Claims11
A utility knife, comprising:
- a handle;
- a blade holder connected to the handle by means that is movable about at least two axes for connecting the blade holder to the handle for movement in a single curvilinear path relative to the handle between a retracted position and an extended position;
- a button assembly that is moveable along a transverse linear path with respect to the handle and that cooperates with the blade holder to move the blade holder to the extended position;

- a handle;
- a blade holder connected to the handle by means that is movable about at least two axes for connecting the blade holder to the handle for movement in a curvilinear path relative to the handle between a retracted position and an extended position with a top surface of the blade holder maintaining a substantially consistent perpendicular orientation with respect to a right side of the handle;
- and
- a utility blade replaceably attached to the blade holder for selective removal and replacement of the utility blade.
