<p>The Naniwa Advance Super Stone is going through a name change that will affect packaging and labeling. The stones are still made of the same materials and the item numbers will remain the same. During this packaging and labeling change, you may receive a product labeled as a “Super Stone” or as “Advance”, however, these are the same stones. When you purchase more than one stone, we will do our best to provide you with stones that have matching labels and boxes.</p>

<h3>Naniwa S1 Advance Super Stone</h3>
<p>The Naniwa Advanced Super Stone gained fame as a hard-wearing, splash-and-go stone that created an unbeatable polished edge on steel. Sharpeners fell in love with them for being so user-friendly and such a good value.</p>
<h3>S1 Advance Super Stone is 10mm Thick</h3>
<p>The Naniwa Advance Super Stones come in two varieties, the S1 and the S2. They are exactly the same except for thickness. The S1 Advance Super Stones are 10mm thick. The <a href="/collections/naniwa/products/naniwa-s2-advance-super-stone"><strong>S2 Advance Super Stones</strong></a> are twice that at 20mm thick.</p>
<p>Both the S1 and S2 Advance Super Stones are 210mm long and 70mm wide (about 8-1/4" x 2-3/4").</p>
<h3>Resin Bonded</h3>
<p>Naniwa S1 Advance Super Stones are made with a resin bond. This resin bonding gives the Super Stones their unique attributes:</p>
<ul>
<li>
<strong>Splash and Go</strong><br>Resin bonded Advance Super Stones don't require soaking in water prior to use. Splash some water on the top of the stone, and it is ready to go.</li>
<li>
<strong>Less Flattening</strong><br>Resin bonded Advance Super Stones are harder wearing than many other water stones. S1 Super Stones won't dish or cup as quickly and will need less flattening less often.</li>
<li>
<strong>Higher Concentration of Abrasive</strong><br>Resin bonded Advance Super Stones have a high concentration of abrasive particles which contributes to speedy sharpening.</li>
</ul>
<h3>Available in 10 Grits</h3>
<p>Customize your sharpening tool kit with just the right combination of stones:</p>
<ul>
<li>
<b>220 Extra Coarse Grit - Tan</b><br>Recommended for establishing a new bevel angle or for extremely dull or damaged blades.</li>
<li>
<b>400 Coarse Grit - Green</b><br>A great coarse stone for edges that are not damaged or allowed to get extremely dull between sharpenings.</li>
<li>
<b>800 Medium Coarse Grit - Peach</b> - <strong><span class="redtext">NEW!</span></strong><br>A stone for when you need something a bit coarser than 1000, but don't want to remove too much.</li>
<li>
<b>1000 Medium Grit - Blue</b><br>An excellent follow up to a 220 or 400 stone or as a starting stone for not very dull edges. Very popular choice as a workhorse stone.</li>
<li>
<b>2000 Fine Grit - Yellow</b><br>Primarily used as an intermediate stone before finer grits, or as a finish grit for a toothy edge on knives.</li>
<li>
<b>3000 Extra Fine Grit - Red </b><br>A good final stone for a slightly toothy edge on knives or a nice progression between the 1000 and 8000 stones.</li>
<li>
<b>5000 Very Fine Grit - Light Blue</b><br>A popular final grit for knives that also works very well in progression between the 1000 and the 10,000 or 12,000 stones.</li>
<li>
<b>8000 Extremely Fine Grit - Light Yellow</b><br>A popular final stone for woodworking tools or for smooth cutting knives.</li>
<li>
<b>10,000 Extremely Fine Grit - Light Green</b><br>Slightly finer than the 8000, a wonderful final stage for very smooth cutting knives and tools.</li>
<li>
<b>12,000 Mirror Polish Grit - White</b><br>For a truly superb edge, a grit so fine your edge will shine like a mirror. Very popular with straight razor sharpeners.</li>
</ul>

<p class="Question">Q. Do I need to purchase every single grit?</p>
<p class="Answer">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.</p>

<p class="Question">Q. I've heard that these stones sharpen quickly. Does that mean I should skip the coarser stones?</p>
<p class="Answer">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.</p>
<p class="Question">Q. Do Naniwa Advance Super Stones require flattening?</p>
<p class="Answer">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 <a href="/collections/naniwa/products/naniwa-flattening-stone"><strong>Naniwa Flattening Stone</strong></a> or a <a href="/collections/dmt/products/dmt-dia-flat-95-lapping-plate"><strong>DMT Lapping Plate</strong></a>.</p>
