What is the angle of the blades for cutters?

The angle of the blades for cutters is typically set at 30 degrees. This angle strikes a balance between cutting efficiency and the durability of the blade. A 30-degree angle allows for effective penetration into materials while providing sufficient surface area for the blade to withstand wear and tear during use.

Blades set at a steeper angle, such as 25 degrees, may not provide the same level of durability as a 30-degree setting, leading to quicker dulling. Conversely, angles like 35 and 40 degrees can offer more strength but may hinder cutting effectiveness and require more force to use, making them less optimal for general cutting tasks. The 30-degree angle is thus favored in many applications for its combination of sharpness and longevity.
