The pocket knife is the ultimate tool, ready to help you with just about any task. But it's only good to you if it's sharp enough to do the job.
Pocket knives are compact and portable, so you need a knife sharpener that also has those qualities. There's no point having a tiny pocket knife if you need to carry a huge sharpener to keep it usable. Pocket knife sharpeners keep things compact, so you can fit both items in your pocket, on your belt or in your bag.
I've reviewed some of the top pocket knife sharpeners to help you find the best pocket knife sharpener for your purposes. You can even sharpen full-sized knives with some of these options.

1. Victorinox Pocket Knife Sharpener - Best for Reliability from a Big Brand
[amalinkspro type="showcase" asin="B000AR7AKG" apilink="https://www.amazon.com/dp/B000AR7AKG?tag=wtw291-20&linkCode=osi&th=1&psc=1" new-window="true" addtocart="false" nofollow="true" sc-id="8" img-sizes="500:411,500:500,500:500,500:417,500:500,500:500,500:500" imgs="https://m.media-amazon.com/images/I/31x5qCTOs-L._SL500_.jpg~~~https://m.media-amazon.com/images/I/41ZM5Fiw6LS._SL500_.jpg~~~https://m.media-amazon.com/images/I/41HPBvz10bS._SL500_.jpg~~~https://m.media-amazon.com/images/I/31d1A3eAAgL._SL500_.jpg~~~https://m.media-amazon.com/images/I/311z21sw1jL._SL500_.jpg~~~https://m.media-amazon.com/images/I/51mO8f3KUdL._SL500_.jpg~~~https://m.media-amazon.com/images/I/41n9Dx0R0fL._SL500_.jpg" link-imgs="false" btn-color="#ff9900" btn-text="Buy on Amazon" alignment="aligncenter" hide-prime="0" hide-image="0" hide-price="0" hide-button="0" width="400" api="true"]Victorinox VN43323 Fixed Blade, Knife,Hunting,Camping,Outdoor, Black[/amalinkspro]
Victorinox is a huge name in pocket knives - in fact, it's one of the best known, if not the most famous. If you own a Victorinox pocket knife, maybe you'll want a matching sharpener to carry with it. This handy pen-shaped pocket knife sharpener is an excellent choice if you're looking for something compact, light and simple. Although it has fewer sharpening grades and functions than some other pocket knife sharpeners, it still have plenty to offer.
At 5" x 2" x 2" and weighing only 1.44 oz, it will easily fit into your pocket or any small bag. It has two sharpening functions, the rod and the ceramic groove. Unlike other sharpeners, the rod is ceramic and not diamond-coated steel. This makes it sturdy and durable, as it doesn't have a diamond coating that will eventually wear off. When you're not using it, you can enclose everything in the smooth case, which means no snags or tearing fabric. While there's no specific carrying mechanism, it's simply to carry without one.
The ceramic groove doesn't do such a good job as a sharpener. Of course, you don't have to use it, but many people prefer more than one sharpening grade. And as this sharpener only has two options, one of them not performing well isn't ideal.

2. Smith's PP1 Pocket Pal Multifunction Sharpener - Best Small and Lightweight Option
[amalinkspro type="showcase" asin="B000O8OTNC" apilink="https://www.amazon.com/dp/B000O8OTNC?tag=wtw291-20&linkCode=osi&th=1&psc=1" new-window="true" addtocart="false" nofollow="true" sc-id="8" img-sizes="500:500,500:284,500:500,500:500,500:500,500:500" imgs="https://m.media-amazon.com/images/I/41fQYkh9lIL._SL500_.jpg~~~https://m.media-amazon.com/images/I/31GZKMXR8GL._SL500_.jpg~~~https://m.media-amazon.com/images/I/61jw1mDOO3L._SL500_.jpg~~~https://m.media-amazon.com/images/I/41IkvrycItL._SL500_.jpg~~~https://m.media-amazon.com/images/I/41f2E4psqVL._SL500_.jpg~~~https://m.media-amazon.com/images/I/51Q8S8MVkIL._SL500_.jpg" link-imgs="false" btn-color="#ff9900" btn-text="Buy on Amazon" alignment="aligncenter" hide-prime="0" hide-image="0" hide-price="0" hide-button="0" width="400" api="true"]Smith's Abrasives PP1 hunting-knife-sharpeners[/amalinkspro]
If you're looking for a pocket knife sharpener that's as small and light as you can get, this Smith's sharpener is a great option. Measuring only 3.5" x 1" x 0.01" and weighing a featherlight 1 oz, it's one of the most compact and transportable choices you can get.
This pocket sharpener features three sharpening tools, including a diamond-coated tapered rod, carbide blades and ceramic stones. The tool has preset sharpening angles to give you the best results. The ceramic and carbide blades can be reversed and replaced, which helps the sharpener to last longer. The sharpener can be used to sharpen both flat blades and serrated edges.
However, this sharpener's small size can be a disadvantage too. Some might find it too fiddly and awkward to use. It's not the easiest sharpener to hold in your hand if you want something comfortable, and some will see that as a big disadvantage. If you prefer something more substantial, you might want to look for a larger option.
Still, this sharpener offers great results for a budget price. Its small size makes it easy to put in your pocket or clip to your belt or bag. The lanyard hole allows you to attach it to anything you want for convenience. It will easily sit alongside your pocket knife on a keyring or wherever else you want to keep it.

