“Angle” is important in how to sharpen a knife

There are two important angles when sharpening a knife. Basically, let’s remember “15 degrees” and “45 degrees”. 15 degrees is the angle at which the knife placed on the grindstone is laid down. 45 degrees is the angle with respect to the grindstone when the knife placed on the grindstone is viewed from above. The point is to keep the angle and sharpen without hanging!

 

What you need to sharpen a knife / knife

  • Kitchen knife
  • Whetstone
  • Cloth (to prevent the grindstone from slipping. Prepare unnecessary items as it gets dirty)
  • A container sized to hold a grindstone (bathtub, bucket, etc.)

 

Before using the whetstone, soak it in a bathtub or bucket filled with water for about 30 minutes to absorb enough water and make it slippery. Use a grindstone that has absorbed moisture on a flat surface. You can prevent the grindstone from slipping by laying a wet and tightly wrung cloth under the grindstone.

How to sharpen a stainless steel knife

Stainless steel has the characteristic of being extremely hard, but it can be sufficiently sharpened by using a medium whetstone around # 1000. You may also use a manual grindstone called an oil stone that is soaked in oil.

 

If you want to sharpen more “easily” and “safely”, we recommend using a sharpener. Factories such as Leatherman, Victorinox, BUCK, and Mora knife are famous.

 

How to sharpen a steel knife

Since steel is a hard material, choosing a rough whetstone with a high hardness of around # 500 is the key to sharpening efficiently in a short time. Good compatibility with ceramic grindstones made of hard materials. It is important that the surface of the grindstone is firmly flat.

 

How to sharpen a titanium knife

Titanium is a soft metal with low hardness. Therefore, it goes well with soft finishing whetstones from # 1200 to # 3000.

 

For those who are unfamiliar with whetstones, we recommend using a sharpener that anyone can sharpen by simply rubbing. If you sharpen it with a machine, the blade will be shaved back, so be careful not to overdo it.

Please tell me the tips for sharpening both blades.

 

A double-edged blade is one that has a blade on each of the left and right sides. The characteristic of both blades is that the angles of the left and right blades are different. Therefore, the trick is to change the angle at which the blade is laid down on the left and right to sharpen it.

 

If the angle shifts and the angle of the blade is distorted, is it better to custom a new angle with a rough grind?

 

If the angle of the blade is distorted, use a rough whetstone to correct the shape. Scrape off all the cutting edges with a rough whetstone so that the cutting edges are straight. You should do it at an angle of 45 degrees.
