Keep your knives sharp between professional sharpenings with this ceramic honing rod. It's 8 inches long (about 12.99 inches total with the handle) and made from high-hardness aluminum oxide ceramic. One side has grooves for realigning and minor sharpening, and the other side is smooth for finishing and polishing. The white ABS handle is lightweight and ergonomic, with a hanging hole for storage. To use it, hold the rod vertically (tip on a towel for safety). Hold your knife at about a 15-20 degree angle to the rod, and with light pressure, swipe the blade from heel to tip, down the length of the rod. Do this 5-10 times on each side. Important: This is for realigning the edge (honing), not for sharpening a completely dull blade. It works on all steel knives but NOT on ceramic knife blades. The rod is fixed securely into the handle to prevent wobbling. A must-have tool for any home cook or professional chef to maintain that razor-sharp edge. Keep your knives happy, and they'll make prep work so much easier.
