Traveling Roller Blade Patents (Class 30/319)
  • Patent number: 10850413
    Abstract: A rotary cutter insert can include a body configured to cover a first portion of a surface of a rotary blade. Further, the body of the rotary cutter insert can have an angled cutout configured to expose a second portion of the surface of the rotary blade so a rotary cutter can be used while the rotary cutter insert is in place. The rotary cutter insert reduces the area of exposed rotary blade that could potentially injure a user, thus making the rotary cutter significantly safer.
