Spyderco Knife Sharpeners Review: Does It Make the Cut?

Sharpening a knife is a key skill in any kitchen. A sharp knife is safer and saves you valuable prep time. If you’re looking for a sharpener for your kitchen, a Spyderco knife sharpener may be a good starting point.

Spyderco has been making knives and sharpeners for 40 years. Their products are simple and efficient. If you’re looking for a way to keep your edge in the kitchen, Spyderco could make the job easier.

As with any other kitchen utensil, you need to pick the best one for you. If you regularly sharpen knives, a knife sharpening system has to be the best.

These leave the guesswork out of sharpening for a quick and refined edge. It’s true that Spyderco has many sharpeners to choose from, but are they the best? Let’s see how they stand up to the competition.

What Is Spyderco?

Spyderco originated in 1976. Gail and Sal Glesser, a couple based in Golden, Colorado, started by selling their signature knife sharpener at trade shows.

The original Spyderco knife sharpener, the Tri-Angle Sharpmaker, is still their flagship product today. They soon went on to start making knives as well.

Their first folding knife introduced features that came to define what makes a folding knife.

Now, Spyderco offers a massive variety of knives and other related products. Their main website includes not only a store but a forum, educational material, and extensive resources. They have built a community around their knives and knife sharpeners.

What Stands out with a Spyderco Knife Sharpener

Spyderco wouldn’t be able to build a community around their products if they weren’t special. The Tri-Angle Sharpmaker, their first product, is certainly unique even in appearance.

The Sharpmaker is, at its core, a black block with slots in it. To use it, you place ceramic whetstones into the appropriate slots and draw the knife across them. It stands out from other sharpeners by taking the guesswork out of sharpening.

When sharpening a knife, it is important to keep the blade at a consistent angle. That will make the edge of the blade even and allow it to cut more sharply.

The Tri-Angle Sharpmaker holds the whetstones at an even 15 or 20-degree angle, depending on your settings. With set angles, it’s much easier for anyone to sharpen their knives properly.

The Sharpmaker also comes with a set of brass rods that act as handguards, letting you sharpen safely.

Bench stones, ceramic files, and pocket stones

Of course, the Tri-Angle Sharpmaker is not the only Spyderco knife sharpener. Spyderco has a wide array of sharpeners to fit your kitchen.

For a more practiced knife sharpener, you have the option of using a bench stone or sharpening stone. It’s a flat stone which holds a grit, much like sandpaper.

You use coarser grits to hone dull blades. After this, a finer grit refines the edge. Most whetstones do require you soak them thoroughly before use.

But that is not necessary for a Spyderco knife sharpener. Using a bench stone like this requires more dexterity. You have to hold the knife at the angle you desire as you sharpen.

Spyderco knife sharpeners come in a variety of shapes and sizes. They also include ceramic files that provide specified precision for craftsmen.

The various shapes are useful for filing and sharpening objects usually found outside of the kitchen.

One can say the same for Spyderco’s pocket stones. You can easily transport these small whetstones and use them on knives and tools outside of the kitchen. One such stone that is unique; however, is the Golden Stone.

This fan-shaped stone lets you easily sharpen knives at a 20-degree angle. Its various contours make it useful for kitchen shears, serrated knives, and other cooking utensils.

And, its small size means you can use it anywhere. Storage won’t be a problem, even in kitchens with limited space.

What reviewers say

A product doesn’t exist for over 40 years without earning its longevity. Reviewers for the Tri-Angle Sharpmaker are of the consensus that this product has definitely done so.

The Sharpmaker is “something of a legend” on Blade Guru. At Knife Informer, they say that it’s one of the best sharpening systems available.

In fact, they say that many of their knife experts prefer it to a single stone. Customers on Amazon were similarly positive. Of 2,014 reviewers, 79 percent gave the Tri-Angle Sharpmaker 5.0 out of 5 stars.


A Spyderco knife sharpener that had kitchen applications will run at least around $70 to $90 on the Spyderco website.

The flagship Tri-Angle Sharpmaker costs between $100 and $120. For one bench stone, you may expect to pay from $69.95 to $89.95.

Since a proper sharpening requires both coarse and fine sharpening stones, you may end up paying over $150 for two stones.

The Golden Stone’s price is between $100 and $110. These products are available at a significant price cut elsewhere. You can buy the Sharpmaker for around $60 to $70 at Amazon and Blade HQ. The Golden Stone is between $80 to $90 on Amazon.

For any sharpening experience, you may want, you can find a Spyderco knife sharpener at a competitive price.

Sizing Up Spyderco Knife Sharpeners

Sizing Up Spyderco Knife Sharpeners

We’ve established that Spyderco makes excellent products, including the Tri-Angle Sharpmaker. But how do they shape up to other competition?

