The RECA ultra replacement blades ("black blades") are specially heat treated, creating a higher carbon content in the steel.

Sulphur and manganese content in the alloy is reduced to a minimum. The result: extremely clean-cut edges.

An additional double two-phase section (13° and 25°) and a Rockwell hardness of 65.9 enable more precise coverage and cutting of the material — the result: improved cutting and a longer service life.

Advantages:

• Extremely sharp blade cutting edge
• More precise holding and cutting of the material
• Improved cutting ability
• Longer service life

Content remark:

Box includes 50 blades.
