Abstract

A combination precision knife and blade dispenser having a handle portion configured to receive a blade and a dispenser. The dispenser is configured to support at least one blade in a new blade portion thereof. The dispenser further has a used blade portion configured to support at least one blade therein, where a user, manipulates the handle portion and engages a base of the at least one blade therein, and where in order to dispose of the blade, the user inserts the blade into the dispenser and disengages the base of the blade from the handle portion such that at no time does a user need to touch an edge portion of the blade.

Claims

1. A combination precision knife and blade dispenser, said combination comprising:

a handle portion configured to receive a blade; and

a dispenser, said dispenser configured to support at least one blade in a new blade portion thereof, said dispenser further having a used blade portion configured to support at least one blade therein, wherein a user, manipulates said handle portion and engages a base of said at least one blade therein, and wherein in order to dispose of said blade, said user inserts said blade into said dispenser and disengages said base of said blade from said handle portion such that at no time does a user need to touch an edge portion of the blade.

2. The invention as claimed in claim 1, wherein said handle portion maintains a sliding blade assembly therein, moveable between a first retracted position and a second forward position.

3. The invention as claimed in claim 2, wherein said sliding blade assembly has a threaded blade opening for engaging said blade.

4. The invention as claimed in claim 3, wherein said base of said blade has a threaded base.

5. The invention as claimed in claim 1, wherein said new and used sections of said dispenser have openable covers.

6. The invention as claimed in claim 1, wherein said sliding blade assembly is moved to said second forward position using an activation knob that protrudes from the rear of said handle portion through an upper slot.

7. The invention as claimed in claim 6, wherein a spring is positioned between a blocking flange within said handle portion and a spring catch notch on said sliding blade assembly in order to bias said sliding blade assembly in a rearward direction.

8. The invention as claimed in claim 1, wherein said dispenser further comprises at least one blade support, configured to hold said at least one blade in position within said dispenser.

9. The invention as claimed in claim 1, wherein within said dispenser, said edge portion of said blade is protected by a safety wall such only said base portion of said blade is accessible by touch.

10. A combination precision knife and blade dispenser, said combination comprising:

a handle portion, said handle portion having a sliding blade assembly therein moveable between a first retracted position and a second forward position, said blade assembly having a blade opening; and

a dispenser, said dispenser configured to support at least one blade in a new blade portion thereof, said dispenser further having a used blade portion configured to support at least one blade therein, wherein a user manipulates said sliding blade assembly to said second forward position and engages a base of said at least one blade into said blade opening in order to insert said blade into said handle portion, and wherein in order to dispose of said blade, said user inserts said blade into said dispenser and disengages said base of said blade from said blade opening.

11. The invention as claimed in claim 10, wherein said sliding blade assembly has a threaded blade opening for engaging said blade.

12. The invention as claimed in claim 11, wherein said base of said blade has a threaded base.

13. The invention as claimed in claim 10, wherein said sliding blade assembly is moved to said second forward position using an activation knob that protrudes from the rear of said handle portion through an upper slot.

15. The invention as claimed in claim 10, wherein a spring is positioned between a blocking flange within said handle portion and a spring catch notch on said sliding blade assembly in order to bias said sliding blade assembly in a rearward direction.

16. A combination precision knife and blade dispenser, said combination comprising:

a handle portion, said handle portion having a sliding blade assembly therein moveable between a first retracted position and a second forward position, said blade assembly having a threaded blade opening; and

a dispenser, said dispenser configured to support at least one blade in a new blade portion thereof, said dispenser further having a used blade portion configured to support at least one blade therein, wherein a user opens said new blade portion, manipulates said sliding blade assembly to said second forward position, and screws a threaded base of said at least one blade into said threaded blade opening in order to insert said blade into said handle portion, and wherein in order to dispose of said blade, said user opens said used blade portion of said blade dispenser, inserts said blade into said dispenser and unscrews said threaded base of said blade from said threaded blade opening.

17. The invention as claimed in claim 16, wherein said blade has a first edge portion and a second screw base portion.

18. The invention as claimed in claim 17, wherein within said dispenser when opened, said edge portion is protected by a safety wall such only said screw base portions is accessible by touch.

19. The invention as claimed in claim 16, wherein said sliding blade assembly is biased in said first retracted position by a spring within said handle portion.

20. The invention as claimed in claim 19, wherein said sliding blade assembly is moved to said second forward position using an activation knob that protrudes from the rear of said handle portion through an upper slot.

21. The invention as claimed in claim 20, wherein said spring is positioned between a blocking flange within said handle portion and a spring catch notch on said sliding blade assembly.

22. A method for operating a combination precision knife and blade dispenser, said method comprising the step of:

activating a sliding blade assembly to a second forward position from a first retracted position within a handle portion of said knife, said assembly having a forward blade opening;

engaging a new blade portion of a dispenser containing at least one knife therein, said knife having an edge portion and a base portion, wherein only said base portion is exposed;

attaching said base portion of said blade into said forward blade opening;

removing said blade from said dispenser;

wherein when said edge portion of said blade is dull from use or otherwise;

inserting said edge portion of said blade into said used blade portion of said dispenser; and

disengaging said base portion of said blade from said forward blade opening, such during the entire method for operating a combination precision knife and blade dispenser, a user need not touch said edge portion of said blade.
