Abstract
A utility knife has a handle and a replaceable blade fixed to the handle. The blade has a cutting edge extending from the handle along an axis for a distance. The utility knife includes a movement mechanism, which may be at least partially enclosed by the handle. The movement mechanism is adapted to provide reversible motion along relative to the blade. A shield is connected to the movement mechanism and disposed adjacent to the blade, whereby the shield is movable between an extended position covering the cutting edge and a retracted position exposing the cutting edge. When in a retracted position, the shield may be inside or closely adjacent to the handle, so as to not interfere with handling of the knife.
Claims29
A utility knife, comprising:
- a handle;
- a blade fixed to the handle, having a cutting edge extending from the handle for a fixed distance;
- a movement mechanism mounted to the handle, the mechanism adapted to provide reversible motion relative to the blade;
- and
- a shield connected to the movement mechanism and disposed adjacent to the blade, whereby the shield is movable between an extended position covering the cutting edge and a retracted position exposing the cutting edge.
A utility knife, comprising:
- a handle;
- a blade fixed to the handle, having a cutting edge extending from the handle along an axis for a distance;
- a linear movement mechanism at least partially enclosed by the handle, the mechanism adapted to provide reversible motion along the axis over the distance;
- and
- a shield connected to the linear movement mechanism and disposed adjacent to the blade, whereby the shield is movable between an extended position covering the cutting edge and a retracted position exposing the cutting edge.
A utility knife, comprising:
- a handle;
- a blade fixed to the handle, having a cutting edge extending from the handle along an axis for a distance;
- a shield disposed adjacent to the blade;
- and
- reversible movement means for moving the shield along the axis over the distance, the reversible movement means disposed inside the handle and connected to the shield, whereby the shield is movable between an extended position covering the cutting edge and a retracted position exposing the cutting edge.
