Blunt and dull knives are a nuisance, and blade sharpening is not always an easy thing to do without the right tools. Some people use an old fashioned method of a grinding wheel, like tinkers used to do. However, now there are more modern methods of effective knife sharpening. Consider the following methods when you need to sharpen your blades.
If you can get hold of natural flint, you can use that to sharpen your knives. Back in the Stone Age when people made knives and cutting tools from flint, they used flint against itself to create a sharpened edge.
Natural stone is also a good surface for sharpening knives. Running the blade along the flat edge of a smooth stone can sharpen the blade to cut like a razor. Wetting the stone is also good as it prevents the knife blade from scratching and scarring during the process.
This may seem unlikely, but it does work. When caught without a “Steel,” many chefs will use the edge of a car window to sharpen their kitchen knives. Open the car window to about 4 inches and run the blade across the edge of the window. The slightly curved surface offers a diamond-style cut, and while it won’t make the knife razor-sharp, it will give it enough edge to slice through a piece of meat.
