Introducing LDH Midnight Edition 45mm Rotary Blades! They are one of the first black blades in the market! Made out of carbon steel, they are designed with a universal opening so they will fit on other 45mm rotary cutters. Each pack comes with 5 blades. 
 
Material:
They are made out of carbon steel, the same metal and process that is used to make LDH Midnight Edition Fabric Shears. 
 
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 were 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! 
 
Please note: the blades are coated with oil to keep them protected from humidity during transportation. We recommend wiping them off with a scrap piece of cloth before use to avoid staining your project.
