A scissor comprises a rigid blade with a fixed shape and an adjustable spring blade both pinned together at the end of the blade portions. The blades also comprise elongated leg portions extending outwardly from the junction with the blade portions and terminating in curved finger loops or a manipulating handle. The adjustable spring blade comprises a blade with spring like properties of the cutting edge which is continuously maintained in rotation around the fixed axis of the non-cutting edge of said rigid blade. When the scissors are open, the line of the cutting edge of the spring blade penetrates the plane of the opposing blade. This penetration stops when the scissors are closed. The rotation of the spring blade cutting edge may be clockwise or counter-clockwise but is always directed towards the sharp edge of the opposing blade of the scissors and thus continuously engages the sharp edge of the opposing blade at the cutting point.
