  • Paper knife and staple puller head
    Patent number: 4670926
    Abstract: A paper knife and staple puller head formed by a thin razor type blade having a cutting edge directed towards the interior, and by a non-cutting guide member arranged at a certain angle in front of the cutting edge of the blade. The guide member terminates with an upwardly directed point, thus forming a staple puller. This head can be applied to a handle body of the paper knife type or to a pocketable body of reduced dimensions.
