Video: How to Sharpen a Knife Anywhere

If you remember anything about knife sharpening, let it be this: A harder surface can sharpen a softer surface. Find a material harder than your knife, and it’s possible to hone an edge.

As this video points out, common materials can be used for knife sharpening in a pinch. Car windows, rocks, other knives and more are demonstrated. One not included, but cited often for alternative sharpeners, is the bottom of a ceramic coffee mug.

Learn more about the science behind sharpening in this knife maintenance download from BLADE, a sister publication.

And if you prefer more modern sharpening systems, Living Ready recommends this knife care kit from Sentry Solutions.

    There was some really good info in this video, thanks! BTW, what kind of knife was that?

    I have several compact knife sharpeners, and almost always have at least one of them on me:

    1) One of my favorites is my mini-diamond sharpener from SOG Knives. It has a small diamond stone, a ceramic rod & a ferro rod in one pocket sized tool. It makes a great addition to any survival kit!

    2) DMT 3-inch Dia-Sharp credit card sized diamond stones. I keep the fine & coarse stones in my wallet at all times. They make keeping a good edge on my knives fairly easy while I’m in the field & simply slide into the credit card section of my wallet.

    3) A Furi Diamond Fingers from Ozitech. I know, it looks like a useless gimmick; it’s not. If you’re careful with it you can touch up a dull blade fairly quickly & easily. It’s also really lightweight & folds up easily to fit into a pack.

    4) I also have one of those Gerber Bear Grylls carbide sharpeners, but it is only for use on machetes & the like. I don’t use it on my knives.

    5) Last, but not least, my Leatherman has a diamond file as one of its tools. :)
