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?

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.

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.

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.
