It's probably happened to you before: You drive out to the trailhead or campsite and realize you left your knife sharpener back at home. Well, if you have your car or truck with you, you also have one of the best knife sharpeners around.
Not the exterior... no, never take a blade to that. We're talking about the window. If you can roll it down halfway, the frosted glass edge at the top of your vehicle's window will work as an excellent knife sharpening surface.
Outdoorsman Robert Arrington, a.k.a. deermeatfordinner, has more in the video below.
Pretty nifty, eh? It takes some practice, but this knife sharpening trick can come in very handy, especially if you forget to bring your knife sharpener with you on a camping or hunting trip. Just remember to check your blade before you head into the bush.
This trick will work on just about any glass surface that has a frosted edge. Similar surfaces that come to mind include glass-plated scales, window shelves and coffee tables, though, your wife might have qualms with you sharpening your blades on the coffee table.