A few selected knife sharpening sets have been included to see how they compete with a Spyderco knife sharpener.

Among the competition are the Skerper Basic Set, the Work Sharp Multi-Sharpener (Ken Onion Edition), Naniwa Professional Whetstones, and the Lansky De Luxe Sharpening System.

How we reviewed

We looked at reviews from a combination of sources. Sharpeners and sharpener sets were selected based on best-of lists from sources such as Knives and Tools.

We included them for their versatility and price. The sharpeners included here are listed in order of lowest listed price.

Lansky De Luxe sharpening system

No products found.

The Lansky De Luxe sharpening system has been around almost as long as the Tri-Angle Sharpmaker. It uses a unique system involving a rod and clamp, where you swipe the whetstone across the blade as opposed to the other way around.

The De Luxe system includes five different sharpening stone grits, giving you a wide range of control. It also allows you to set the sharpener at a wider range of angles than the Tri-Angle Sharpmaker. One area where the Knife Informer review found difficulty was in the setup.

The reviewer warned that anything that might affect the accuracy of the system would result in an unsatisfactory result. For them, these all had easy fixes. Amazon reviewers rated it 4.3 out of 5 stars.

Skerper Basic sharpening set with sharpening steel

The Skerper Basic sharpening set brings a good range of whetstones for a budget price. The Skerper Basic set gives users four different grit stones.

With four stones, even the dullest knife can be sharpened gradually up to a perfect edge. Skerper stones require a thorough soaking beforehand and are a low-cost introduction to flat-stone sharpening.

Included in the set is a ceramic sharpening rod which helps keep knives sharp and straight.

Regular use of the sharpening rod would limit the need to use the stones, extending their usefulness. Consumer reviewers on the Skerper website gave the Basic set 5.0 stars out of 5.

Work Sharp Ken Onion Edition knife and tool sharpener

No products found.

At first glance, the Work Sharp knife and tool sharpener looks like a power tool.

In a sense, it is, working similarly to a belt sander. Rather than a set of stones, the Work Sharp uses a set of five belts. These belts work the same way as the stones do.

The only difference is, you don’t have to sharpen by hand. The sharpener allows you to set the angle as well. You can set it anywhere from 15 to 30 degrees.

The Knife and Tool Sharpener takes the guesswork out of sharpening; By allowing the angle settings and belt sharpener to do the work for you, you can put a precise edge on your blade in no time.

Amazon reviewers gave the Work Sharp Ken Onion Edition knife and tool sharpener 4.6 stars out of 5.

Naniwa professional stones

No products found.

Naniwa offers bench stones similar to those offered by Spyderco. They range in grits from 400 to 5000, finer than most stones available.

Knifewear explains that Naniwa stones are much more abrasive than other lower-quality stones. With these stones, you can sharpen a knife in fewer swipes.

However, they do require you to learn to sharpen a knife on a flat whetstone, which requires more skill. The price of one stone can range from around $40 to over $100 for the finest grits.

On Knives and Tools, a set of whetstones is available for around $225 to $240. The 800 grit Naniwa stone was rated 4.8 out of 5 stars on Amazon.

Pros and Cons of Spyderco Knife Sharpeners

As renowned as Spyderco knife sharpeners are, especially their trademark Tri-Angle Sharpmaker, they may not be right for every kitchen. Here’s why they work, and why they might not.


  • Angled stones make sharpening easy
  • Low price for high quality
  • Very safe to use
  • Long-lasting design


  • Need to purchase additional stones for other grits
  • Only two angles available for grinds
  • Slight room for error when sharpening

Which Sharpener Belongs In Your Kitchen

A knife sharpener can be an excellent addition to any kitchen. With practice and care, regular sharpening will extend the life of your knives. It can also save you money on trips to a professional.

It’s worth noting that if you’ve never sharpened a knife before, you may want to get yours professionally sharpened first.

A Spyderco knife sharpener is as good an addition to your kitchen as any. The Tri-Angle Sharpmaker is even better. With 40 years of reputation under its belt, and for under $100, it is a standby for both knife experts and amateurs.

If you want a Spyderco knife sharpener which will help you master your sharpening skills, consider a bench stone. Spyderco’s are comparable in price to other flat whetstones.

However, they take a little time off the process. By not needing to lubricate your stone, you can sharpen without worrying about damaging your knife.

All in all, you can rest assured that a Spyderco knife sharpener has been engineered to ensure an easy experience.

That’s true whether you’re using the Golden Stone or a more skillful bench stone. Four decades of experience at Spyderco come together to make products that help you sharpen your knife simply and effectively.
