Utility Knife Safety Tips
Always wear safety glasses when using utility knives. Blades can snap off unexpectedly.
Always use sharp blades. Dull blades are a safety hazard, requiring more force to make the cut, which can lead to tool slippage.
Always pull the knife toward you when cutting, and make several passes when cutting thicker materials.
To prevent slippage, make sure blades are seated properly in the knife.
Never leave a utility knife unattended, especially with the blade exposed
