How Do You Use A Japanese Sharpening Stone?

Japanese sharpening stones, also known as water stones, are hailed for their superior sharpening capabilities. These sharpening stones are made from natural materials such as quartz and silica, and they come in different grit sizes, each designed for specific purposes such as sharpening knives, chisels, and other cutting tools. Using a Japanese sharpening stone may seem intimidating at first, but with proper techniques, it can be an easy and efficient way to sharpen your tools.

In this article, we will discuss how to use a Japanese sharpening stone effectively, from preparing the stone to sharpening different types of blades. Whether you are a professional chef or a DIY enthusiast, understanding how to use a Japanese sharpening stone can improve the lifespan and performance of your tools, making them sharper and more durable for years to come.

Quick Summary
To use a Japanese sharpening stone, first, soak it in water for about 10 to 15 minutes. Then, place it on a non-slip surface or use a stone holder. Hold the blade at a consistent angle and start sharpening with a coarse-grit stone, slowly working your way to a finer-grit stone. Keep the stone wet by using a spray bottle to prevent the blade from overheating. Finish by honing with a leather strop or honing rod to polish the edge.

Understanding the Basics of Japanese Sharpening Stones

Japanese sharpening stones, also known as water stones, are an essential tool for anyone who needs a sharp edge on knives, scissors, and other tools. These stones are made of natural or synthetic materials and come in a variety of grits, which determine how coarse or fine the stone is. The coarser the grit, the more material it removes from the blade, and the finer the grit, the smoother and sharper the edge.

To use a Japanese sharpening stone, it is important to first understand the basics. The stone should be soaked in water before use to provide lubrication and prevent damage to the blade. During sharpening, it is necessary to maintain a consistent angle of the blade against the stone, typically between 10 and 30 degrees. The blade should be moved in a circular or back-and-forth motion across the stone, starting with the coarsest grit and progressing to finer grits until the desired level of sharpness is achieved. With some practice and patience, using a Japanese sharpening stone can be a simple and effective way to keep your tools sharp and in good condition.

Prep Work: Cleaning and Soaking Your Sharpening Stone

To ensure a smooth and effective sharpening process, it is essential to properly clean and soak your Japanese sharpening stone before using it. The first step is to rinse the stone thoroughly under running water to remove excess debris or particles left from the previous sharpening session.

Once cleaned, submerge the stone in water for at least 10-15 minutes. This soaking process allows the stone to absorb enough water, which ultimately aids in the sharpening process. The ideal time for soaking can vary between stones, so it’s always best to refer to the manufacturer’s instructions. Furthermore, make sure to add water as needed as you sharpen to keep the stone moist and lubricated. Proper prep work not only ensures a more efficient sharpening experience but also prolongs the life span of your sharpening stone.

Mastering the Right Angle and Technique for Sharpening

The right angle is crucial while sharpening on a Japanese sharpening stone. To achieve the desired angle, you need to hold the blade at a particular angle and move it in a direction that complements the grain structure of the stone. Before starting, determine the angle of your blade, usually between 15 to 30 degrees, and hold it steady against the stone. Next, lift the blade slightly and start moving it in a circular motion while maintaining the same angle.

Technique is just as essential as the right angle. You need to ensure that the blade entirely makes contact with the stone, and you do not raise or lower the angle during the sharpening process. Additionally, it’s vital to apply equal pressure and use a light touch while sharpening. Keep in mind to use the entire length of the stone and start with the coarse grit before moving to the finer grit. With practice, you will soon be able to master the right angle and technique for sharpening japanese knives on a sharpening stone.

Tackling Nicks and Chips in Your Blade

Tackling nicks and chips on your blade can be a daunting task but with the right technique and tools, it’s a skill you can easily master. Start by identifying the location and severity of the chip or nick. If it’s deeper than 1mm, you will need to repair the blade before you can sharpen it. You can use a diamond plate or sandpaper to do this.

Next, you will need to remove the burrs that resulted from repairing the chip or nick. This can be done using a coarse grit stone. Run the blade at a 45-degree angle across the stone, going back and forth until the burr is gone. As you progress, switch to finer grit stones until you have a clean, polished edge. Remember to maintain the angle of the blade throughout the process. With a bit of practice, you will be able to tackle even the most stubborn nicks and chips like a pro.

Choosing the Appropriate Sharpening Stone Grit for Your Blade

Choosing the appropriate sharpening stone grit for your blade is crucial to achieving the desired sharpness. Sharpening stones come in different grit levels, which determine the coarseness or fineness of the stone’s surface. Generally, lower grit levels, such as 1000 or 2000, are used for shaping and repairing damaged edges. Meanwhile, higher grit levels, such as 6000 or 8000, are used for honing and polishing the edge to achieve a razor-sharp finish.

Consider the type of blade you are sharpening and its intended use when selecting the appropriate sharpening stone grit. For example, a chef’s knife would require a higher grit level, whereas a hunting knife may need a lower grit level. Remember to start with a lower grit level if the blade is very dull or damaged and gradually progress to a higher grit level until you achieve the desired sharpness.

Honing and Finishing Your Blade for Optimal Sharpness

Honing and Finishing your blade is the step that ensures optimal sharpness when using a Japanese Sharpening Stone. Honing means aligning the blade’s edge to give it a straight edge, while finishing gives it an ultra-sharp point. Here, you’ll start with a finer grit stone to hone the edge and then move to an even finer grit stone to get that razor-sharp edge on your blade.

When honing and finishing the blade, you should use light pressure to stroke the blade across the stone, making sure that you maintain a consistent angle. Make sure to wipe the blade clean after each stroke to monitor your progress and ensure that the blade is not overheated or damaged. Proper honing and finishing will not only ensure that your blade is sharp but that it can retain its sharpness for an extended period, giving you more time to work before the next sharpening session.

Best Practices for Storing and Maintaining Your Japanese Sharpening Stone

To ensure that your Japanese sharpening stone stays in optimal condition for a long time, it is crucial to store it appropriately. Avoid storing it in damp or humid areas, where mold and mildew might grow, and instead, keep it in a dry place. Locate a secure spot to store your sharpening stone out of reach of children.

Regarding maintenance, you should regularly clean your stone after each use to remove any metal fragments or debris that may accumulate. To clean it, use a soft brush and warm soapy water. Additionally, you can use a flattening stone to maintain your sharpening stone’s flatness and avoid creating grooves or dips in the surface. These steps will keep your Japanese sharpening stone in excellent condition, so it performs at its best when you need it the most.


Using a Japanese sharpening stone can be tricky at first but with practice, you can achieve a razor-sharp edge on your knives and tools. It’s important to choose the right type of stone for your needs and to keep it properly maintained. Follow the steps carefully and take your time, as rushing can lead to mistakes and an uneven edge on your blade.

In summary, sharpening your own knives with a Japanese sharpening stone is a great skill to learn and can save you money on professional sharpening services. With a bit of patience and practice, you can achieve a perfectly sharpened blade that will make all your cutting tasks easier and more efficient. So, invest in a good quality sharpening stone and start sharpening your knives like a pro!
