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.
Generally three different materials are being used for sharpening steels:
Sharpening steels with a chromium-plated, grooved surface deliver a fine re-sharpening result and are relatively immune to damages.
Sharpening rods with a ceramics blade sharpen gentle and careful. However, the ceramics blade is sensitive to shock. A fall can easily damage it.
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.