3. Lansky PS-MED01 BladeMedic - Great for Fast Results
[amalinkspro type="showcase" asin="B0085PPSIQ" apilink="https://www.amazon.com/dp/B0085PPSIQ?tag=wtw291-20&linkCode=osi&th=1&psc=1" new-window="true" addtocart="false" nofollow="true" sc-id="8" img-sizes="500:400,500:185,500:500" imgs="https://m.media-amazon.com/images/I/415TbtE2gSL._SL500_.jpg~~~https://m.media-amazon.com/images/I/41eQnDBDWoL._SL500_.jpg~~~https://m.media-amazon.com/images/I/41otV7dISFL._SL500_.jpg" link-imgs="false" btn-color="#ff9900" btn-text="Buy on Amazon" alignment="aligncenter" hide-prime="0" hide-image="0" hide-price="0" hide-button="0" width="400" api="true"]Lansky PS-MED01 BladeMedic[/amalinkspro]
If you're looking for a little bit more sharpening power, this Lansky option gives you four sharpening tools. It features carbide and ceramic blades, a diamond tapered rod and serrated ceramic knife sharpener too. This sharpener is designed to get you results quickly and to work on a variety of different blades.
This pocket knife sharpener should restore and finish your blade in three or four strokes each. The diamond tapered rod offers fast conditioning and maintenance to keep your blades shape and looking good. The serrated blade sharpener is designed for even the smallest serrated blades, which is handy if you want it to maintain your pocket knife.
One big problem with this pocket knife sharpener is that it's pretty heavy compared to some other options. It might not be weighing you down like a paperweight, but it's still a sizeable 4 oz. This is more than twice the weight of most of the other products in this review (except the other Lansky product).
It might not seem like a lot of weight but if you want to use the lanyard hole, clip it to your belt or even just carry it in your pocket, it's going to be more noticeable than the options that weigh well under 2 oz. Still, the lanyard hole is handy and makes it easier to carry.

4. Lansky QuadSharp Carbide/Ceramic Multi Angle Knife Sharpener - Excellent for a Choice of Sharpening Angles
[amalinkspro type="showcase" asin="B01BE8KCN6" apilink="https://www.amazon.com/dp/B01BE8KCN6?tag=wtw291-20&linkCode=osi&th=1&psc=1" new-window="true" addtocart="false" nofollow="true" sc-id="8" img-sizes="500:173,500:343,500:282,500:413,461:500" imgs="https://m.media-amazon.com/images/I/41JQj0SGlhL._SL500_.jpg~~~https://m.media-amazon.com/images/I/31u8WIz-BCL._SL500_.jpg~~~https://m.media-amazon.com/images/I/31BrR3gTOML._SL500_.jpg~~~https://m.media-amazon.com/images/I/31RR8nP+RSL._SL500_.jpg~~~https://m.media-amazon.com/images/I/61o2-2HskzL._SL500_.jpg" link-imgs="false" btn-color="#ff9900" btn-text="Buy on Amazon" alignment="aligncenter" hide-prime="0" hide-image="0" hide-price="0" hide-button="0" width="400" api="true"]Lansky QuadSharp QSHARP[/amalinkspro]
This Lansky sharpener, unlike others, offers a choice of different sharpening angles. For a novice knife owner, this might not mean much, and you're probably happy with preset angles. However, if you're a bit more knowledgeable, having the choice of four different angles gives you more flexibility to get your blades perfect.
The sharpener has angles at 17, 20, 25 and 30 degrees. The choice of angles allows you to choose the perfect option for any knife. Whether you want to keep your pocket knife sharp or you want a tool to tackle kitchen and utility knives, you can pick whichever angle works best. You also have the option of sharpening serrated blades with the ceramic benchstone, which is also excellent for finishing off your blades. The ceramic won't wear out, so it's a great addition to the sharpener.
One issue with this knife sharpener is that the parts are often a little loose. This isn't ideal for a knife sharpener, as you need everything to be stable to get good results.
Although this sharpener isn't as heavy as other options, it's still twice as heavy as the Victorinox at 2.88 oz. However, it's still a compact option and is smaller than the other Lansky model so it's slightly more comfortable to carry around.

