It is important to know

A utility knife with 18 mm snap-off blades makes the most sense for anyone who needs a reliable tool for quickly and accurately cutting a variety of lighter materials for home projects, crafts, or in the workshop. Before purchasing, it's important to consider how often you'll be changing the blade, what materials you'll be cutting, and whether you need additional safety features.

• The break-away blade allows for quick restoration of sharpness, but is slightly less suitable for cutting very hard or thicker materials.
• With frequent use, it is important to check whether changing the blade is easy, as a complicated mechanism can slow down work.
• The shorter blade length (18 mm) allows for more control and precision when cutting, but limits its use with thicker materials.
• For specialized electrical work or rough construction tasks, choose a dedicated knife, as the universal model is not optimized for such tasks.
• The ergonomic handle reduces fatigue during prolonged use, which is important for more intensive projects.
