What is a powder high-speed steel knife? Why is it called a "super bla

In addition to stainless steel and steel, knives are made from powdered high-speed steel , which has been gaining attention in recent years.

What makes this steel, which boasts the sharpness and durability of a superalloy, different from conventional knives?
We will provide easy-to-understand explanations of the manufacturing process, features, and tips for everyday use.

What is powdered high-speed steel?

High-speed steel is a hard steel material that was originally used for high-speed cutting tools. It is characterized by the addition of tungsten, molybdenum, vanadium, etc. to iron, which improves its heat resistance and wear resistance. Powdered high-speed steel is made by further powdering this high-speed steel and solidifying it under high pressure. Unlike traditional casting methods, the particles can be made finer, making it easier to make the steel structure uniform, achieving high levels of both hardness and toughness.

Why is it so high performance? The secret behind powdered high-speed steel

Uniform particle size: The powder metallurgy manufacturing process allows the components to be dispersed uniformly, resulting in less unevenness and a sharper cutting edge than conventional high-speed steel.
Resistant to wear: The blades retain their sharpness after sharpening because, in addition to their high hardness, they have a crystalline structure that makes them resistant to wear.
High heat resistance: It has the property of minimizing damage to the blade edge even when exposed to heat generated during processing or cooking.

More than just benefits? Challenges with powder high-speed steel knives

Because they are expensive and the manufacturing process is complex and requires advanced skills, the market price is often higher than that of ordinary stainless steel knives.
Care must be taken when sharpening . Because the HRC rating is high (63-66), choosing the right whetstone and sharpening techniques are important. If you are not used to it, chipping or uneven sharpening may occur.

Things to be careful of in daily use

- Determine the use. For ingredients that will be subjected to more stress than usual, such as hard pumpkins, meat with bones, and frozen foods, it is recommended to use a knife such as a deba knife.

Regular maintenance: Powdered high-speed steel tends to be rust-resistant, but that doesn't mean it requires no maintenance. Wiping off moisture after use and occasionally sharpening the cutting edge will help extend its life.

*Stainless steel PM-HSS with a chromium content of 14% or more, such as SG2/R2, has excellent rust resistance, but semi-stainless steel such as HAP40 is prone to rust when exposed to moisture or acid, so care must be taken.

On the other hand, for those who prioritize ease of use and maintenance, there are options such as Tashinam 's Perfect Knife .
