## Description

45mm ergonomic rotary cutter

Review: Best easy to use rotary cutter! - Love this cutter! Easy to lock and open. And I love how the blade engages as you start to cut. Once you stop cutting the blade automatically is protected. The handle is nice and thick. Easy for arthritic hands. Highly recommended!
Review: My favorite rotary cutter - This is my absolute favorite rotary cutter. It’s good for a left hand or right hand. The best part about it is that it’s never left open. The blade is exposed only when you apply pressure onto your rotary board. I actually own three of these. Highly recommend, particularly for someone who always leaves their rotary cutter open after use.
