The Hultafors Knife Retractable Hi-Vis features an angled design with a pronounced finger grip and narrowing tip, providing excellent grip when measuring and cutting plasterboard in a single stroke. The knife has a durable zinc housing with a screw wheel for easy opening without the need for tools. The handle contains a practical, spring-loaded blade magazine that holds 10 spare blades, each 60mm in length. Changing and cleaning blades is made easy by the few moving parts and magnetic fixings. The blade can be locked in four stages.
