Cut could not be easier

90% Magnetic Scissors, designed by Sang-in Lee & Yun-je Sung. The scissor-head houses power-magnets in their internal seam, which uses the repel action to cut an easy snip. You also can change the poles at the flick of a button, to keep the blades locked into place. Apparently 90% of the force used for cutting is sourced from the magnetic power, and 10% comes from your end.
