Use the entire surface of the stone to maintain even wear.
Using Honing Rods and Steels
Honing with a rod or steel does not remove much material but realigns the blade's edge. Honing steel should be used regularly, even daily for professional chefs. Position the steel upright and sweep the knife down along its length, alternating sides. Consistency in the angle and pressure ensures the edge stays true without causing undue wear.
Finding the Right Angle and Pressure
Maintaining the correct 20-degree angle is crucial for most Western knives. Asian knives often require a finer 15-degree angle. Apply moderate pressure to the knife against the sharpening surface; too much pressure can damage the blade, while too little might not sharpen it effectively. Practice maintaining these parameters to sharpen efficiently and effectively.
Following Through with Honing
After sharpening, it's beneficial to follow up with honing to straighten any microscopic burrs on the blade's edge. Slide the knife's edge across the honing rod at the same angle used during sharpening, using a light touch. This will refine the edge and prepare it for immediate use. Regular honing minimizes the frequency of sharpening required.
Maintaining Your Knife’s Edge
To ensure peak performance and longevity of kitchen knives, one must prioritize proper maintenance, which entails regular honing, awareness of common misuses, and appropriate storage and handling techniques.
