Midori Rounded Ceramic Carton Cutter

Compact and minimal, this ceramic cutter slices through boxes, sheets of paper, or letters in one easy swipe. The blade is made by Kyocera, the ceramic knife and blade manufacturer — durable and rust-proof, unlike metal blades. The fibreglass body protects your fingers and the blade, and its magnetic back makes it easy to store.

Adjust the cutter to how deep you need it to cut, and use an angle when slicing into a thin sheet of paper.
