- MAGNETIZED FOR SAFETY: While honing steels (sometimes referred to as sharpening steels) realign your knife’s edge for a sharper cut, they can also cause tiny metal particles from your blade to become airborne. Our honing rods are magnetized to prevent those particles from being inhaled or landing on nearby food.
- BUILT TO LAST THROUGH YEARS OF USE: Noble Home & Chef’s honing steels are made of high quality, hardened carbon steel. Every material in our honing rods was meticulously chosen. You won’t find cheap plastic handles or soft, inexpensive steel. When you hold it, the weight immediately reveals how solid the construction is, and the design adds class to any kitchen.
