The Best Pocket Knife Sharpeners to Give Your Blades a Cutting Edge

“Give me six hours to chop down a tree and I will spend the first four sharpening the axe.” No, Abraham Lincoln didn’t say that (its true origins lie with an anonymous woodsman) but the meaning is what matters: a sharp, precise edge, whether on an axe or your EDC pocket knife, is worth its weight in gold.

Why a Sharp Knife Is Important

A sharp blade is a source of satisfaction thanks to its practical applications — smoother, more efficacious, safer cutting. It also shows that you take pride in maintaining your possessions. In a world of instant gratification and built-in obsolescence, it feels damn good to preserve the things you love, rather than replace them the minute an edge dulls.

Whether you’re the brand-new owner of a quality pocket knife or want to shore up the one you’ve carried for years, it’s never a bad idea to invest the time and energy into keeping it sharp. It might just give you the edge you need.

This give users the ability to sharpen and refine their pocket knives with ease and simplicity.

It’s also good for beginners, as it comes with a blade guide to help you get the best edge possible. Meanwhile, the bamboo case gives it a refined aesthetic that will inspire you to leave it on display — and maybe even use it more frequently than you would a less attractive option that stays stuffed in a drawer.

Are manual or electric sharpeners better?

There are two schools of thought when approaching the task of sharpening a blade.

You can do it the manual way, which provides knife-to-the-grindstone satisfaction but requires more time and effort. Or you can take the electric path, which offers uniform sharpening in less time, but is more expensive and, if you don’t pay careful attention, can over-sharpen and damage your blade.

How many times should you pass a knife through a sharpener?

For a manual sharpener, a good rule of thumb is to pull the knife through the sharpener three to six times using even pressure across the entire blade. You may need to pass it through a few times more if it is especially dull or damaged.

If you’re using an electric sharpener, pull the knife slowly and steadily through the slot three to six times on each side of the blade. For both methods, finish the job with one or two pulls through the fine grit side of the sharpener.
