Naniwa 135 Diamond Stone

Naniwa Diamond Stones in a Compact Size

These are the same as the Naniwa Diamond Water Stones but in a more compact size. Perfect if you want the fast cutting durability of Naniwa Diamond Water Stones, but don't need a full 8 1/4" long stone. More compact and priced lower than their larger cousins, the Naniwa 135 Diamond Stones are a practical option to consider for sharpening of smaller knives and tools.

Diamond Abrasive in Resin

These stones employ diamond abrasive bound in layer of resin mounted to a sturdy metal base. Rather than the single layer of diamonds found on many other diamond abrasive plates, the diamond abrasive layer on these stones is 1mm thick. This layer of diamond impregnated resin allows the stone to shed worn or loaded layers to expose a fresh cutting surface. This slow shedding of worn surface makes for a water stone sharpening experience with diamond abrasives that can handle the hardest sharpening situations.

Splash and Go

A light spray of water and Naniwa Diamond Stones are set to sharpen. Their feel when sharpening is similar to that of the hardest wearing water stones, neither unduly rough nor mushy or clay-like. As with all water stones, keep Naniwa Diamond Stones wet when sharpening and allow them to air dry in between uses.

Naniwa 135 Diamond Stones are 5 5/16" x 2 15/16" x 1/4" (135mm x 75mm x 6mm).

For Very Hard Steels and Ceramics

Naniwa Diamond Stones are particularly useful when you want a water stone style sharpener, but are working with extremely hard exotic steel or ceramic. Other stones may be very slow or even ineffective for ceramic or the hardest steel knives, chisels and plane blades, but because they are diamonds, if the abrasive in these stones won't sharpen the edge, nothing will.

Stones that Stay Flat Longer

The Naniwa Diamond Stones do not wear as quickly as other water stones. The resin binder that holds the abrasive material is very hard, making them slow to dish or cup, and long lasting. These stones are handy when performing tasks where flatness is of primary importance, as when flattening chisel backs or working the ride line on hair cutting shears.
