Explanation of the use of each tool
Sharpening Stone
Sharpening stones are the most traditional tool for sharpening blades. They vary in shape and size, with grit options ranging from coarse to fine. Rough grit stones are best for removing nicks and dull spots, while fine grit stones are best for honing and polishing the blade.
- To use a sharpening stone, you must first wet it with water and apply a few drops of oil to the surface. This will create a lubricant between the blade and the sharpening surface, reducing friction and preventing damage to the sword. Hold the knife at a 20-degree slope and hone the blade using back-and-forth strokes. Check the sharpness of the blade regularly and continue honing it until it is as sharp as you desire.
Honing Rod
A honing rod is another tool for sharpening blades. It is meant to be employed with a reciprocating motion, similar to that of a whetstone. The abrasive surface of the honing rod is much finer than that of a sharpening stone, making it ideal for honing and polishing the blade.
- To use a honing rod, hold it at a 20-degree angle and hold the blade against it. Move the edge back and forth along the length of the rod. Check the sharpness of the blade regularly and continue honing it until it is as sharp as you desire.
Oil
- Oil is used to lubricate the blade and the sharpening surface during the sharpening process. This reduces friction, prevents damage to the edge, and makes the sharpening process much smoother. Any oil can be used, but mineral oil is recommended.
Clean Cloth
- A clean cloth wipes away any residue or debris on the blade or the sharpening surface. This is important because debris can clog the abrasive surface and make it less effective.
Safety Glasses
- It is advised to wear safety glasses to safeguard your eyes from any flying particles that may occur during the sharpening procedure. This is especially important if you use a sharpening stone, as the trash can be sharp and fly in different directions.

Preparing the Blender
The first step in sharpening your ninja blender blade is to prepare the blender itself. This involves detaching the edge from the blender and cleaning it to remove any residue or debris that may have accumulated on the blade. This will help ensure the blade is clean and free of any obstacles that may affect the sharpening process.
Detaching the Blade from the Blender
The first step in preparing the blender is to detach the blade from the base. Before you start, make sure to unplug the blender and wait until it has cooled down if it has been in use. To detach the blade, follow these steps:
- Remove the blender jar from the base. This is typically done by turning the pot counterclockwise to release it from the ground.
- Once the jar is removed, locate the blade assembly. The circular metal piece at the bottom of the pot houses the blade.
- To detach the blade, hold the assembly in one hand and use the other to loosen the edge from the base. This can be done by turning the blade assembly counterclockwise until it releases from the ground.
- Once the blade assembly is detached, carefully remove the blade from the body. Take care not to cut yourself when handling the sword, as the edges are sharp.
Cleaning the Blade to Remove Any Residue or Debris
The next step in preparing the blender is to clean the blade to remove any residue or debris that may have accumulated. This will help ensure the blade is clean and free of any obstacles that may affect the sharpening process. To clean the edge, follow these steps:
- Rinse the blade under running water. This will remove any food particles or other debris that may have accumulated on edge.
- Soak the blade in warm, soapy water for about 10-15 minutes. This will help remove any grease or other buildup that may have accumulated on edge.
- After soaking the blade, rinse it thoroughly under running water to remove any soap residue.
- Dry the blade with a clean towel or paper towel. Make sure to dry the knife thoroughly to prevent any rust from forming on edge.
Sharpening the Blade
Sharpening the blade of your ninja blender is an essential step in maintaining its performance and longevity. Two main methods to sharpen a blender blade are a sharpening stone or a honing rod. Each method has its pros and cons, so it is essential to determine which way is best for you based on your personal preferences and skills.
Using a Sharpening Stone
A sharpening stone is a traditional method of sharpening blades, and it can be an effective way to hone your ninja blender blade. A sharpening stone is a piece of abrasive material used to grind and sharpen the blade. To sharpen the edge with a sharpening stone, you need to follow these steps:
Determining the Type of Sharpening Stone to Use
- There are several sharpening stones, including whetstones, oil stones, and water stones. Each type of stone has a different abrasiveness level and is used for other purposes. Whetstones are typically used for honing and sharpening, while oil stones are used for fine honing. Water stones are the most abrasive type of stone, and they are used for sharpening and maintaining the edge of a blade.
