Cutting tools

A cutting tool comprising:

• a rod reciprocating in an axial direction of the rod;
• and
• a blade mounting device configured to mount a blade to the rod, the blade being configured to have a shape of a band plate having a width, and the blade including a head and engaging lugs on opposite sides in a direction of the width, the blade mounting device comprising:
• an operation member operable to rotate between a blade mounting position and a blade removing position about an axis of the rod and biased toward the blade mounting position by a first biasing device;
• a blade holder disposed within the operation member and integrated therewith, and
• a blade guide movable relative to the rod between a restricting position and a non-restricting position in an axial direction of the rod, the blade guide being prevented from rotating about an axis and biased toward the non-restricting position by a second biasing device, wherein:
• the blade guide permits rotation of the operation member toward the blade mounting position as the blade guide moves toward the non-restricting position against a biasing force of the second biasing device, and the blade guide holds the operation member at the blade removing position when the blade guide returns to the restricting position;
• the blade holder engages the engaging lugs of the blade to prevent movement of the blade in a removing direction when the operation member moves to the blade mounting position, and the blade holder allows movement of the blade when the operation member is operated to rotate to the blade removing position;
• and
• the blade guide has a substantially cylindrical configuration and includes a V-shaped guide recess formed along a diametrical direction of the blade guide for guiding the head of the blade.
