Choosing the Best Survival Knife Sharpener: Buying Guide

Now that we have taken a good look at our top 5 picks, the next logical step is to know what makes this selection your best option as opposed to other products and designs.  

An excellent knife sharpener is not just a coveted instrument — it’s a critical tool for outdoor situations. There are a few qualities that any good survival knife sharpener should have to ensure that you’re suitably prepared for anything that comes up. 

Portability

Ease of carriage is a quality that cannot be overemphasized when buying a survival knife sharpener. Especially with outdoor activities like hiking and camping, you don’t want the extra weight or impractical shape of a knife sharpener to slow you down or make your luggage/gear awkward. 

Portability means that your sharpener should be small, lightweight, and, if possible, make carrying easy. An  example of one such feature is the built-in lanyard hole. A good specimen of that is the Smith’s Abrasives PP1 hunting-knife-sharpeners, also known as the “pocket pal,” with its sleek and lightweight plastic casing.

These elements allow you to carry your sharpener anywhere: in your pocket, in your EDC kit, or just conveniently attached to your belt or pocket edge without feeling its weight. However, keep in mind that while you want your sharpener to be easy to tote around, don’t compromise quality for size and ease of carrying.

Non-Electric Operation

When investing in a knife sharpener, particularly for outdoor use, you have to take into consideration that the chances of magically encountering an electrical outlet in the wild are pretty much non-existent. Of course, in modern times it’s quite possible to carry a portable power source on planned adventures.

Nonetheless, in real survival situations, most outdoor enthusiasts are not likely to go through the trouble of carrying around cumbersome equipment with their gear. That being the case, electric knife sharpeners would neither be practical nor functional. The best options are manual knife sharpeners, so all our reviewed products meet this requirement.

Versatility

This word is likely to come up a lot in any article or review about survival knife sharpeners, which just goes to show how important it is.

Any quality survival knife sharpener should be adaptable enough to accommodate the variety of survival knives and tools. For instance, a sharpener that has rods and blades that work well, with standard edges, and an assortment of serrated edges, will serve you better than one which only works with one type of blade edge.

One of the top options for this awesome feature is the Work Sharp WSGFS221 Guided Field Sharpener. The unique 5-stage sharpening design accommodates all types of knives with specific solutions for serrated knives, standard blades, as well as other tools like gut hooks and fish hooks.

Multifunctionality

Just as your knife itself is a multipurpose tool, your survival knife sharpener should be multifunctional, too. An excellent sharpener should serve for repair, sharpening, and polishing purposes. 

Investing in a multi-tool saves you the trouble of having to carry extra equipment. Take our top pick sharpener as an example: the Sharpal 101N 6-In-1 Pocket Knife Sharpener. This little guy has additional features that are functional for a survivalist, like the emergency whistle and the fire starter. What a convenient and compact tool! 

Durability & dependability

Any gear that you select to carry on your expedition into a survival situation should by necessity be dependable and rugged enough to withstand the unpredictability of weather and all the strain that comes with being active in the field. 

Finding a knife sharpener that is both durable and long lasting under harsh outdoor conditions is paramount, especially when you consider the abrasive mechanism that sharpeners are made of.

If the sharpener has multiple small parts that you have to constantly assemble, disassemble, and reassemble before it can be used, then it’s automatically a no-go. At that point, it becomes not only a safety hazard but also a burden on the trail. The last thing you need in a survival situation is to have to constantly hunt for parts of your sharpener before you can use it.

Safety

Last, but definitely not least important, is the safety of the sharpener. Sustaining cuts and injuries from a tool that’s supposed to help you with survival would not only be annoying but can get dangerous considering that you’re way more vulnerable to developing an infection in the wild.

Choosing a survival knife sharpener that guarantees your safety is critical. This is easily ensured by an ergonomic handle that gives you a firm grip on the sharpener, as in the case of the AccuSharp Knife & Tool Blaze Orange Sharpener. This device also possesses a full-length guard that protects your fingers.

Any and every effort to neutralize the intrinsic hazards of working with sharp or pointy objects while in a survival situation should therefore be prioritized.

Do You Even Need A Sharpener?

Now that you know the key qualities to look out for in a sharpener, as well as some of the best manual survival knife sharpener options on the market, I suppose the natural question is, do you really need a manual sharpener in your kit?

Our answer is a strong yes. Here’s why:

We can all agree that a dull knife is inherently more dangerous than a sharp one because of all the extra pressure that needs to be exerted to make it work properly. The possibility of the knife slipping and causing injury to yourself and possibly others certainly increases with a dull blade. That’s where a good, dependable, lightweight sharpener comes in.

As opposed to lugging a full- size sharpening stone around in the field, a survival knife sharpener brings your knife and other tools to serviceable condition with little to no effort of a few quick strokes in a matter of minutes.

These sharpeners usually have simple and easy to use designs that allow you to quickly sharpen a knife in awkward or less than ideal conditions without worrying about slicing yourself in the process, all while weighing next to nothing. 

Great sharpeners also possess guides that keep the same edge bevel angle  throughout the sharpening process, making it easy for even amateurs to use.

How’s that for practicality!

FAQs About Survival Knife Sharpeners

Which Is Better, Ceramic or Diamond?

As with all things, both ceramic and diamond have advantages and disadvantages. Ceramic stones are slightly less abrasive and are more valuable after sharpening as they let you grind the blade to a finer edge, but they may not work as well as diamond ones on tougher steel.

Diamond stones are structured in such a way that allows you to get rid of even serious damages and set a sharp edge. On the other hand, they tend to eventually develop spots where the diamond coating thins and doesn’t work as well as before.

So, it really depends on what you want to get out of the sharpener and what tool you intend to sharpen. Of course, you can achieve the best result only by using both of them.

How Frequently Should I Sharpen My Survival Knife?

How frequently you should sharpen your survival knife depends on how frequently you use it, the dullness of your blade, and your personal preference regarding sharpness. Some people prefer to sharpen their blades after every use, others every couple of months, and some even restrict sharpening to a few times a year.

What’s actually important is that you should maintain a reasonable balance. Don’t wait until your blade reaches a state of absolute dullness before you restore its ideal sharpness. Nevertheless, there’s no need to sharpen your blade too frequently as the coarseness of the abrasive blade can quickly wear it out if you do so.

In essence, if your knife still functions decently but requires quick touch ups, it’s  best to stick to regular but not over-zealous blade honing.

Final Points

In any survival situation, your gear can be all that stands between life and death. A survival knife is an essential part of any survival gear and like all tools, can only be  as good as its upkeep. Keeping your knives sharp and at the ready should be the  priority of any outdoor enthusiast. Therefore, owning an excellent compact knife sharpener to keep your knife in perfect condition is imperative.

Investing in one (or more) of the best survival knife sharpeners on the market can lengthen the lifespan of your knife while also reducing the chance of injury to yourself or to others.

Keep in mind that it’s best to avoid complicated sharpening systems and stick to the compact and easy-to-use types like those reviewed in this article. All the models are reasonably priced considering the use that you would get out of them. 

If you happen to be  someone who is just starting out, the AccuSharp Knife & Tool Blaze Orange Sharpener is perfect for you. Be safe and smart out there, and carry a survival blade sharpener while you’re on the go!
