How To Choose The Best Survival Knife Sharpener

At this point, we will be exploring some of the fundamentals that are involved in the selection of knife sharpeners.

Gone are the days that we have to rely on sharpening stones for sharpening our knives. Right now, we have a myriad of utilities that can restore the sharpness of our blades. The best part of this is that you don't have to pour huge investments. 

With the right skills and tools, refining a survival knife is entirely doable. 

Types of Knife Sharpeners

Electric Sharpeners

Electric sharpeners are quite popular these days, thanks to their efficiency in making blades sharp. Most of these sharpeners have two to three steps of restoring the edge of knives. 

Specifically, the use of coarse grit so that dull blades will be sharpened. After that, a fine grit is utilized to hone the blade that has been sharpened already. 

Once opening, these electric sharpeners will rotate the sharpening stone, enabling it to sharpen any blade inserted to the slot. Because of this ergonomic operation, you can always get your survival knife on its top shape. The simplicity that these electric sharpeners provide is one of the reasons why many love it. 

However, keep in mind that you can't bring electric sharpeners on your trip for the simple reason that there are no power outlets there.

Handheld Sharpeners

Meanwhile, handheld sharpeners offer an ergonomic way of sharpening the blades of knives. They are quite similar to electric sharpeners, but it is notable that handheld sharpeners don't have too many slots as compared to their counterpart. But it is a kind of limitation that you can ignore. 

One exceptional advantage of having handheld sharpeners is portability. Specifically, you can bring them anywhere you want, which is something that you can't do with electric sharpeners. They are compact and can practically fit on backpacks. 

They are great for outdoor enthusiasts since there's no fuss in bringing them anywhere. If you are constantly on the road, then handheld sharpeners should be a perfect companion for your survival knives. 

There are several mechanisms as to how handheld sharpeners sharpen and hone the blades. Some designs will allow you to place the sharpener on a flat surface and draw the knife on its slot. Others will require you to place the knife with its spine against the table so that the sharpener can work the length of the blade.

Sharpening Stones

Of course, we shouldn't forget about these sharpening stones. One way or another, they are the "original" sharpeners, and we should pay homage to them. 

There are three known materials used on these sharpening stones: aluminum oxide, silicon carbide, and Novaculite. However, they have their unique nomenclatures, too. They are called India, Crystolon, and Arkansas, respectively. 

Arkansas originated from the earth. It formed naturally and deemed to be genuine stones. Meanwhile, Crystolon and India are both man-made. 

Arkansas stones have varying grit--from coarse to fine. India stones are usually used for fine honing and sharpening. Of course, Crystolon works best in coarse sharpening.

Serrated Knife Sharpener

Most of these serrated knives are difficult to sharpen, especially if you are using ordinary sharpeners. Some survival knives there are serrated, so you need a special sharpener for them. If you are going to use the standard sharpeners, there's a good chance that you'll damage the serrated blades. 

You should always check if the sharpener is designed for dealing with dull serrated blades before buying it. It is crucial that you won't miss this point.

Other Considerations In Buying The Best Survival Knife Sharpener

  • Grit - These knife sharpeners vary on grit. If you are going to use stones, then make sure that they are double-sided. For electric and manual sharpeners, the grit can be configured in their settings. 

Grit is usually measured by the amount of metal shredded throughout the sharpening process. Coarse grit (1000 grit) should only be utilized whenever you are dealing with a knife that has chips and nicks. A medium grit (1000 to 3000 girt) is for sharpening dull knives that have no physical damages. 

Meanwhile, fine grit (4000 to 8000 grit) works like honing steel. It is used in further refining the edge of the knife.

  • Size - The size of the sharpener is also a factor here. Given that you are going to use the survival knives in your outdoor journeys, then you should also mind the bulkiness and weight of the sharpener you are going to take with you. 

Of course, bigger doesn't mean better. It still boils down on the construction and performance of the sharpener. Hence, you shouldn't hesitate to get small sharpeners, especially if the application or trip requires it. 

  • Speed - Knife sharpeners can usually get the job done. However, some sharpeners work faster than others. 

If you value your time, then you'll probably get annoyed by a 10- to 15-minute sharpening process. Both electric and manual sharpeners can do things faster, so you might want to prioritize them over the others. 

  • Consistency - You want the knife sharpener to produce the same results all the time. You want your blade to be sharpened without the presence of nicks and scratches on them. 
  • Sharpener's surface - The harder the material is, the better the performance of the sharpener becomes. The hardest material for sharpening is diamond. After that, tungsten carbide and ceramic comes next. 

The abrasiveness of the sharpening surface is determined by its grit. The higher its number, the finer its abrasiveness.

  • Sharpening angle - It is also essential that you can get a sharpener that enables you to sharpen your knife with ease. This feature is somehow influenced by the angle adjustments that a sharpener can provide. Specifically, you should be able to adjust its angle from 15 degrees to 20 degrees.
