. Lastly, by its nature, the Work Sharp puts a convex edge on your knives as opposed to the other systems I use that produce a flat grind.

  • Pros: Supports 15–30 degree angles; fast sharpening
  • Cons: Removes lots of material, creates a convex edge, requires belt changes
  • Verdict: I love the sheer speed of sharpening this system affords


  • Model: WSKTS-KO
  • Grits: P120 Extra Coarse, X65 Coarse, X22 Medium, X4 Fine, 6000 Extra Fine
  • Includes: Sharpener, 5 pc belt kit, adjustable guide, DVD, soft bag
  • Price: $139.95

DMT Deluxe Diamond Knife Sharpening 3-pc Kit

Made-in-the-USA DMT offers similar performance to my Intelitopia recommendation above but gives you diamond technology. No honing oil is needed. You can wet the stone or use it dry (I prefer soaking the stones first). The Deluxe kit includes Coarse, Fine, and Extra-Fine stones in a wooden box. This is a great sharpening system and an even better gift!

  • Pros: Supports 15–30 degree angles; fast sharpening
  • Cons: Removes lots of material, creates a convex edge, requires belt changes
  • Verdict: I love the sheer speed of sharpening this system affords


  • Model: 20062
  • Grits: P120 Extra Coarse, X65 Coarse, X22 Medium, X4 Fine, 6000 Extra Fine
  • Includes: Sharpener, 5 pc belt kit, adjustable guide, DVD, soft bag
  • Price: $89.89

Frequently Asked Questions

Do Knife Sharpeners Really Work?

Absolutely! Regardless of what type of sharpener you use, you’ll quickly find that you can take an underperforming blade and make it as good as new. Factors that affect whether a blade sharpens well have more to do with the style of steel in the blade itself and whether or not you follow a proper technique when honing the blade. Also, keep in mind that the level of dullness on the blade should determine the grit or level of sharpening you should do when getting it back to pristine cutting condition.

If you truly value your blades and have an expensive knife, you want to favor a flat stone over a pull-through sharpener. The former delivers a smooth, perfect edge while the latter leaves rough edges when viewed through a microscope. Over time. a pull-through sharpener can continuously damage a blade’s edge. You can get a lot of life off a cheap kitchen knife using these types of sharpeners, but you may not want to do that with an expensive blade. In any case, you can always correct a blade’s edge by periodically giving it a more thorough sharpening with a flat stone system.

Which Knife Sharpener Works Best for Fillet Knives?

Fillet knives require a much steeper 15- to 20-degree blade angle. Asian-style knives tend toward 15 degrees with their American counterparts often manufactured to the 20-degree angle. In either case, you want to ensure your knife sharpener supports this shallower angle so that you can keep that nice filleting edge on your blade. Expect to sharpen these knives more frequently to ensure consistent performance.

What Knife Sharpener Does Gordan Ramsey Use?

We can’t speak to what sharpener he always uses, but if you look closely at a video posted to his Youtube account on December 17, 2013, he demonstrates his sharpening technique using what appears to be a Friedr Herder 12-inch 1/2″ Round Sharpening Steel. The current model for this can be found here and runs about $39 before shipping. As you can imagine, Gordan has really honed his technique over the past several decades (pun intended!)

Some Additional Thoughts

Knife sharpening is part craft, part technique, part efficiency, and part passion. When you add those up and tack on your own preferences, I’m certain you can choose something off this list and have great success. The bottom line? If you want to keep your knives sharp, lots of excellent systems exist to help you do that. What surprised me was just how affordable many of these solutions are. In the end, you may end up wanting to purchase more than one to take care of your personal knife collection.
