Comparing Naniwa Stones


Naniwa Has a Wide Range of Stones to Fit Every Need

Naniwa has been manufacturing quality waterstones for over 60 years in Osaka, Japan. They have developed several different lines of stones in that time, each with its own unique characteristics. Each stone line has different qualities of hardness, wear rate, cutting speed, and other factors. Having several options allows sharpeners to find stones with characteristics that match their particular needs.

Of course, having many choices also means that deciding which is best for you can be a little daunting if you're not familiar with their stones. In this article, we will present the various Naniwa stones in a way that will hopefully make the decision easier. We will give a brief description of each stone type and note how they compare to the others in several categories. We hope that this will be useful as you pick out the best stones for your sharpening tool kit.
