Naniwa S1 Advance Super Stone

Naniwa S1 Advance Super Stone

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.

S1 Advance Super Stone is 10mm Thick

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 S2 Advance Super Stones are twice that at 20mm thick.

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

Resin Bonded

Naniwa S1 Advance Super Stones are made with a resin bond. This resin bonding gives the Super Stones their unique attributes:

• Splash and Go
  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.
• Less Flattening
  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.
• Higher Concentration of Abrasive
  Resin bonded Advance Super Stones have a high concentration of abrasive particles which contributes to speedy sharpening.

Available in 10 Grits

Customize your sharpening tool kit with just the right combination of stones:

• 220 Extra Coarse Grit - Tan
  Recommended for establishing a new bevel angle or for extremely dull or damaged blades.
• 400 Coarse Grit - Green
  A great coarse stone for edges that are not damaged or allowed to get extremely dull between sharpenings.

  A stone for when you need something a bit coarser than 1000, but don't want to remove too much.
• 1000 Medium Grit - Blue
  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.
• 2000 Fine Grit - Yellow
  Primarily used as an intermediate stone before finer grits, or as a finish grit for a toothy edge on knives.

  A good final stone for a slightly toothy edge on knives or a nice progression between the 1000 and 8000 stones.
• 5000 Very Fine Grit - Light Blue
  A popular final grit for knives that also works very well in progression between the 1000 and the 10,000 or 12,000 stones.

  A popular final stone for woodworking tools or for smooth cutting knives.
• 10,000 Extremely Fine Grit - Light Green

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 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.
