Introducing the Straight Handle 45mm Midnight Edition Rotary Cutter. Each cutter comes with one blade and is packed in a reusable felt bag, eliminating unnecessary plastic packaging.  
 
Design:
This 45mm rotary cutter features a lightweight, straight handle with a quick push-to-release button.  It measures 7.5" from top to bottom. 
 
Blade Durability:
This can vary from person to person and how one uses their cutter, as well as the type of cutting mat they have. LDH blades have been tested at various fabric shops in Toronto, and after using them for up to 8 hours a day, five to seven days a week, each shop got between 3 - 4 months of use from one blade! 
 
Recommended Use:
They can cut through multiple layers of fabric, leather, fleece, vinyl, denim, and other dense materials.
 
This cutter is ambidextrous and can be used in either the right or left hand.
