Top 10 Best Pocket Knife Sharpeners for Multi-Tools and EDC

1.Work Sharp Pocket Knife Sharpener | Ken Onion Edition

Ken Onion Edition by work sharp

Work Sharp developed this sharpener to help maintain the edge on every type of folding knife quickly and conveniently. It’s loaded with amazing features, including an adjustable guide to help you get the precise and consistent bevel angle on your knives.

Whether it’s from an angle of 15 or 30 degrees, sharpening knives is a breeze with this little tool. It’s great for knives of any size, shape, and type. This sharpener also features abrasive five belts with different ranges of grits to handle various tasks, from grinding to polishing an edge.

For even better results, this sharpener comes with a variable speed motor that lets you increase or decrease the speed or make each stroke more precise. That makes it the best knife sharpener out there if you’re looking for control and accuracy.

Another reason to love this product is its versatility. It isn’t just a sharpener for a pocket knife; it can also handle other sharp tools. It also works fine on scissors and garden tools, such as axes and shovels.

sharpening different types of knives

Given the fact that this sharpener has an adjustable guide, plus a speed motor, it’s better to watch YouTube videos about how to use it before getting started. The instruction manual is useful, but nothing compares to seeing it in action. If possible, practice with a cheap knife first.

One of the most notable features of this Ken Onion knife sharpener is that it can reliably create a smooth convex edge – but what does this mean exactly?

adjustable angle guide

A convex edge is slightly rounded and more tapered than a factory-made edge. A blade sharpened in this way is often considered to be more durable than store-bought knives, it’s also considered to provide a much smoother cutting experience.

Compared to other Work Sharp products, this edition is a bit heavier because of the larger-speed motor and cast metal components. Despite the added weight, it does the job exceptionally well.

Key Features

  • The Ken Onion name is stylishly featured on the handle of the knife sharpener.
  • The 3/4 x 12-inch belts are wider and larger than your average knife sharpener, and they’re also very durable.
  • The flexible belt design lets you sharpen most types of knives with ease, control, and precision.

2. Spyderco Tri-Angle Premium Sharpmaker Set

Spyderco Tri-Angle Premium Sharpmaker Set

If you’re looking for a small yet effective pocket knife sharpener, this tool is one of your best options. It’s composed of two sets of ceramic stones: a rough one for heavy-duty aggressive sharpening and a fine surface for high-grade finishing.

The stones are triangular in shape, making it easy to use on pocket knives with either plain or serrated edges. Once the job is done, you can tuck everything away in the neat carrying case.

This pocket knife sharpener comes in an ABS plastic base that features die-cut slots and holes fitted for the stones. You can use it to measure the stones’ sharpening angles, which can be anywhere from 30 degrees (15 degrees each side) or 40 (20 degrees each side). To keep you from accidentally cutting your hands, the system comes with brass rods for protection.

Another reason it makes our list of the best pocket knife sharpeners is that it works very well for smaller blades that are too difficult to clamp in a honing vise. You can also use it without water, oil, or lubricants.

Key Features

  • All parts can snap back into the self-contained plastic base and lid.
  • The packaging includes an instruction book and DVD for the step-by-step process of sharpening pocket knives, scissors, and other cutting tools.

3. Smith’s 50982 Pocket Pal Knife Sharpener

Smith's Abrasives PP1 hunting folding knife sharpener

This is a lightweight and portable product manufactured by Smith’s, a fast-growing supplier of knife and scissor sharpeners from Arkansas. Given the brand’s reputation, you can expect this tool to give your blade a sharp edge, no matter where you are.

Compared to Spyderco Tri-Angle Premium Sharpmaker Set, this pocket knife sharpener is smaller, which is perfect for the outdoorsy type. It measures 3.5 inches long and 1 inch wide and weighs only 1 ounce. You can simply put it inside your pocket and forget it’s there.

The coarse carbide blades sharpen dull or damaged edges quickly while the ceramic sharpening stones are great for finishing the job. The stones have 800 grit and give blades a smooth, polished edge.

