You know the saying, “a sharp knife is a safe knife.” So here’s our guide to find the best pocket knife sharpener for you. Small enough for your pocket!
If you are out in wild, whether on a hike, a camping trip, or out hunting, nothing is more frustrating than a dull knife. All tools need some maintenance occasionally, and your knives are no different. Unlike most tools, the knife is an easy one to maintain in the field. Now, of course you can’t bring your typical knife sharpener with you from the kitchen, those are far too big. With pocket knife sharpeners, you have a handy little tool that fits right in your pocket but works just as well as the big kind.
A dull knife is not only annoying, it could be dangerous. You have heard the old saying, “a sharp knife is a safe knife.” That’s because a dull knife forces you to push harder when trying to cut something and increases the likelihood that the knife will slip. Not a good combination.
Best Pocket Knife Sharpener: What to Look For?
When forming this list of pocket knife sharpeners, we looked at a few basic metrics. First, the abrasive surface of the sharpener should have enough grit to work with just a few strokes of the knife.
Many knife sharpener’s also have useful safety precautions to protect your fingers from the knife edge. We prioritize sharpeners which have a good track record of safety.
You also want a sharpener that is not too oddly shaped or cumbersome to use. The sharpener should be small and easy to maneuver around knives of any style.
Pay attention to the geometry of the knife edge, because different knives required different angles of sharpening. The best pocket knife sharpener’s have adjustable angles to work with most any knife.
Furthermore, a good knife sharpener should feature multiple stages of grit, because different knives need a different treatment. This way, you don’t use the big guns, on a knife that just needs a little polishing.
Keep in mind that carbide sharpeners, which are present in many of these pocket tools, are aggressive and designed only for the dullest blades. Don’t sharpen with carbide if you don’t need it. The same is true of V notches, can shorten the lifespan of your knife if used improperly or excessively. When it comes to knife sharpening, less is often more.
If you have a serrated knife, know that the sharpening technique is different, and will involve using a rod-shaped sharpener, and running it along the knife edge between serrations, perpendicular. Thankfully, most of the options on this list feature such a rod in a handy, fold-out arrangement.
