## Abstract

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.

## Claims

### Claim 1

A cutting tool for grafting comprising first and second members pivotally interconnected at a common pivot, each member including a handle portion on one side of the pivot and a working portion on the other side, the working portion of the second member being connected with the handle portion of the first member via a spring and being also pivotally connected with one end of an arm whose other end is pivotally joined with a movable workpiece locating member slidably guided along the length of the working portion of the first member toward and away from a cutting edge attached to the first member.

### Claim 2 (depends on 1)

A cutting tool for grafting according to claim 1, wherein a groove for slidably guiding the movable workpiece locating member is disposed along the length of the working portion of the first member.

### Claim 3 (depends on 2)

A cutting tool for grafting according to claim 2, wherein the cutting edge is in line with the line of movement of the locating member and the groove is parallel thereto.

### Claim 4 (depends on 1)

A cutting tool for grafting according to claim 1, wherein the workpiece locating member has a longitudinal extension on each side of the cutting edge for separating from the cutting edge pieces cut from the workpiece.
