Both the S1 and S2 Advance Super Stones are 210mm long and 70mm wide (about 8-1/4" x 2-3/4").

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.
Two Stones | Three Stones | Four Stones | Five Stones | Six Stones | |

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 Advance Super Stones require flattening?
A. All water stones require flattening. The bonding material of the stone will wear, providing fresh abrasive material. This is why water stones sharpen so quickly. This is also why they need to be flattened periodically. We recommend the Naniwa Flattening Stone or a DMT Lapping Plate.
