"Give me six hours to chop down a tree and I will spend the first four sharpening the axe." This quote is often wrongly attributed to Abraham Lincoln (spoiler alert: 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 — or if we're keeping with the metaphor here, wood.
A sharp blade is a source of satisfaction thanks to its practical applications (smoother, more efficacious, safer cutting) as well as to what it represents: taking pride in and caring for 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.
If you're the brand-new owner of a quality pocket knife or want to shore up the one you've carried in your pocket for the last couple of years, it's never a bad idea to think about how to maintain the quality of the blade you're relying on for everyday situations. If you haven't gotten a knife sharpener yet, here's where to start. (Seeking fundamentals? Scroll to the bottom for some FAQs.)

What kinds of pocket knife sharpeners are there?
Considering how many types of pocket knives exist, it follows that there are a few types of pocket knife sharpeners, as well. Pocket knife sharpeners range from manual options you can carry in your pocket for on-the-go maintenance, to secured, electric versions that stay put on your workbench — and many versions in between. For the purposes of simplicity, we're keeping our list to four main types: sharpening stones, sharpening steels, knife hones and electric sharpeners.
- Sharpening Stone: These simple tools sharpen knives by grinding the blade against an abrasive surface.
- Sharpening Steel: A rod of steel, ceramic or diamond-coated steel used to restore sharpness to dulled blade edges by removing metal via diamond (or other sharpening materials) embedded in its surface.
- Knife Hone: Knife hones don't remove any metal from your knife; rather, they reshape it and force the edge of the knife into a sharp point.
- Electric Sharpener: The most high-tech of the bunch, electric sharpeners do the work for you, using grinding wheels or belts to remove metal quickly. They're convenient and make short work of a chore, but if you're not careful, you can damage your knife.
- Whetstone: A whetstone is the most precise way to sharpen a knife; it's a rectangular block with a coarse side and a fine-grit side. Before you use a whetstone, make sure you know the correct sharpening angle for your knife.
What's better: manual or electric?
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. There is no right or wrong path here. Pick whichever fits your lifestyle, and accept its pros and cons.
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.
