Know before you buy
A standard honing rod simply realigns the edge of your blade, while this diamond-coated rod actually removes a small amount of metal to sharpen it. It is designed for restoring dull edges rather than just maintaining them between uses.
No, this tool is specifically designed for straight-edge blades. Using it on serrated knives can damage the teeth of the blade and the abrasive surface of the rod.
Yes, the elliptical shape of the rod provides a larger surface area for contact, making it easier to maintain a consistent angle. Additionally, the wide gauntlet-style guard offers significant protection for your hand while you work.
This sharpener is not dishwasher safe. To clean it, simply wipe the rod with a damp cloth after each use to remove metal filings, and dry it thoroughly to prevent any potential buildup or corrosion.
While it is optimized for high-carbon stainless steel, including Global’s CROMOVA 18, it is generally effective on most standard kitchen knife alloys. It is not recommended for ceramic blades, which require specialized diamond-based equipment.
