Even a good knife will lose some of its sharpness with time. However, sharpening a knife is easy if you have the right tool and know how to use it.
Sharpening steels with a chromium-plated, grooved surface deliver a fine re-sharpening result and are relatively immune to damages.
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.
