The rotary cutter has a button that toggles to the left or right to expose the blade. Push and move the button a quarter circle in either direction until it clicks in place. When not in use, move the button to the center position to protect the blade.
The exposed blade is specifically designed to extend beyond the guard to work with the Creative Grids® slotted rulers. To replace the blade, simply pull down on the tab to release it and add a new blade – a one-step process.
The Creative Grids® 45mm rotary cutter comes with a protective zippered case that includes plenty of room to store additional blades and notions.
