Irwin Standard Retractable Knife

This Irwin Standard Retractable Knife 8 general-purpose Standard Retractable Knife has a lightweight, but hard-wearing aluminium body to hold up on the job. A magnet holds the working blade in place, and a captive screw prevents loss during blade change.
The quick-change mechanism allows for easy blade removal, or reversal, without opening the knife, which has a durable, 3-position slide allowing different blade lengths to be used.
There is a one touch easy access to spare blades and the tough construction is designed to fit the hand comfortably when in use.
