Why Do You Need The Best Field Knife Sharpener?

There are numerous reasons as to why these field knife sharpeners are essential. They are not just extra accessories or optional amenities. Every outdoor enthusiast, especially those who are wielding knives and other bladed tools, is required to bring these sharpeners. 

I have to emphasize as well that these field knife sharpeners may work better than sharpening stones. For instance, the units that I've listed here have ergonomics that enable users to utilize them properly. You may consider ordinary sharpening stones as your last option.

It Keeps Things Sharp

You don't want a dull knife.

In fact, that's one of the main reasons why you need to invest in knife sharpeners in the first place. After all, one cannot expect that these knives can remain useful when they are already dull. Knife sharpening has been a recommended practice to ensure the structural integrity and usability of bladed tools.

Outdoor applications will require you to cut a myriad of sturdy and rugged surfaces. These items can gradually decrease the edge of any blade. By honing the knife from time to time, you can guarantee that it will not succumb to the challenge. Knife sharpeners can essentially lengthen the lifespan of your blades.

It Maintains The Knife's Quality

Another important function of field sharpeners is maintenance. Regardless of how tough the steel of your knife is, it will eventually crack, especially if you use it frequently. Knife sharpeners are there to ensure that chips and cracks can be removed, ensuring that the knife will never lose its touch. 

If you have expensive or limited-edition blades, investing on these knife sharpeners is indeed a must.

It Is Useful For Other Bladed Tools

To sharpen a knife while on outdoors, you need these field knife sharpeners. But don't ever think that they are only suitable for knives. You have seen that most of the field sharpeners I listed in this post are capable of working with other sharp tools such as hooks, pins, and axes. When you have a field sharpener, you are automatically guaranteed that your other outdoor tools will get sharpened, too. 

How To Choose The Best Field Knife Sharpener

When selecting a field knife sharpener, attention to details is necessary. At this point, it is important that you are aware of the factors that make a particular sharpener exceptional and functional at the same time. By doing this, you will never to get a shabby and frustrating sharpening tool for your pocket knife and other bladed utilities.

  • Sharpening grits - When selecting a field knife sharpener, you need to ensure that it can do both coarse and fine sharpening. These two processes are important in ensuring that your knife will reach its maximum potential. 

Coarse grits are usually made from carbide stones. They are often used for extensive sharpening. Specifically, they are ideal for sharpening dull blades and repairing chipped and damaged steels.  These are great options for pocket knife sharpeners.

Fine grits, on the other hand, are usually tailored from fine ceramic stones. Their surface is not that rough, which makes them suitable for honing purposes. Keep in mind that honing and sharpening are not the same. When you hone a knife, it simply means that you are just maintaining its sharpness. 

  • Sharpening rod - Another critical feature of field knife sharpeners is a sharpening rod. Of course, I do recognize that not all sharpeners have them, especially if we are referring to whetstones. However, one should not downplay the importance of these rods in the overall maintenance of knives. 

Specifically, these rods are made from ceramic stones. They are used for sharpening the teeth of serrated blades. You cannot sharpen serrated knives through the conventional method; you need these rods to work on jagged edges one by one. Of course, these rods can work as a pocket knife sharpener.

  • Angle guides - Sharpening is a difficult task, especially for beginners. What you need to achieve here is not only sharpness; you also need to make sure that there's a consistency in the sharpness of the blade throughout its length. If you own various types of knives, such as kitchen knives, you would want a sharpener that can do different sharpening angles.

Normally, you cannot achieve such finesse with ordinary sharpeners. After all, it is difficult to control your strokes. But with the presence of angle guides, you will reach such precision in your work. You just pass the knife in the "guided" slot, and the blade gets sharpened according to its bevel. You can work with different sharpening angles as you have these guides.

  • Size - You also need to mind the size of the sharpener. Keep in mind that you are going to bring them into the field. Hence, it is pretty ironic if you are going to bring a bulky sharpener for these endeavors. For camping and backpacking purposes, the ideal pocket knife sharpener should be compact, lightweight, and easy to carry.
