A hand tool for cutting elongated materials comprising,
- an elongated body portion having a forward end, a rear end and a clamping jaw supporting extension,
- an elongated saw blade supporting element having a handle portion and being pivotally mounted on the body portion adjacent the rear end of said portion, for movement of said blade supporting element in a plane perpendicular to its pivoting axis,
- an elongated saw blade,
- means connecting said blade to the blade supporting element,
- means for effecting cutting motion of the blade in said perpendicular plane relative to the blade supporting element,
- a first clamping jaw adjustably mounted on said jaw supporting extension,
- a clamping lever comprising an elongated handle portion and at least one forwardly positioned second clamping jaw means, and
- means pivotally mounting said lever on the body portion adjacent the forward end thereof,
- the body portion, the handle portion of the blade supporting element and the handle portion of the clamping lever being so juxtaposed that they can be grasped by one hand of a tool operator for simultaneously clamping the work and biasing the saw blade toward said work in a cutting plane perpendicular to the pivoting axis of the blade supporting element.