This sharpener also features a fold-out tapered diamond rod with 400 grit. It’s great for sharpening both standard and serrated edges. Considering its portability and functionality, this product is one of the best sharpeners you’ll ever purchase – it also helps that it has a lower price point.

As with most sharpeners, always remember that this product will require a bit of maintenance. Clean it with a damp cloth and dry it using a towel. Do not rinse it with water.

Key Features

  • The molded finger and thumb grip makes this sharpener comfortable to use, whether you’re holding it with your left or right hand.
  • The lanyard hole gives you the option to wear this sharpener around your neck.

This product features ceramic sharpening rods (1,000 grit), a tungsten carbide, a serrated knife sharpener, and a diamond tapered rod (600 grit). It lets you restore the edge of a damaged blade with just three to four strokes.

One reason to choose this sharpener is its versatility. You can pick from four angles:

  • 20 Degrees for kitchen and pocket knives.
  • 25 Degrees for outdoor knives.
  • and 30 Degrees for heavy cutting tools.

With multiple angles, expect this product to sharpen any blade you have in your arsenal.

Similar to the Smith’s 50982 Pocket Pal Knife Sharpener, this tool is the best pocket knife sharpener to have in your pocket in the great outdoors. At 4 ounces, though, this one’s a bit heavier. Its frame is cast metal, which adds to its weight.

Key Features

  • The serrated knife sharpener is designed to get inside small serrations.
  • A small but strong magnet holds the diamond tapered file in place in either open or close position.
  • This sharpener is compact enough to fit inside your pocket or purse but still comfortable to grip with either hand.

5. Victorinox VN43323 Knife Sharpener

Victorinox 4.3323-X1

When you mention the name Victorinox, only one thing comes to mind: Swiss Army Knives. With this sharpener, it’s safe to say that you can expect the same level of quality you get from those famous multi-tool pocket knives.

This product can easily fit in your pocket or bag, making it an ideal sharpener for traveling. Packed in its pen-like form is a ceramic notch and a grinding stone, and both these features provide excellent results with straight-edge blades.

The V-shaped sharpener and aligner are designed well in a way that will keep you from damaging the blade’s mirror finish. Meanwhile, the long abrasive part is great for instances when you need to sharpen a very dull pocket knife.

While it’s not as good as the traditional whetstone, this pocket knife sharpener provides a handy way to sharpen and clean up a blade. The ceramic is also effective for cleaning up nicked edges.

Among all the items on this list, this is probably the best knife sharpener for beginners not only for its slim and compact form but also for being user-friendly.

Key Features

  • The ceramic V-groove and oval rod are placed in a lightweight plastic housing.
  • Its small size makes it ideal for sharpening fishing hooks.
  • The bottom end of the pen sharpener has a drainage hole to enable quick drying after cleaning and rinsing.

6. F Benchmade Guided Knife Sharpener

F Benchmade Guided Field Sharpener

When it comes to versatility, the F Benchmade Guided Field Sharpener won’t disappoint. Made in collaboration with Work Sharp, this product can hone scissor blades, pocket knives, serrated edges, and even fish hooks.

What makes this tool stand out is that it has coarse and fine diamond plates, plus dual ceramic rods and a leather strop. Since it has five unique components, there’s a bit of a learning curve when it comes to using this sharpener. Once you get the hang of it, though, you can use it to maintain the sharp edge of any blade.

Each component of this field sharpener has a 20-degree controlled angle guide. Even if you’re a novice, you’ll be able to hone your cutting tool without issues.

Despite the advantages, some users complain that the large Benchmade logo is damaged with repeated sharpening. There have also been complaints that the leather strop is also prone to falling off.

Key Features

  • The diamond honing stones are removable and replaceable.
  • The unit has a built-in lanyard slot that makes it easy to store or hang on a bag.
  • It has grooves on the handle that minimizes the risk of your fingers slipping while sharpening.

7. Work Sharp Guided Field Sharpener

Work Sharp Guided Field Sharpener

If you’re looking for a complete solution that can hone anything from pocket knives, scissors, fish hooks, broadheads, and edging tools, look no further. This guided field sharpener is the only product you’ll need.

