The Naniwa Specialty Sharpening Stone is an exciting new Japanese Waterstone from Naniwa. This is the same stone as the Naniwa Sharpening Stone, but half as thick for an economical price. Each stone measures 8 1/4" long, 2 3/4" wide and 3/8" thick. Even though it is thinner, the Naniwa Specialty Sharpening Stone is thick enough to provide many years of sharpening.
These stones sharpen very quickly. With many of the modern steel alloys used in knives and tools, speed of sharpening can be an important factor when considering a sharpening stone. These stones work well on tough tool steels such as A2 or D2 and very hard stainless alloys popular in Japanese and western cutlery.
Recommended for Quality
We have been very impressed with the quality of these stones. Whether you're purchasing the very coarse 220 grit or all the way up to the extremely fine 12,000 grit, we’ve found these stones to be very consistently graded. If you’ve considered purchasing a set of Japanese water stones, we certainly recommend the Naniwa Specialty Sharpening Stones.
Splash and Go Resin Bonding
If you want to get down to the real details of these stones, they are made with a resin bond. The resin bond gives these stones two real benefits. First, the resin bond allows for a higher level of abrasive particles compared with less expensive methods of stone bonding. The higher abrasive levels contribute to the speed of sharpening. Second, these resin bonded stones don't require soaking in water prior to use, just a sprinkle on the top is all that is needed.
Made in Japan.
Available in the following grits:
220 Extra Coarse Grit - This grit is excellent for establishing a new bevel angle on a tool or knife. We also recommend it for sharpening extremely dull or nicked blades. The 220 grit sharpens very quickly.
400 Coarse Grit - This stone is the coarsest stone you will need if you maintain your edges. If your knife or tool is not damaged or allowed to get too dull between sharpenings, this 400 grit would be the coarsest stone needed.
1000 Medium Grit - This stone is a very popular grit choice because it really starts to refine the edge. This stone is an excellent follow up after using the 220 or the 400 grit stone. If your edge isn't very worn, you don't need to start any coarser than this.
2000 Fine Grit - This stone is fine enough for many applications. In the kitchen, this stone will leave your knife with an edge better than most factory edges. At this grit size, this stone is considerably finer than any stones marked "fine" that you will find in stores.
3000 Extra Fine Grit - This is a good final stone, however many people will use it as a nice progression between the 1000 and 8000 grit stones.
5000 Very Fine Grit - This is yet another good choice as a final grit for many tools and knives. This stone works very well after you've used the 1000 grit, and is fine enough to be used prior to the 10,000 or 12,000 grit.
8000 Extremely Fine Grit - This stone is extremely fine. This is a wonderful final stage for most knives or tool edges. We recommend using this after the 2000 or finer grits stones.
10,000 Extremely Fine Grit - This stone is also extremely fine. It is slightly finer than the 8000. This is a wonderful final stage for most knives or tool edges. We recommend using this after the 3000 or finer grits.
12,000 Mirror Polish Grit - If you want a truly superb edge, this grit is so fine that your edge will shine like a mirror. After using this stone, the edge will not appear to have any grit marks at all.
Q. What's the difference between the Naniwa Specialty Sharpening Stones and the Naniwa Sharpening Stones?
A. The make up of the stones is the same. The difference is that the Naniwa Sharpening Stones are twice the thickness of the Naniwa Specialty Sharpening Stones.
Q. Do I need to purchase every single grit?
A. No, having every grit is not necessary for proper sharpening. We stock every grit so you can customize your purchase to your needs. We often suggest starting your decision at your finest grit and then skip grits until you get to your coarsest grit. You can do a good job with 3 stones, but 4 is the most common for a complete set. We have come up with a few examples that will fit most budgets and will work very well together.

Q. I've heard that these stones sharpen quickly. Does that mean I should skip the coarser stones?
A. It is a very common mistake to purchase the finer stones and not purchase the coarser stone (the wisdom being that you can just spend more time on the finer stone). A 220 stone will sharpen many times (more than 10 times) quicker than a finer stone. Given the lower price of the coarser stone we consider them a good investment. You will have a better sharpening experience if you have a coarse grit stone in your sharpening arsenal.
Q. Do Naniwa Stones require flattening?
A. Over time, all waterstones require flattening. The bonding material of the stone will wear, providing fresh abrasive material. This is why waterstones sharpen so quickly. This is also why they need to be flattened periodically. Naniwa Flattening Stone or a DMT Lapping Plate.
Q. How can I tell my stones apart? There are no markings on the top.
A. Naniwa no longer puts markings on the tops of these stones. Once you use the stones, the markings (which never had the grit number anyway) were rubbed away. The grits of each stone have been and still are located on the sides of each stone.
