The present invention relates to rounded blade scissors. The rounded blade scissors according to one embodiment of the present invention comprise: a first cutting portion including a first cutting blade bent in one direction to cut a target; a second cutting portion including a second cutting blade having a closed annular or polygonal shape to surround the surface of the first cutting portion; a first frame portion supporting the first cutting portion on one side of the first cutting portion; a second frame portion supporting the second cutting portion on one side of the second cutting portion; and a coupling portion that hingedly couples the first frame portion with the second frame portion so that the first cutting portion comes into contact with the second frame portion through rotation. Therefore, the cutting can be performed in a safe and effective manner. According to the present invention, the cutting target can be cut in an easy, convenient, and safe manner.

A hand-operated ratchet cutter with a movable and a fixed handle, wherein the fixed handle forms a first fixed blade, and a movable blade is hinged to an upper end area of the fixed blade, for shearing interaction in a cutting plane with the fixed blade. The movable blade moves in a plane parallel to the cutting plane, and the fixed blade has a first flat side. A fixed jaw with a second flat side (21) facing the first flat side is formed that also extends up to the upper end area of the fixed blade. A passage slot for the movable blade adjusted to the thickness (d) is formed between the first and second flat side, so as to ensure the shearing interaction between the movable and fixed blade even under a load by having the jaw act as a supporting jaw.

Provided is a pair of scissors, which can cut an object efficiently with lighter force, and makes it easy to cut a cardboard and the like since the pin joint does not hinder the cutting. The pair of scissors comprises: a first handle portion operated by a thumb; a second handle portion operated by other fingers; a first blade portion which connects to the first handle portion; and a second blade portion which connects to the second handle portion; first and second protruding portions which protrude the first blade portion and the second blade portion to the second handle portion side from a position where the first blade portion and the second blade portion intersect each other; and a pin joint that rotatably joins both of the first protruding portion and the second protruding portion to each other.

The present invention provides scissors obtained by selecting materials sliding against each other, utilizing their springiness, enabling the shape of a blade to be followed so that a shear blade slides against the opposite shear blade, and can cut along the opposite blade. The present invention relates to scissors for medical use comprised of a pair of shanks with one ends forming an upper shear blade and a lower shear blade and with the other ends of the pair of shanks forming handles, the handles being opened and closed centered about a pivot where the shanks intersect and causing the upper shear blade and lower shear blade to open and close, at least one of the upper shear blade and the lower shear blade being formed by an alloy having an elastic deformation ability of 0.2% or more.

The invention relates to a manual cutting tool (110), comprising two arms (112) hinged about an axis (X), each arm comprising a first portion (114) to enable said tool to be grasped by a user and a second cutting portion (116), said first and second portions being separated from one another by said axis, the second portions of the arms comprising cutting edges (118) that define a cross-sectional area (A) of an element to be cut, the tool being configured such that a hinge on the arms about said axis brings the cutting edges of the arms together and cuts said element. The invention is characterized in that it further comprises a member (130) for protecting the user, which is made of a transparent material, said member extending substantially in parallel with said cross-sectional area and covering same completely, and being flexible in a plane substantially perpendicular to said cross-sectional area.
