Japanese Waterstones: Naniwa

Japanese Waterstones: Naniwa Sharpening Stones / Super Stones

The Japanese waterstone maker NANIWA, based in Osaka, is known for making the best honing stones.

Naniwa sharpening and honing stones, in terms of hardness, lie between the Cerax and Chosera stones (more closer to the Cerax), and in use they have a very pleasant feel. One can almost sense the blade becoming sharper as one works.

The Naniwa Sharpening Stones / Super Stones in the finer grits are the best for honing. With no other stone can one achieve so fine an edge.

Waterstones do wear concave with use and require periodic re-flattening. Our flattening stones will do this job. A flat stone is indispensable for effective sharpening, especially with flat blades like chisels and plane irons.

Packing note: They are made for us without plastic stand. However on the packing is written: "with stand". Please ignore that.

Note on the Naniwa Name Change: The line Super Stone is now Sharpening Stone. Besides the name change, the packaging has changed as well to a size that fits the stones better. We will be phasing out the Super Stone over time and replacing them with Sharpening Stones. Both the old and new stones will be sold parallel as long as available. As the Sharpening Stones line is more expensive then its predecessor, purchasing the Super Stones while they are still in stock is the better choice.

NANIWA Combination Stone grain size 800/5000
Combination stone series for sharpening and honing
Now you can have the Naniwa stones’ quality in a combination stone. The only disadvantage to this, in common with all other combination stones, is that you have in every grit size only one surface to work with, and so one must resurface hollowed stones more often. Because of the slightly different working qualities of the Naniwa stones, the nominal grit size, 800/5000, of this stone is more comparable to the classic 1000/6000 sharpening-honing combination.
