Finding a 20 Degree Angle to Sharpen a Knife
A 20 degree angle is the most common angle to sharpen a knife. However, sometimes you just need a quick and easy way to find that angle. When nothing else is available, we've found that folding a piece of paper twice can serve as a good guide to finding the proper angle. When you fold a piece of paper twice, the resulting angle is 22.5 degrees. When sharpening by hand, a 22.5 degree angle is a good starting point. The idea is that you have a good starting point when you begin to sharpen.
