Everyone needs a knife sharpener. It's easy to do and makes a major difference. Even the best of knives need to be sharpened, but even a cheap knife with a sharp edge is better than an expensive knife that's dull.
How to sharpen knives properly:
Place the knife blade against the tip of the sharpening steel at an angle of approximately 20 degrees.
Pull the knife down and across the steel, describing a slight arc.
Repeat this action on the back of the steel to sharpen the other side of the blade.4. Repeat steps 2 and 3 five to ten times, alternating the left and right side of the blade.
Note: It is very important to maintain the angle of 20 degrees and to run the full length of the cutting edge along the steel from the hilt to the tip of the knife. Speed of movement plays no part in this process.
