Abstract

A cutting hand tool which allows easy cutting of thin materials, such as film, paper, packaging or other flexible materials even if the material is folded or stretchy such as shrink- or stretch-wrap, without requiring a strong force, while at the same time protecting the user from injuries. The cutting blade is placed in a recess to prevent accidents and can be rotated or laterally moved by activating a trigger so that an additional force can be applied to cut the material whenever this is required to continue the cutting motion, when the material is rolled over, folded, bunched or reinforced and therefore requires an additional cutting force.

Claims

1. A cutting hand tool comprising

a housing,

consisting of a handle and

a front part

said front part

containing a narrow recess,

a blade holder,

mounted in said front part,

allowing movement of the blade edge between a first and a second position

an arrangement

forcing the blade holder into said first position,

a trigger button,

wherein

activating the trigger button forces said blade holder into a second position by moving the blade holder and with it the cutting blade such that the cutting edge of the blade moves at least partially in a direction other than the direction along the cutting blade edge.

2. The cutting hand tool of claim 1 wherein

said blade holder movement is by rotation around a pivot point.

3. The cutting hand tool of claim 1 wherein

said blade holder movement is by translation of the cutting blade.

4. The cutting hand tool of claim 1 wherein

said arrangement consists of at least one spring.

5. The cutting hand tool of claim 1 wherein

said arrangement consists of at least one magnet.

6. The cutting hand tool of claim 1 wherein

said narrow recess points towards the rear of the cutting tool to enable a cutting motion towards the operator

7. The cutting hand tool of claim 1 wherein

said narrow recess points towards the front of the cutting tool to enable a cutting motion away from the operator.

8. The cutting hand tool of claim 1 wherein

said arrangement consists of a mechanism for automatically moving the blade holder between the first and second position and said trigger button is used to start and stop the automatic movement.

9. The cutting hand tool of claim 8 wherein

the frequency of said movement of the blade holder between the first and second position is variable and can be adjusted.

10. The cutting hand tool of claim 8 wherein

the travel distance of the blade holder between the first and second position is variable and can be adjusted.

11. The cutting hand tool of claim 8 wherein

said mechanism includes a motor.

12. The cutting hand tool of claim 8 wherein

said mechanism includes an electromagnet.
