The 8 Best Pocket Knife Sharpeners

  • by

Pocket knives are pretty handy and important to carry in case you need to open something up urgently, cut out or hold onto an object when you’re outdoors.

Ensuring that your pocket knife continues to serve its purpose well and regularly maintaining it is equally important in this sense.

For this, a good pocket knife sharpener can go a long way to extend the lifespan and convenience of your pocket knife while also continuing to give it its edge.

There are loads of options available to you due to the growing market size, but there are a few ones that stand out. You can go through these and their fair reviews below, along with some other considerations that can help you decide on an option for yourself.

Kinds of Pocket Knife Sharpeners

With the varieties of pocket knife sharpeners available, being aware of them can help you determine which one will suit your needs best. Take a look!


Sharpening stones can be of varying thicknesses that can help you sharpen a pocket knife by pushing it against the stone. This can get rid of any excess metal and bring back the edge of the knife. These are usually conveniently sized, making them easy to carry in your kit.

Steel Rods

Steel rods are pocket knife sharpeners that can sharpen the knife and bring back its functionality. These can be of different lengths and thicknesses as well and work in a similar manner as stones, although you will need to take some time to figure out how exactly to use them.

Knife Hone

Coming in a range of shapes and sizes, a knife hone can rework the metal on the knife to sharpen the edge a bit. This is usually used towards the end of the process alongside some other tool, making it insufficient on its own to sharpen dull knives.

Electric Sharpener

Electric sharpeners can reduce the effort on your part since they make use of sharpening discs to sharpen your pocket knife properly. You will need to maintain safety levels while also keeping track of the process so that you do not get injured or overdo it to a considerable extent.

Straight vs Serrated Blade Sharpeners

Knives can be either straight or serrated, which usually has to do with how the blade looks. Straight knives have a straight or flat (but still sharp) blade while serrated knives have spiked blades.

Usually, you can use various kinds of sharpeners for straight blades but for serrated ones, the ideal choice might be to go with steel rods to ensure precision.

Factors to Account For

You will need to keep a few factors in mind while picking a pocket knife sharpener so that you know what to expect. These include the following.


Make sure you account for the dimensions or size of the pocket knife sharpener. Ideally, small ones can serve you well since you can both handle them safely while also carrying them around easily.

Make sure the weight is low enough as well so that you can make the process easier for yourself.


It can help to have an angle that is already set for you, especially if you are not used to working with pocket knife sharpeners. However, an adjustable angle can help you control the angle based on the kind of knife that you want to sharpen.

Make sure you go through any relevant instructions about this kind of adjustability as well.

Sharpening Stages

During the sharpening process, the initial stage will allow you to get rid of the metal and sharpen the knife while the later stage will provide a good finish. The grit should ideally be higher in the former and acute enough in the latter.

For sharpeners, it can help if you can get both.


Abrasives are usually added to sharpeners to make the process more efficient. It can help to have these abrasives on the sharpener, especially diamonds, aluminum, chromium or ceramic, among others. These, along with rods, can help ensure the durability of the knife.


Ideally, the sharpener that you opt for should be widely applicable and versatile so that you can use it to sharpen different kinds of sharp edges such as straight blades, serrated blades, scissors and other relevant tools.


Ensure that the sharpener you are working with is safe enough to use. This includes safety measures on your part and some precautions that the sharpener itself can provide, such as additional accessories (like gloves) and guards.
