The 60 degree blue capped blade is a much longer blade and and iswell-suited for cutting thicker materials, such as heavily textured cardstock, chipboard, gum paste, craftfoam, poster board, and rhinestone template material.Blade Installation: The blade must be carefully inserted into the blade holder.

To install, follow the numbered steps as shown: In Step 5, hold the material you are cutting up next to the blade and turn the silver gridded part to adjust theamount of blade protruding.
