The 10 Best Pocket-sized Knife Sharpeners

You’ll rarely find any prepper who goes forth without a knife. An essential part of an EDC (everyday carry) setup or packed ready for use in the gravest extreme inside your bag, knives are among the most elemental tools at our disposal.

You can use a knife for all kinds of tasks: building a fire, cooking and eating dinner, emergency extrication or even shelter creation. Knives are the original multi-tool. You can, of course, use knives for self-defense also, against a man or beast.

pocket-sized knife sharpener

Is a rare outing that a knife will not accompany you and see some use. But even simple chores like opening envelopes, cutting twine and slicing tape will inevitably dull a knife’s edge, reducing its cutting power, slowly, incrementally over time until you’re forced to saw away frantically with it for even a simple job.

Aside from being frustrating and inefficient, this is downright dangerous. Your granddaddy knew what he was talking about when he said you’re more likely to get cut by a dull knife than a sharp one.

If you have to work extra hard with your knife to cut something, you’re more likely to slip and cut yourself. That doesn’t have to happen if you keep your knife sharp. Keeping a knife sharp means you’ll need a knife sharpener.

Whether you’re out on some adventure or escaping from a disaster you’ll need a knife sharpener small enough to go with you. in this article, we’ll be looking at 10 of the very best pocket-sized knife sharpeners.

Sharpen Often!

Let’s all get honest here: Most of us sharpen our knives when we absolutely have to, or once a year, if that. Actually, most of us don’t even do it then. It may come as a surprise to some of you, but knife sharpening is not a biannual activity.

Knife sharpening is something you should do fairly regularly whether you’ve been using your knife heavily or not. Cutting, poking, prying and scraping will all dull a knife’s edge, and it won’t be quite as good when it comes time for the next task.

And don’t come at me with some claims about crazy super steel that perpetually holds an edge or anything like that. Even the finest modern steels, and there are some really great ones out there, all dull with use.

It’s for this reason you’ll see professional guides and other hard-use professionals who use their knives regularly and really depend on them pull their knives out and sharpen them often. a little touch up, a little honing of the edge and it is back in tip-top shape.

Taking a sharp edge to razor sharpness, or a pretty good edge back to just sharp is a whole lot easier than taking a dulled or mangled edge to even workable sharpness.

Yes, we’ve all gotten a little lazy in this technologically advanced age. You may rely on a friend at a local knife shop or outfitter to sharpen your knives and keep them in good shape. You might get your knife sharpened when you get your oil changed.

It doesn’t have to be that way. And it doesn’t have to be a big chore, either. Maintaining a tool should not be some huge ritual. The little things, done regularly, make the biggest difference in longevity.

A Sharp Knife Close at Hand

Many of you will already have a sharpening getup. Maybe you’ve got water and Arkansas stones on your bench. Maybe you have some contraption designed to hold the knife at a certain angle to sharpen it properly.

If you’ve gone all out, you may even use a motorized device like a belt sander or a specialized power knife sharpener. There’s just one problem with all of those, as good as they work: you don’t take them with you!

Most knife sharpeners of any description are large, bulky, and typically need to be set up on a bench or flat surface to really do a good job with them.

What most of us need instead, or as a supplement, is a light, handy tool that can sharpen our knives right out of our hands. No fuss, no muss and no extra setup. you know, considering that we carry pocket knives, why shouldn’t we have pocket sharpeners?

What a concept! That makes too much sense to me. imagine a sharpener so small, so handy they can ride in your shirt or pants pocket and you’ll hardly notice it’s there.

That way, when you have a spare moment and inclination you can pull out your knife and the sharpener and, with a few seconds’ work, keep your knife’s edge as sharp as it can be.

Aside from sheer convenience making it more likely for you to sharpen your knife often, thereby keeping your knife in prime condition, these compact sharpeners take up next to no space and weight in your pack.

As all preppers know, ounces make pounds and pounds make pain. Every gram of weight that you decide to shove in your BOB must be justified. These super-compact sharpeners will help you save room and weight for even more critical items.
