MAC SR-85 Honing Rod

While steel rods are primarily designed to realign the edge of a blade, a ceramic rod like the MAC SR-85 offers a slight abrasive action. This means it not only realigns the edge but also polishes it, providing a finer, sharper finish than steel alone.

Yes, the 1200 grit ceramic surface is specifically designed to be gentle on harder Japanese steel. However, always use a light touch and maintain the correct angle to avoid chipping or damaging the delicate edge.

This is a honing rod, not a sharpening stone. It is intended to maintain your knife's edge between professional sharpenings by realigning the metal and removing microscopic burrs, rather than grinding away significant amounts of steel.

This rod is designed for straight-edge knives. Using it on serrated blades is not recommended as it will not effectively reach the serrations and may damage the rod's surface.

Those dark marks are simply metal particles from your knives. You can easily remove them using a standard abrasive kitchen sponge or a mild cleanser like Bar Keepers Friend to restore the rod's surface.

For most kitchen knives, you should hold the blade at an angle of approximately 15 to 20 degrees against the rod. Consistency is more important than precision, so focus on maintaining that same angle with every stroke.
