<p>A hand tool for use in performing manual agricultural grafting, comprises a fixed and a movable handle pivotally connected to each other and having working portions extending beyond the pivot. A coil tension spring connects the first handle to the working portion of the second handle thereby tending to spread the handles apart. The spring is connected to the same point on the working portion of the second handle as is pivotally connected to one end of an arm whose other end is pivotally connected to a positioning fork that locates the stock to be cut. The positioning device slides in a groove on the working portion of the first handle toward and away from a cutting edge carried by the working portion of the first handle.</p> |
