Replacement blades are available as standard blades made of high-quality stainless steel for all Prym rotary cutters and can be easily reordered at any time. The wavy blades and serrated blades, which are also durable, can be used for the Prym Maxi and Maxi Easy, Comfort rotary cutters, Multi rotary cutters and the Omnicut rotary cutters. The securely packaged blades should be replaced regularly because blunt blades lead to fatigue, inaccurate cuts and damage the cutting mat. Replacement should be done with care as the blades are extremely sharp.
