How to Choose the Best Pocket Knife Sharpener

You need a quality pocket knife sharpener that will give you a return on your investment. Specifically, you want a lightweight, portable pocket knife sharpener that can last ten sessions or more, or roughly around a year.

Take a look at the video above for a short guide for choosing the best pocket knife sharpener.

To determine whether a pocket knife sharpener is right for you, you need to look at the following:

Kind of Task

Before you decide what is the best pocket knife sharpener for you, you need to ask yourself what kind of task are you going to be using your tool for?

Are you using your pocket knife sharpening to hone or sharpen something? Honing and sharpening are different concepts in the knifing world.

Honing is more similar to straightening. For example, you hone your knife when it becomes misshapen or dented after cutting through a can. Sharpening, on the other hand, refers to the process of making your knife keener so it can cut effectively again.

Honing and sharpening tools are distinct and you can’t use them interchangeably, so be sure to identify what you are going to be using your pocket knife sharpener for before you decide to buy one.

Kind of Tool

You also need to ask what type of pocket knife sharpener you want:

  1. Whetstones or sharpening stones: The most popular and affordable, whetstones are rectangular stones that use water or oil to activate the sharpening surface. To use this type of sharpening, hold your pocket knife at the right angle as you run it down the whetstone. Typically made of aluminum oxide, silicon carbide, or Novaculite, they are an inch thick and can quickly wear down, so you would need to get a replacement as soon as it’s worn to the base.
  2. Sharpening steels and knife hones: These are long rods that straighten rather than sharpen. Accordingly, you should get these if you’re looking for realignment more than sharpening. Sharpening steels and knife hones can be further broken down into diamond steels, ceramic steels, regular steels (made of steel), or combination steels, which combine a smooth surface or honing and a rougher one for minor sharpening.
  3. Electrical sharpeners: Unlike whetstones, these need batteries or electricity to work. They also use a V-shaped notch or a rotating wheel to carve into your knife. While they are very quick and efficient, Unless you plan to use these sharpeners in a more urban area, it may be hard to get a lot of sharpening done using electrical sharpeners while out in the open. They may also be too bulky for your portable pocket knife.
  4. Handheld sharpeners: Like electric sharpeners, these can make the sharpening process much easier. They tend to be more portable than electrical sharpeners, making them a better fit for those of you who need pocket knife sharpeners while camping in a rural area.

Usage Requirements

You need to also take a look at what you need in order to use your pocket knife sharpener.

If you have a whetstone or sharpening stone, it may need moisture in order to work. In contrast, honing oil may work better for other sharpening stones. There are also knife sharpeners that will rust if they get wet, so you can only use them for dry sharpening, such as diamond sharpeners.

For electrical sharpeners, you will need rechargeable batteries or access to a power outlet. If you’re planning to take your pocket knife to a rural area where these may not be readily accessible, consider buying a handheld, whetstone, or sharpening steel.

Construction Materials

Since you are going to be taking your sharpener with you everywhere, you should look for one that is portable, lightweight, and compact.

At the same time, you need to weigh these considerations against the longevity of your tool. For instance, while plastic knife sharpeners are light and compact, they don’t last as long as metal knife sharpeners.


All knife sharpeners have different levels of grit. Whetstones are usually double-sided, while manual and electrical sharpeners tend to have a minimum of two settings.

If your pocket knife has nicks and chips, you should look for a sharpener with coarse grit.

Medium grit (300-400) is for dull, undamaged knives.

Finally, you should look for a sharpener with fine-grit (1200) if you need to refine your knife’s edge.


Finally, you need to consider whether your knife sharpener is flexible. How many kinds of knives can your tool sharpen? For example, electric sharpeners have presets for different types of knives. Some sharpeners also come with adjustable angling as well as serrated edges and curved cutting surfaces.

Now that you have a better understanding of what to look for when searching for the best pocket knife sharpening in 2021, let’s take a look at my list of the five best pocket knife sharpeners in 2021.

The Five Best Pocket Knife Sharpeners in 2021

Without further ado, here is a list of my top picks for pocket knife sharpeners this year, and what they’re each best suited for.

EDC Micro Sharpener & Knife Tool

The EDC Micro Sharpener & Knife Tool offers you an efficient and streamlined knife sharpening experience. Great for camping and hunting, this manual sharpener does not require batteries.


