Naniwa Diamond Series

The Naniwa Diamond Whetstones are a resin-bound diamond sharpening stone, specifically engineered for sharpening extra-hard high-carbide steels. Regular diamond plates only feature a single layer of diamonds bonded to a metal surface, which can wear down quickly and lose effectiveness over time. In contrast, the Naniwa Diamond stones feature a 1mm thick diamond-infused resin layer, allowing for a gradual shedding of abrasive diamond particles over several sharpening sessions. This design ensures consistent performance over extended use.

Additionally, the resin bonding gives this stone a sharpening feel similar to ceramic whetstones - firm yet responsive, without the harsh, overly aggressive feedback often associated with regular diamond plates. Whether working with Japanese knives or woodworking tools the Naniwa Diamond Stone provides an unparalleled sharpening experience, it's a stone with no downsides other than its price. If you are someone who sharpens extremely hard super steels on a regular basis, this stone could be the one for you.

Note: The aluminum backing of the Naniwa Diamond stones typically come with some scratches from the factory, this is normal and to be expected.
