A rotary cutter is how quilters cut clean, straight strips and gentle curves through several fabric layers at once. The 45mm blade is the quilting standard, big enough for long cuts yet controllable, and you only drop to a 28mm blade for tight curves.

Blades are razor sharp, so prefer an auto-retract or a positive lock, and remember a cutter is only useful with a self-healing mat and a thick acrylic ruler.
