What is the blade angle of a utility knife?

There are many blade angles for utility knives, the most common ones are 30°, 45°, and 60°. The 30° blade angle is suitable for cutting thinner materials such as paper, tape, and cardboard, while the 45° blade angle is suitable for cutting thicker materials such as foam boards and wooden materials. The 60° blade angle of the utility knife is suitable for cutting stickier materials such as double-sided tape and magnetic materials, and is also suitable for cutting details. In addition, there are some special utility knives, such as the Japanese OLFA 10BS (AK-1) pen-shaped craft knife, which has a blade angle of 32.8° and is suitable for delicate work. Choosing the right blade angle depends on the specific usage requirements and material type.
