Why Japanese Water Stones Are So Popular?

A tried-and-true method for mending, honing, and polishing kitchen knives is the use of water stones. Whetstones come in a variety of forms, including natural and synthetic, water- and oil-based.  

Water Stones  

Before storing, every whetstone needs to be carefully cleaned, dried, and flattened after each sharpening session. The history of water stones, also known as whetstones or sharpening stones, is highly practical and dispersed. Stones were the first tool used to sharpen blades since they could be easily carved into any size and form.  

 Japanese water stones are softer than other whetstones, they may produce a sharp cutting edge rapidly. Like the majority of whetstones, real Japanese water stones are carved from sedimentary rocks. To make softer water stones, the rocks in the Japanese quarries had a special composition consisting of tiny silicate grains mixed in a clay-like substance.  

Japanese water stones must first be soaked in water due to their high porosity. The overall soaking period might range from 30 minutes to over 24 hours because each natural water stone is unique. Depending on how long it takes the stone to stop creating air bubbles, this varies.

By properly filling the holes with water, soaking produces a flat surface for the blade to be sharpened. It also makes cleanup much simpler and aids in preventing dirt from getting within the stone.  

Natural or artificial, and oil or water stones, are the two groups into which all whetstones fall.  

Natural stones are prized for their genuineness and inherent beauty. Given that they are natural, they may not always have the same consistency or level of grit throughout the stone.    

Additionally, they cost more than synthetic alternatives. The finest users of natural whetstones are those who have some prior sharpening skills because they are renowned to give knives a distinctive polish.

Synthetic whetstones are created using bonded abrasives. These are frequently put on a metal sheet with aluminum oxide, silicon carbide, or diamond covering. A uniform grit size provided by synthetic whetstones enables quicker, more efficient sharpening.  

They are better for the majority of knife sharpening needs, more user-friendly, and more inexpensive.   

Whetstones, whether they are natural or synthetic, often require a lubricant, such as water or oil. The fluid helps convey the metal shavings and debris (also known as swarf) for simple cleaning, plugs any holes in the material and makes the sharpening motion smoother. Typically, the type of stone determines whether to use oil or water. Additionally, once either one is in use, it cannot be switched.

After being poured into the stone’s core, mineral oil or water is applied to the stone’s surface. Some water stones require an extended duration of submersion. You may use other whetstones dry, such as diamond or ceramic sharpeners.  

Japanese Water Stones: How to Use  

Water Stones  

Water is necessary for Japanese water stones before they may be used to sharpen blades. When the stone stops bubbling, which usually happens after 5 to 10 minutes of total immersion in water, all air pockets have been properly expelled from the water stone.   

Other water stones merely require the surface to be wet and are “splash and go.” To keep the stone moist as you sharpen, have a pitcher of water close by.   

Water Stones  

Start with a coarser grit if your knife requires a lot of sharpening. Knives that are reasonably sharp and only require a light polish can move right up to a finer grit.  

Place the water stone with the specified grit size facing up on a non-slip surface. Depending on whatever way feels more comfortable, the stone may be positioned either vertically or horizontally.  

The spine should be raised to a modest angle, generally, 10-15 degrees for a Japanese-style blade and 20-30 degrees for a Western-style blade, while holding the grip of your knife.   

Water Stones  

Move the knife up and down the water stone as shown here, with one hand on the handle and the other on top of the blade. From the tip to the heel of the stone, carefully glide the blade down the stone using the fingers of your holding hand.  

Keeping the same angle, pressure, and pace is crucial while sharpening knives. Locking your hands and wrists is the ideal strategy for doing this. Instead, use your arms and shoulders to control the blade.  After about 10 passes flip the knife and repeat the same process on the other edge.
