Japanese SK-85 Steel – Properties and Advantages

After quenching and tempering, SK-85 steel acquires high hardness and wear resistance. It is used to manufacture a wide range of cutting tools—from scalpels and razor blades to axes, chisels, and hand saws.

Holding the Edge

A carbon content of nearly 1% makes this steel very hard. The result is excellent edge retention during prolonged use.

Corrosion Resistance

Steel offers acceptable corrosion resistance. Regular maintenance is recommended to prevent rust from forming.

Wear Resistance

The fine grain and carbon carbides ensure high wear resistance. The blade retains its shape and performance even during intensive use.

Sharpness and Sharpening

SK-85 can achieve a hardness of 62–63 HRC. The harder the steel, the more difficult it is to sharpen—and that holds true here as well.

Durability

Steel offers a good balance between hardness and impact resistance. This makes it a reliable choice for woodworking in real-world conditions.

How long is the blade?

The cutting edge is 120 mm long and 0.7 mm thick. The overall dimensions of the product are 50 × 210 × 3 mm.

What kind of steel is the blade made of?

The blade is made of Japanese SK-85 high-carbon steel. It is characterized by high hardness, good edge retention, and high wear resistance.

Can the blade rust?

SK-85 steel offers acceptable, but not complete, corrosion resistance. It is recommended to clean and lubricate the blade regularly after use, especially in wet conditions.

How hard is SK-85 steel?

After heat treatment, SK-85 steel can achieve a hardness of 62 to 63 HRC. This high hardness ensures excellent edge retention, but makes sharpening more difficult compared to softer steels.