When selecting a sharpening stone, it is essential to consider the type of blade you are sharpening, as well as your skills and preferences. A more abrasive stone will sharpen the blade faster, but it may also remove more material from the edge, affecting its performance and longevity. A less abrasive stone will be gentler on the blade, but it will also take longer to sharpen it.
Wetting the Stone
- Once you have selected the correct type of sharpening stone, you must wet it before use. Whetstones and oil stones should be soaked in oil or water for several minutes before use. Water stones should be soaked in water for a few minutes before use.
Applying Oil to the Stone
- If you are using an oil stone, apply a few drops to the rock before use. This will help to lubricate the blade and prevent damage to the edge and gravel during the sharpening process.
Holding the Blade against the Stone
- Once the stone is ready, you must hold the blade against the rock. It is vital to have the blade at a consistent angle, typically between 20 and 25 degrees, to achieve a constant edge on the blade.
Sharpening the Blade by Moving it Back and Forth
- With the blade held against the stone, you need to sharpen it by moving it back and forth along the rock. Maintaining a consistent angle and pressure on the edge as you move it back and forth is essential. You should sharpen the blade on one side of the stone, then flip the blade over and sharpen the other side on the other side of the stone.
Checking the Sharpness of the Blade Regularly
- As you sharpen the blade, it is essential to check its sharpness regularly. You can do this by running your finger along the edge of the sword or using a sharpness tester. If the blade is not sharp enough, you can continue to sharpen it until it reaches the desired level of sharpness.
Using a Honing Rod
Sharpening your ninja blender blade using a honing rod is a simple process that can be done in a matter of minutes. Honing rods are made of different materials, including steel and ceramic, and they are designed to restore the blade’s edge by realigning the metal fibers. This section will cover the steps involved in using a honing rod to sharpen your ninja blender blade.
Selecting the Right Honing Rod
- The first step in sharpening your ninja blender blade using a honing rod is to select the right rod for the job. There are different types of honing rods, each with advantages and disadvantages. The most common materials used for honing rods are steel and ceramic. Steel honing rods are more abrasive and can quickly sharpen dull blades, but they are also more prone to damaging the sword if not used properly. Ceramic honing rods are gentler on the blade but are not as effective at restoring its edge.
When selecting a honing rod, consider the type of blade you have and your personal preferences if you are unsure of what kind of honing rod to choose, a ceramic rod is a good choice, as it is gentler on the blade and can be used more frequently without causing damage.
Holding the Honing Rod at a 20-Degree Angle
- Once you have selected a honing rod, it is time to sharpen your blade. Hold the honing rod at a 20-degree angle, with the rod’s tip facing down. This angle is essential, as it ensures that the honing rod is in contact with the entire length of the blade, allowing you to restore the edge evenly.
Holding the Blade Against the Honing Rod
- With the honing rod held at a 20-degree angle, hold the blade against the honing rod, with the blade facing down. The blade’s edge should be in contact with the rod, and the knife’s handle should be facing up.
Moving the Blade Back and Forth
- With the blade in place, start moving the edge back and forth along the length of the honing rod. Be sure to apply light pressure as you move the knife back and forth, which will help restore the blade’s edge. It is essential to keep the angle of the honing rod consistent throughout the process, as this will help to ensure an even sharpening of the blade.
Checking the Sharpness of the Blade Regularly
- As you sharpen the blade, it is essential to check the sharpness of the blade regularly. To do this, run your finger along the blade’s edge. If you feel any burrs or rough spots, continue honing the blade until the edge is smooth and sharp. It is important to remember that over-sharpening the blade can cause damage, so be sure to stop sharpening the knife as soon as the edge is solid and smooth.
