Tersa HSS Knife Black Oxide – 640x10x2,3

• Special Black Oxide coating for long blade life and durability.
• Tersa reversible planing knife suitable for Tersa clamping systems.
• High quality blades for planing soft and hard solid wood.
• Smooth and clean surface thanks to maximum sharpness.

The Black Oxide planing knives are made of high quality HSS steel with Black Oxide coating, which gives these knives a much higher durability and service life than conventional HSS steel knives.
The cutting edges are hardened while the core of the knife remains soft. This results in high edge hardness and toughness of the entire knife, which is more resistant to breakage.
