Oilstones, like the Norton whetstone, can be made out of natural or synthetic material like Novaculite, Aluminium Oxide, or Silicon Carbide. As per the name, oilstones require the use of oil as you sharpen your knife's blade. This type of stone is slower at sharpening or honing a blade and it can be messy and you need to always have some oil on hand but it creates a nice sharp edge and a beautiful polish.
✅ SAFE & EASY TO USE: We understand the importance of safety when dealing with sharpening tools, your purchase comes with Silicone base for holding the stone inside Non Slip Bamboo base, this setup will ensure the stone is FIXED IN ONE PLACE while sharpening. Using our whetstone is extremely Easy & Economical. You don’t need any expensive sharpening/honing oil as its designed to work best with water. And it can be easily cleaned with water.
The diamond on top of the stone ensures that the surface is very hard. As such a diamond sharpening stone remains flat and will not become hollow like a water stone. For this reason diamond sharpening stones will last a very long time and help you to quickly sharpen your knives: a blunt blade will be razor-sharp in no time, even when you are sharpening hard types of steel.
Notice how I left out the shapton 1000 grit and 220 grit stones. Here is why: The DMT stones at those grits are cheaper, last longer, and stay flat forever. The shapton stones cut a little faster, but that doesn't make them entirely better. I've had my set of shapton glass stones for about 3 years now and sharpening almost every other day has led to the 1000 grit stone being worn down nearly to the glass on back side. All the other stones are fine for a few more years. There is no doubt that this stone wears down faster than all the others, even the 220 grit one. at 4000 grit and above, however, the shapton glass stones are a woodworker's dream; really the best there is. With that said, consider the short list of sharpening tools I have suggested above. With all 8 of those things you should be set for many years of high-quality wood working!
The basic concept of sharpening is simple – you're using an abrasive edge to remove metal – but the knife you buy may alter the method you should use. A general rule of thumb is that a waterstone can be used for both Japanese- and Western-style blades, but you should avoid pull-through sharpeners for Japanese knives (or any knife with very brittle blades).
LAST LONGER:- It Is Proven That If You Regularly Sharpen Your Knives They Will Stay Sharper For Longer Meaning You Won’t Need To Buy A New Knife Every Month. Our Dual Grit Sharpening Block Is Designed To Keep Your Blades Sharp And Maintained. Use The 1000 Grit In Order To Prem/smooth Out The Blade Where The 6000 Grit Is Used To Finish The Honing Of The Blade.
When the block is intended for installation on a bench it is called a bench stone. Small, portable stones (commonly made of bonded abrasive) are called pocket stones. Being smaller, they are more portable than bench stones but present difficulty in maintaining a consistent angle and pressure when drawing the stone along larger blades. However, they still can form a good edge. Frequently, fine grained pocket stones are used for honing, especially "in the field". Despite being a homophone with wet in most dialects of modern English, whetstones do not need to be lubricated with oil or water, although it is very common to do so. Lubrication aids the cutting action and carries swarf away.
The Juuma sharpening and honing stones offer a simplified working principle while at the same time ensuring the highest possible quality in the offered grits. Juuma Cobalt Blue stones are made of an aluminium oxide and a bonding agent. Adding cobalt serves to slow stone abrasion and increase the speed of sharpening. The speed bonus is especially marked when stoning blue steel (blue paper steel that is often used for Japanese planes and chisels). The cobalt gives the stones their blue colour. Juuma is our proprietary brand. Juuma sharpening stones are produced by a renowned Japanese whetstone manufacturer.
Natural stones are quarried from deposits of a mineral called novaculite. The most available are called Arkansas Stones, and come in soft and hard grades, but Washita (coarser than soft Arkansas) and Queer Creek Blue (variable, but around hard white Arkansas) are also available. Novaculite has a mohs hardness of 6.5, equivalent to Rockwell Rc 69. Most knife blades are around 5.5 (Rc 59).
I enjoy these stones so much that the feedback is not a deterrent at all for me, I don’t even think about it. The results are always nothing but top notch, they deliver exactly what I want, some of the sharpest knives I have ever produced were sharpened on Shapton Glass stones. They may be thinner but they last a very long time, they are easy to maintain as well,
Our large selection of stones will allow both professionals and those only starting their adventure with Japanese knives to find, from among the many famous manufacturers, the ideal stone for their need. Because every manufacturer formulates their stones to emphasise a different mix of qualities, and those qualities can vary widely between the different stones, for an optimal sharpening stone set, most woodworkers need stones from several different companies. There is no correct solution for any situation: the stones must fit one’s need and work style.
Medium Grit Stones: The number range here is from 1000 to 3000, with the latter being the basic, go-to sharpening stone. If your knives have lost their edge and need a good sharpen, then this is the grit you should start with. Don’t use it too often or the knife wears down rapidly. If you like to sharpen regularly, then the 2000 and 3000 grit are the ideal choice as they are less coarse, but please remember they are designed for sharpening and not maintaining the edge.

Historically, there are three broad grades of Japanese sharpening stones: the ara-to, or "rough stone", the naka-to or "middle/medium stone" and the shiage-to or "finishing stone". There is a fourth type of stone, the nagura, which is not used directly. Rather, it is used to form a cutting slurry on the shiage-to, which is often too hard to create the necessary slurry. Converting these names to absolute grit size is difficult as the classes are broad and natural stones have no inherent "grit number". As an indication, ara-to is probably (using a non-Japanese system of grading grit size) 500–1000 grit. The naka-to is probably 3000–5000 grit and the shiage-to is likely 7000–10000 grit. Current synthetic grit values range from extremely coarse, such as 120 grit, through extremely fine, such as 30,000 grit (less than half a micrometer abrasive particle size).[citation needed]
The newly designed dual-sided combination whetstone from Fallkniven features a super fine white ceramic stone (0, 1 micron) with a grit of 1400 to 2000 and the dark grey ceramic stone is made of synthetic sapphires (1 micron) and has a grit of 800-1000. There is no need to add any oil or water, just lay the blade on the stone, raise the blade's spine and deburr your blade on the grey side until it has a razor-sharp edge and then use the smooth white side to get a nice polished edge.
