210 mm replacement saw blade with coarse teeth—for cutting live wood

This replacement blade is designed for pruning fruit trees and other living trees. The large teeth ensure a quick and clean cut, even in harder wood.

The blade is made of high-quality Japanese SK-5 steel and is only 0.75 mm thick. It mounts easily on a compatible saw and is ready to use.

Blade material: Japanese SK-5 steel

SK-5 (SK85) is a high-carbon Japanese steel that, after quenching and tempering, achieves a hardness of 62–63 HRC. It is used for a wide range of cutting tools—from knives and chisels to saws and drill bits.

Edge Retention: Distinctive—the carbon content of nearly 1% ensures excellent cutting edge retention.
Corrosion resistance: Acceptable—regular maintenance is recommended to prevent rust.
Wear resistance: High—thanks to the fine grain size and the carbon carbides in the structure.
Durability: Very good impact resistance with an excellent balance between hardness and strength.
Sharpening: More difficult due to its high hardness, but with the proper technique, a very sharp edge can be achieved.

Frequently Asked Questions

What is this replacement saw blade used for?

The blade is designed for pruning live trees, including fruit trees. The large teeth are specially shaped for cutting live wood, which requires a more aggressive tooth. It is suitable for gardeners and people who regularly work in orchards.

What type of steel is used, and why is that important?

The blade is made of Japanese SK-5 steel, also known as SK85. This is a high-quality, high-carbon steel widely used for cutting tools. After hardening and tempering, it achieves a hardness of 62–63 HRC, which ensures long-lasting edge retention. The steel offers an excellent balance between hardness and impact resistance.

How thick is the blade, and how long is it?

The blade is 0.75 mm thick and 210 mm long. These dimensions are standard for Japanese folding saws designed for gardening. The thin blade reduces friction during cutting and makes the work easier.

Does the SK-5 steel blade require special maintenance?

Yes, the SK-5 is a carbon steel and offers acceptable, though not maximum, corrosion resistance. It is recommended that you clean it regularly and lightly oil it after use. This will protect the blade from rust and significantly extend its life.

Can the blade be sharpened after it becomes dull?

SK-5 steel can be sharpened, but it requires more effort due to the material’s high hardness (62–63 HRC). With the right technique and a suitable sharpener, a very sharp edge can be achieved. For most users, however, it is more practical to replace the blade with a new spare than to sharpen it.

How much does the replacement blade weigh?

The blade weighs only 45 grams, making it extremely lightweight and easy to carry. Its dimensions are 45 x 265 x 3 mm (width, height, thickness of the packaging). Its light weight is an advantage when working in the field or carrying it in a backpack.

Where was the blade manufactured?

The blade is manufactured in Japan—a country with a long tradition of producing high-quality cutting tools. Japanese saws and replacement blades are known for their precision and the quality of their steel. The product is available at Dulotec.COM at a competitive price with fast shipping.
