Olfa SK-4 Self-Retracting Safety Knife

Designed with safety in mind, the Olfa SK-4 has an auto-retracting blade fitted with a powerful and safe return spring for when the thick, stainless steel blade has finished cutting. The ergonomically textured non-slip handle helps to increase grip for better knife control and usage, minimizing the risk of injury whilst cutting as a result.

Perfect for a wide range of environments from domestic to commercial and industrial, the safety knife accommodates both right and left-handed users. With no tools required for blade renewal, every blade replacement is quick and easy.