In terms of design, this sharpening tool is quite similar to the F Benchmade Guided Field Sharpener, except this one comes in yellow and also does not have a logo etched on the diamond plates. With that said, you’ll have to sacrifice a bit of its aesthetic appeal if you choose this gadget over the Benchmade version, but the functionalities are essentially the same.

3 position ceramic rod

This sharpener includes fine (600-grit) and coarse (220-grit) diamond sharpening plates, two ceramic rods, and a leather strop. All elements are included in one handy package, so you can quickly finish sharpening with no need for additional tools or assembly.

Since most of the tool’s surface area should be used for sharpening, there’s only a small space for you to grip the product whenever you’re using it. If you’re honing a large blade, you may find it a little uncomfortable.

Key Features

  • It has a 25-degree angle guide for honing pocket knives with a strong micro-bevel, aside from the 20-degree one.
  • The product was engineered and assembled in the USA.
  • It comes with a limited lifetime warranty.

8. Sharpal 101N 6-In-1 Pocket Knife Sharpener

Sharpal 101N 6-In-1

When you’re out adventuring, every item you’re carrying should be worth the additional weight. So, if you’re looking for a lightweight product, then this Sharpal pocket knife sharpener should be your first choice!

This multifunctional survival tool comes with a coarse carbide slot, a fine ceramic plate, and a diamond rod for serrated knives and gut hooks. It also includes a Ferro rod, a high-pitched emergency whistle, and a fire starter. All pocket knife sharpeners are set at a 20-degree angle to give users consistent results.

This tool is best used to sharpen small blades, and it does that job very well! Most knife enthusiasts will be seriously impressed with the results they get from using this little gadget.

However, if you’re looking for something that can sharpen larger blades, this might not be the product for you. Also, since it’s quite a bit cheaper than competitor products, you can expect this sharpener to be slightly less durable.

Key Features

  • This portable sharpening tool measures 3.5 inches long and 1.2/5 inches wide. It also weighs only 1.5 ounces.
  • It comes with a soft rubber grip to help you keep it in place while you’re sharpening.
  • This EDC tactical knife sharpener comes with a 3-year warranty.

9. Lansky QuadSharp QSHARP Sharpener

serrated folding knife sharpener

If you need a basic pocket field sharpener that you can use for a straight-edge, curved, or serrated bread slicer knife, this is the product for you! It has premium carbide slots for extremely dull blades, plus an 800-grit ceramic bench stone for polishing.

Unlike other pocket knife sharpeners that are set at a fixed angle, this one gives you the option to choose among 17, 20, 25, and 30 degrees. However, with all this variety, you might have to do a little trial-and-error to see which setting works best for you.

Since this is a pull-through sharpener, it’s quite easy to use. Just hold your knife with your dominant hand, and the Lansky unit on the other, then pull the blade through your desired angle slot. Do three to four strokes, applying moderate pressure each time. Once you’re done, rinse your knife thoroughly.

The only issue with this inexpensive sharpener is that it can wiggle as you’re running the blade on it. If you’re inexperienced, you might accidentally end up dulling your pocket knife.

All things considered, this sharpener will hone a dull edge in a pinch. It’s easy to use, sturdy, and portable – so it’s a good tool to have when you’re out hunting or fishing.

Key Features

  • This product measures 8.63 inches in length and 3.5 inches in width.
  • This portable tool only weighs 3.5 ounces and can be hung on a keyring.

Ideal for honing anything from a santoku knife to a pocket cutting tool, this product has all the features you need in one small package. Its sharpening blades are also positioned at a fixed 20-degree angle to give you optimal results every time.

One of the main advantages of this sharpener is that it’s very easy to use. Just swipe the blade several times, and you’re done. With that said, you need to be a little bit careful, because this product can be rather abrasive and you might end up damaging your knife if you’re reckless.

The product has a patented suction cup that helps it stay in place on a countertop – this feature keeps your free hand away from the blade as you’re sharpening. If you’re out on the field, though, you might have a harder time looking for a flat surface where you can safely and conveniently use it.

Key Features

  • The product measures 2.36 x 2.56 x 2.36 inches and weighs 3.3 ounces.
