Abstract

A knife includes a knife body having two liners and a blade positioned between the two liners. The knife further includes two scales, each scale being removably coupled to one of the two liners. Each scale is configured for use as a tool separate from the knife body when removed from the knife body. A bottle opener may be formed in the knife body.

Claims (41)

1. A knife, comprising:

a knife body, comprising:

two liners;

a blade positioned between the two liners;

two scales, each scale removably coupled to one of the two liners;

wherein each scale is also a tool usable separate from the knife body when removed from the knife body;

wherein a bottle opener is formed in the knife body;

wherein the blade is rotatably coupled to the two liners proximate a first end of each of the two liners, and the bottle opener is formed from a lock back catch and a spring spacer positioned between the two liners;

wherein each liner includes a cutout proximate a second end of the liner, wherein a hook of the lock back catch is accessible via the cutouts, wherein a protrusion of the spring spacer is accessible via the cutouts; and

wherein the hook and the protrusion are arranged so that the bottle opener operates with the hook engaged with a lip of a bottle cap and with the protrusion in contact with a top surface of the bottle cap as a rotation point, so that rotation of the knife removes the bottle cap from a bottle.

2. The knife of claim 1 , wherein the tool is a tire lever.

3. The knife of claim 1 , wherein each scale is magnetically coupled to one of the two liners.

4. The knife of claim 1 , wherein at least one of the scales includes a pocket clip.

5. A knife, comprising:

two liners;

a blade positioned between the two liners and rotatably coupled to the two liners proximate a first end of each of the two liners;

a lock back catch positioned between the two liners; and

a spring spacer positioned between the two liners proximate a second end of each of the two liners;

wherein a bottle opener is formed by the lock back catch and the spring spacer.

6. The knife of claim 5 , wherein the lock back catch includes a hook and the spring spacer includes a protrusion, wherein the hook and the protrusion are arranged so that the bottle opener operates with the hook engaged with a lip of a bottle cap and with the protrusion in contact with a top surface of the bottle cap as a rotation point, so that rotation of the knife removes the bottle cap from a bottle.

7. A knife, comprising:

a knife body, comprising:

two liners; and

a blade positioned between the two liners and rotatably coupled to the two liners proximate a first end of each of the two liners; and

two scales, each scale removably coupled to one of the two liners;

wherein each scale is also a tool usable separate from the knife body when removed from the knife body.

8. The knife of claim 7 , wherein the tool is a tire lever.

9. The knife of claim 7 , wherein each scale is magnetically coupled to one of the two liners.

10. The knife of claim 9 , wherein each scale includes a magnet and at least a portion of each liner is ferromagnetic.

11. The knife of claim 9 , wherein each liner includes a magnet and at least a portion of each scale is ferromagnetic.

12. The knife of claim 7 , wherein each scale includes a protrusion and each liner includes a corresponding recess, wherein each protrusion is received by the corresponding recess when the scale is coupled to the liner.

13. The knife of claim 7 , wherein each liner includes a protrusion and each scale includes a corresponding recess, wherein each protrusion is received by the corresponding recess when the scale is coupled to the liner.

14. The knife of claim 7 , wherein at least one of the scales includes a pocket clip.

15. The knife of claim 3 , wherein each scale includes a magnet and at least a portion of each liner is ferromagnetic.

16. The knife of claim 3 , wherein each liner includes a magnet and at least a portion of each scale is ferromagnetic.

17. The knife of claim 1 , wherein each scale includes a protrusion and each liner includes a corresponding recess, wherein each protrusion is received by the corresponding recess when the scale is coupled to the liner.

18. The knife of claim 1 , wherein each liner includes a protrusion and each scale includes a corresponding recess, wherein each protrusion is received by the corresponding recess when the scale is coupled to the liner.

19. The knife of claim 7 , further comprising:

a lock back catch positioned between the two liners; and

a spring spacer positioned between the two liners proximate a second end of each of the two liners;

wherein a bottle opener is formed by the lock back catch and the spring spacer.
