The Different Kinds of Pocket Knife Sharpeners

Not all pocket knife sharpeners are created equal, and there are quite a few options available to choose from.

The first kind of pocket knife sharpener is a whetstone. Whetstones are manufactured from quarried material and are often a combination of diamond dust, rock, and concrete. Curved whetstones are a good pick for sharpening complex blades, while flat whetstones are most compatible with flat blades.

Whetstone sharpeners are very sturdy and reliable, but these take a while to learn how to use properly. So, if you’re brand new to using the best pocket knife sharpeners, you might prefer a more straightforward choice.

Slot sharpeners are frequently used for pocket knives because they feature a very simple design sporting slots to draw and sharpen your blade with continuous strokes. Slot sharpeners also feature a variety of angles, so if you’re brand new to pocket knife sharpeners these are a great choice.

These types of sharpeners are also compatible with a range of blades, including serrated, curved, and straight.

Multifunctional sharpeners have some fun bells and whistles added on, so if you want a few additional features when picking out the best pocket knife sharpener you might prefer this variety.

Multifunctional sharpeners come with handy features like a compass, light, and so forth, so you can even use them as a backup survival kit besides the regular pocket knife sharpener functionality.

Things to Consider When Selecting the Best Pocket Knife Sharpener

Here’s what you need to consider in order to pick the best pocket knife sharpener.


The first thing you’ll want to consider when picking out the best pocket knife sharpener for your outdoor needs is the activities you intend to use it for. Are you going to be skinning game or cutting ropes with your pocket knife? Or do you simply use your blade for things like cutting food or a backup tool when setting up camp?

Your knife will wear out way quicker if you use it for wilderness and survivalist adventures rather than if you use it for more everyday outdoor use. If you use different pocket knives for a variety of outdoor needs, you’re going to want the best pocket knife sharpener that is compatible with a wide range of blades.

If you just use a regular pocket knife out on the trail, you’ll need to pick a pocket knife sharpener that works for that particular type of blade.

Comfort Is Key

Your comfort as the user is a key component to take into account when purchasing the best pocket knife sharpener. Your sharpener shouldn’t be overly bulky or take up too much space in your gear. In fact, you should be able to fit the best pocket knife sharpener in your pocket with total ease.

The best pocket knife sharpener is designed for comfort, so you don’t have to worry about it poking out and hurting your leg if you store it in your pocket. Another handy feature that ensures comfort for the user is a hook or lanyard secured to the pocket knife sharpener.

That way, you can simply affix the hook or lanyard to your belt when you’re out on the trail.

Assess the Sharpening Angle

You need to be aware of the sharpening angle of the best pocket knife sharpener when hunting for the device that is ideal for your blade. The angle at which you sharpen your pocket knife translates to the fineness of the blade.

For example, if your sharpener is compatible with a 35-degree sharpening angle, you will have a fine edge, but not as durable an edge as a device with a 25-degree sharpening angle. If you are brand new to using the best pocket knife sharpener, just know that it may take a few tries before you get it right and feel comfortable using the device.

The best pocket knife sharpeners sport adjustable angles, which makes it much simpler for you to determine the angle that you're most comfortable with. Plus, if you’re new to pocket knife sharpeners, an adjustable angle will help ensure that you don’t harm the edge of your blade as you find your preferred angle.

Does the Sharpener Feature Sharpening Stages?

The best pocket knife sharpener sports different sharpening stages or grits, which is really handy to sharpen blades with varying levels of dullness. For example, a coarse grit allows you to sharpen the edge of a blade that has become really dull, while a medium grit is great for just slightly dull blades.

A fine grit is what you use when your blade just needs a mild sharpening to smooth out the edges. You want to pick a knife sharpener with varying grits, so you don’t have to purchase different sharpeners for different blades.

Does the Sharpener Include Safety Features?

Because you’re dealing with sharp blades, you need to make sure that the best pocket knife sharpener you select comes equipped with safety features to protect your fingers. The sharpener should include some type of protection to come between your ringers and the sharpener, so it doesn’t rub at or damage your skin when you’re sprucing up your blade.
