The Hakoake Scissors from Kokuyo can be used two ways - as regular scissors or as a box cutter.
Easily switch between two modes with just a gentle squeeze of the handle - "Cutter mode" for opening cardboard boxes with the 3mm blade while the main blades are closed, and "Scissors mode" to cut PP bands or clothing tags.
The guide at the front of the case makes it simple to align to a cardboard box.