  • Angle guides that makes sharpening quick and efficient – great for beginners
  • Diamond (600 grit) and ceramic (equivalent to 3000 grit) sharpening that quickly hones and sharpens your knife
  • Small (6.1 x 5.2 x 0.5 inches), lightweight (0.14 pounds), and portable – you can take this anywhere
  • Great price
  • Lifetime warranty


  • Star/torque bits could be better
  • Angle guides can be confusing
  • Sharpening rods could be longer
  • Small size means you may have to take more time to sharpen large knives

All in all, the EDC Micro Sharpener & Knife Tool is one of the best pocket knife sharpeners in 2021. Not only is it great for beginners, but it can handle a variety of knives, from Swiss Army Knives to budget blade steels such as 8Cr13MoV.

However, due to its small size, it will take you longer to sharpen large pocket knives. The star and torque bits are a bit soft, but you can swap them out for stronger and more reliable bits.

Accordingly, the EDC Micro Sharpener & Knife is my pick for Best Overall pocket knife sharpener in 2021.

Smith’s Abrasive PP1 Hunting Knife Sharpeners

Built to last, the Smith’s Abrasives PP1 Hunting Knife Sharpeners is great for repairing knives that have dulled over time.


  • Lightweight and small (0.02 pounds, 3.5 x 1 x 0.01 inches)
  • Two grit types: fine, coarse
  • Lanyard hole for carrying
  • Carbide blades (coase carbide slot) and ceramic stones (fine ceramic slot) provide for efficient sharpening
  • Carbide and ceramic stones are reversible and replaceable
  • Preset sharpening angles for guaranteed results
  • Good price


  • Quality control could be better – coarse side can come chipped or arrive rusty
  • Does not sharpen as efficiently as advertised

Although this tool is not as hardy as my other picks, it is a good knife sharpener for its budget price. However, while it will make your knives workable, it is not as efficient as advertised and also will not make your knives extremely sharp.

The Smith’s Abrasives PP1 Hunting Knife Sharpeners is not perfect, but it is a decent pocket knife sharpener for the price. As such, it is my pick for Best for the Price.

Sharpal 101N 6-in-1 Pocket Knife Sharpener

Our pick for Best Accessories, the Sharpal 101N 6-in-1 Pocket Knife Sharpener is a force to be reckoned with.

Portable, durable, and versatile, it has everything you need to sharpen your knife.

In general, the Sharpal 101N 6-in-1 Pocket Knife Sharpener is a worthy investment. It comes with everything you need for your outdoor adventures and can sharpen a variety of knives. It can also hone your dull knives and help you start campfires. You can see why it is my Best Accessories pick.

Lansky PS-MED01 BladeMedic

The Lansky PS-MED01 BladeMedic is my best pick for beginners. Simple yet effective, it is easy to learn how to use and works with a variety of pocket knives.


  • Easy to learn how to use
  • Works with standard, serrated, fillet, and gut hook knives
  • Carbide, ceramic, and diamond sharpeners
  • Lightweight (0.23 pounds, 8.5 x 3.5 x 0.13 inches)


  • Rattles a lot while using
  • Screws can stick out a bit in the back
  • Carbide sharpeners could be more aggressive

However, this may not be the best pick if you are looking for a sturdy pocket knife sharpening with lots of functions. It rattles and the carbide sharpeners are duller than advertised, so it does not provide the most streamlined sharpening experience.

Work Sharp WSGPS-W

Finally, let’s take a look at the Work Sharp WSGPS-W. This powerful, lightweight tool is an effective sharpener and honer.


  • Aggressive sharpener
  • Great honer
  • Portable and light (0.1 pounds, 0.5 x 1.75 x 6.5 inches)
  • Budget price
  • Great for backpackers


  • Can be difficult to use, particularly for beginners
  • Diamond sharpener may be too aggressive for some pocket knives – can remove a lot of metal if you’re not careful
  • Too long to fit inside your pocket
  • Better at honing than sharpening

If you’re looking for a tool that can hone your dull pocket knives, the Work Sharp WSGPS-W is a great choice. However, I do not recommend it for beginners, since the diamond sharpener can easily ruin your pocket knives if you’re not careful or experienced enough.


After reviewing all five items, my Best Pick is the EDC Micro Sharpener & Knife Tool. Cross-functional, lightweight, and small enough to fit in the palm of your hand, this handy pocket knife sharpener makes for a great outdoors companion.

Unlike the Lansky PS-MED01 BladeMedic, the EDC Micro balances ease of use with portability and quality. In contrast to the difficult-to-use Work Sharp WSGPS-W, the EDC Micro is flexible and safe for beginners and pros alike. Accordingly, it is one of the best pocket knife sharpeners this year.

We hope that my buying guide and reviews have helped you narrow down the best pocket knife sharpener for you.
