Keeping your blade honed to a razor edge is important. A sharp knife is safer to use and requires less energy. In survival, every calorie counts. You may not know that 2 excellent sharpeners exist almost right under your nose. First is the bottom of a ceramic coffee mug. The bottom ring of most ceramic mugs is almost always unglazed, and unglazed ceramic is a perfect knife-sharpening surface. The underside of toilet tank covers are also unglazed. Then there is the abrasive upper edge of a car window. This edge is sufficient for sharpening mostabrasive upper edge of a car window. This edge is sufficient for sharpening most carbon-steel blades. Slide the blade from hilt to tip along the upper edge just as you would use a sharpening rod.

unglazed = not covered with shiny coating

under your nose = easy to reach

abrasive = having a rough surface that will rub off a thin layer of another surface

carbon steel = a steel with carbon (C) content from about 0.05 up to 2.1 percent by weight

hilt = the handle of  knife
