The Naniwa Japanese Combination Waterstone is an excellent value in waterstones. These stones are available in the 120/1000 (extra coarse/fine) and the 1000/3000 (fine/very fine).
Like traditional waterstones, we recommend soaking these in water prior to use.
Each stone measures 175 MM long x 55 MM wide and 16 MM thick. In inches the stone measures 6 7/8" long, 2 1/8 wide and 5/8" thick. This size offers a good balance of value and size. The stones are bonded to the base. The base provides plenty of knuckle clearance when sharpening knives and is solidly built for sharpening tools.
120 - This stone has an extra coarse. This stone sharpens very quickly. Gray in color.
1000 - This stone is fine. If you are patient, this can sharpen even a very dull knife. However, where this stone really shines is in maintaining your knives and tools. The 1000 grit quickly refines a moderately dull edge. Red in color.
3000 - This stone is very fine. The 3000 grit side will hone an edge to a very fine level of sharpness. Tan in color.
Made in Japan.
Q. Do I need to soak all of the stones in water before use?
A. Yes, all of the stones will benefit from soaking in water prior to use. The 120 and 1000 will need more water while the 3000 doesn't require much soaking before hand. We do not recommend that you store them long term in water, only soak them before use.