5. Wusthof Black 2-Stage Pocket Knife Sharpener - Best For Lightweight Simplicity
[amalinkspro type="showcase" asin="B0002JENO8" apilink="https://www.amazon.com/dp/B0002JENO8?tag=wtw291-20&linkCode=osi&th=1&psc=1" new-window="true" addtocart="false" nofollow="true" sc-id="8" img-sizes="500:500,500:500,500:500" imgs="https://m.media-amazon.com/images/I/41m-bSPhAjL._SL500_.jpg~~~https://m.media-amazon.com/images/I/411+6Sut3TL._SL500_.jpg~~~https://m.media-amazon.com/images/I/41pX2kxo1AL._SL500_.jpg" link-imgs="false" btn-color="#ff9900" btn-text="Buy on Amazon" alignment="aligncenter" hide-prime="0" hide-image="0" hide-price="0" hide-button="0" width="400" api="true"]Wusthof 2-Stage Pocket Knife Sharpener[/amalinkspro]
The Wusthof 2-Stage Pocket Knife Sharpener is more simple than other products, but that makes it a good choice for anyone who doesn't want anything too complicated. The sharpening blades are labeled "coarse" and "fine" to make it straightforward and easy to use.
This sharpener measures a small 3" x 2" x 1" but it can handle both pocket knives and larger knives. The carbide slot for dull knives and the ceramic slot for polishing and finishing will help you tackle any knife. It has non-slip rubber inserts on the bottom for stability, so you can hold the sharpener in place on any surface and pull your blade through it. The textured grip makes it easy to hold while you're working.
The keychain on this sharpener makes it easy to attach to anything that you want. It's a great size and weight for putting on your keyring, your belt or your bag. It weighs only 1.6 oz, making it the second lightest option in these reviews.
For some people, this sharpener might be too simple. It doesn't offer many options, and many people prefer to have a sharpening rod, rather than carbide and ceramic blades within V-slots. It's also best for tackling slimmer blades, although it will sharpen knives of all sizes.

Buyer's Guide For The Best Pocket Knife Sharpener
What should you look for in a pocket knife sharpener? Whether you want something that you can carry around with you or keep in your kitchen drawer, you need to know what makes a good knife sharpener.
When it comes to pocket knife sharpeners, size and weight are obviously going to big factors to take into consideration. You want something that's easy to carry and that you can stash away in the smallest spaces. If you're looking for a small and portable item, you could be surprised by just how light you want it to be. Just a couple of ounces can make a big difference to the weight if you want to carry something in your pocket or clip it to your keys. You need to find a light product but balance the weight with solid construction. Some light products could be made of cheap plastic, which isn't ideal.
As for size, you want your knife sharpener to be no more than a few inches long. If you own a pocket knife, you probably don't want it to be a lot bigger than the knife itself, so you can use that for comparison. You might also want the option to attach your sharpener to something, such as a keyring or chain.
When you look at sharpening functions, you might have different preferences. Some people want to have a sharpening rod, which is often diamond coated. This is a flexible tool that you can use any way you want and on lots of different blades, but some people might feel a little less confident using it. Twin blades in carbide and ceramic can make it easier to sharpen knives, particularly for beginners or anyone who doesn't want anything too complicated. Ceramic benchstones are also useful, giving you the option of sharpening serrated blades.
If you're looking for a pocket knife sharpener, the five options above all provide great options for different types of users. Whether you're looking for a beginner tool that anyone can use or you want something a little more sophisticated, there's something for everyone. One of the best advantages of pocket knife sharpeners is that none of them are expensive. Even for a big brand like Victorinox, you don't have to spend a lot to get what you want.
Find the perfect pocket knife sharpener for you by reading the buyer's guide and working out what you're looking for. Decide what your budget is to help you choose a sharpener that falls within your range. You can make your choice based on price, size and weight, effectiveness, the number of sharpening options or just style. Choose a knife sharpener that you think will work for you and weigh the pros and cons carefully.
