Abstract

A knife has plastic molded body with a handle and distal portion formed with finger-like extensions that hold a blade with its cutting edges exposed. The extensions form an atraumatic profile with the blade to facilitate cutting of an object by the cutting edge. The atraumatic profile extends along a longitudinal direction of the knife and/or a lateral direction of the knife. In one embodiment, the extensions are tapered in both a longitudinal and a lateral direction of the knife, such that there is a smooth transitional region where the extensions and the blade meet. The knife includes a sliding region proximal the cutting edge of the blade which facilitates a swift cutting motion into dough where the extensions follow and functions as part of the blade. The knife also includes a protective cover that is detachable from the knife, or is movable between a position that covers the blade and a position that exposes the blade. The cover can translate or pivot between the two positions by means of pins that engage a slot formed in the handle. The cover can releasably lock in both positions by means of a latch mechanism. The knife may also include an orientation indicator.

Claims

1. A knife, comprising:

a body with a handle, and a distal portion having extensions; and

a blade positioned between the extensions, the blade have at least one cutting edge;

wherein the extensions form an atraumatic profile with the blade to facilitate cutting of an object by the cutting edge.

2. A knife of claim 1, wherein the atraumatic profile extends along a longitudinal direction of the knife.

3. A knife of claim 1, wherein the atraumatic profile extends along a lateral direction of the knife.

4. A knife of claim 1, wherein the extensions are tapered in both a longitudinal and a lateral direction of the knife.

5. A knife of claim 1, wherein the blade is a double edge razor blade.

6. A knife of claim 1, further comprising a cover.

7. A knife of claim 6, wherein the cover is movable between a first position that covers the cutting edge and a second position that exposes the cutting edge.

8. A knife of claim 7, wherein the cover translates along a longitudinal direction between the first and second positions.

9. A knife of claim 7, wherein the cover is detachable from the knife.

10. A knife of claim 1, further comprising an orientation indicator.

11. A knife of claim 1, wherein the blade is planar.

12. A knife of claim 1, wherein the blade is curved.

13. A knife of claim 7, wherein the handle has a slot and the cover has at least one pin to engage the slot for guiding movement of the cover between the first and second positions.

14. A knife of claim 6, further comprising a latch mechanism to releasably lock the cover in a position on the handle.

15. A knife of claim 1, wherein the handle is generally of an oval configuration.

16. A knife of claim 1, wherein the handle is generally of an elongated linear configuration.

17. A knife of claim 1, wherein the handle is generally of a elongated contoured configuration.

18. A knife of claim 1, wherein the body is of molded plastic.

19. A knife of claim 18, wherein the blade is molded in the plastic.

20. A knife of claim 1, wherein the knife is adapted for scoring dough.

21. A knife of claim 1, further comprising a sliding region proximal at least an exposed cutting edge of the blade.
