The transmission forms of utility knives are manual transmission and automatic transmission.
1. The manual transmission utility knife is the most common type. It uses a manual rotating blade to complete the cutting process. The blade of a manual utility knife is usually detachable, and users can replace the blade with different shapes as needed to adapt to different cutting needs. Manual utility knives are suitable for simple cutting and engraving tasks that do not require high precision.
2. An automatic transmission utility knife uses an electric motor or battery to drive the blade to rotate to complete the cutting process. Compared with manual utility knives, automatic utility knives have higher cutting accuracy and efficiency, and are suitable for some fine, high-precision cutting and engraving work. At the same time, automatic utility knives also have more functions, such as automatic knife sharpening, automatic tool changing, etc.
