Abstract

A method for manufacturing a safety/rescue knife requires the forming of four blank laminates. Each blank laminate has a handle portion and includes a base arm which is attached to the handle portion. Also, each blank laminate has an extension arm which extends from the base arm to define a groove therebetween. One blank laminate is further formed with a cut out in its base arm, and another blank laminate is further formed with a cut out in its extension arm. The method then requires aligning each of the cut out laminates with a respective blank laminate to create blade recesses. Next, cutting blades are placed in the recesses, and the cut out laminates are juxtaposed in alignment. The blank laminates are then connected together to hold the inner laminates and the blades therebetween with the blades crossed to establish a cutting angle in the groove.

Claims

1. A method for manufacturing a safety/rescue knife which comprises the steps of:

positioning a left inner laminate in alignment over a left outer laminate to create a first blade recess;

positioning a right inner laminate in alignment over a right outer laminate to create a second blade recess;

placing a first blade in said first blade recess;

placing a second blade in said second blade recess;

juxtaposing said left inner laminate in alignment with said right inner laminate; and

connecting said left outer laminate to said right outer laminate to hold said first blade in said first blade recess against said second blade in said second blade recess.

2. A method as recited in claim 1 further comprising the step of crossing said first blade over said second blade during said juxtaposing step to create a cutting angle.

3. A method as recited in claim 1 further comprising the step of forming said left inner laminate and said right inner laminate with a respective opening, said openings being formed to cooperatively establish a blade storage compartment during said juxtaposing step.

4. A method as recited in claim 1 wherein said connecting step is accomplished by bolting.

5. A method as recited in claim 1 wherein said left outer laminate, said left inner laminate, said right outer laminate and said right inner laminate are each formed with a respective base arm and with an extension arm, each said extension arm being oriented relative to each respective said base arm to define a groove therebetween.

6. A method as recited in claim 5 further comprising the steps of:

forming a cut out into said base arm of said left inner laminate to create said first blade recess; and

forming a cut out into said extension arm of said right inner laminate to create said second blade recess.

7. A method as recited in claim 5 further comprising the step of crossing said first blade over said second blade during said juxtaposing step to create a cutting angle therebetween in said groove.

8. A method as recited in claim 5 further comprising the step of forming said left inner laminate and said right inner laminate with a respective opening, said openings being formed to cooperatively establish a blade storage compartment during said juxtaposing step.

9. A method as recited in claim 5 wherein said connecting step is accomplished by bolting.

10. A method for manufacturing a safety/rescue knife which comprises the steps of:

forming a plurality of blank laminates, each said blank laminate having a handle, a base arm attached to said handle, and an extension arm extending from said base arm and oriented therewith to define a groove therebetween;

creating a left inner laminate from one of said blank laminates, said left inner laminate being created by forming a cut out into said base arm thereof;

creating a right inner laminate from one of said blank laminates, said right inner laminate being created by forming a cut out into said extension arm thereof;

juxtaposing said left inner laminate in alignment against said right inner laminate;

placing a first blade in said cut out of said left inner laminate and a second blade in said blade placed in said cut out of said right inner laminate to establish a cutting angle between said first and second blades; and

connecting one said blank laminate in alignment with another said blank laminate to hold said left inner laminate and said right inner laminate therebetween with said cutting angle in said groove.

11. A method as recited in claim 10 further comprising the step of forming said left inner laminate and said right inner laminate with a respective opening, said openings being formed to cooperatively establish a blade storage compartment during said juxtaposing step.

12. A method as recited in claim 10 wherein said connecting step is accomplished by bolting.
