Abstract

A tool for steeling a knife includes a frame and first and second steeling components. Each of the components is shiftably mounted relative to the frame for movement between a first position and a second position. The steeling components cooperatively define a knife interface configured to engage and thereby steel the knife. The steeling components are resiliently biased into the first position, with the knife interface moving as the steeling components shift between the first and second positions.

Claims (109)

1. A tool for steeling a knife, the tool comprising:

a frame;

a first steeling component and a second steeling component, each being shiftably mounted relative to the frame for movement between a first position and a second position,

said steeling components cooperatively defining a knife interface configured to engage and thereby steel the knife,

said steeling components being resiliently biased into the first position, with the knife interface moving as the steeling components shift between the first and second positions; and

a stop stationary relative to the frame,

said stop engaging the first steeling component when in the first position and engaging the second steeling component when in the second position.

2. The tool of claim 1 ,

said stop presenting a first component-engaging surface configured to contact the first steeling component and a second component-engaging surface configured to contact the second steeling component.

3. The tool of claim 2 ,

said component-engaging surfaces being angled relative to one another.

4. The tool of claim 1 ,

a second stop spaced from the first-mentioned stop,

said second stop being stationary relative to the frame,

said second stop engaging the first steeling component when in the second position and engaging the second steeling component when in the first position.

5. The tool of claim 4 ,

said frame including spaced apart first and second support members,

each of said stops being fixed relative to a corresponding one of the support members.

6. The tool of claim 5 ,

each of said stops being integrally formed with the corresponding one of the support members.

7. The tool of claim 5 ,

said first steeling component being supported by the first support member,

said second steeling component being supported by the second support member.

8. The tool of claim 7 ,

said first and second support members defining an elongated slot therebetween,

said knife interface being aligned with and moving along the slot.

9. The tool of claim 1 , further comprising:

a first steeling component assembly including the first steeling component; and

a second steeling component assembly including the second steeling component,

each of said steeling component assemblies including a post rotatably coupled to the frame,

said respective post being interconnected to the respective steeling component for rotation therewith, with the respective post serving to support the respective steeling component on the frame.

10. The tool of claim 9 ,

each of said steeling component assemblies including a spring operably intercoupled between the respective post and the frame to resiliently bias the respective steeling component into the first position.

11. The tool of claim 10 ,

each spring comprising a coil extending between opposite first and second ends, with the first end

being secured to the respective post and the second end being secured to the frame, said respective post presenting a flanged portion,

said coil encircling the flanged portion.

12. The tool of claim 11 ,

said frame including spaced apart first and second support members,

said respective post being secured to a respective one of the support members,

said second end of the respective spring being secured to the respective one of the support members.

13. The tool of claim 12 ,

each supporting member defining an aperture,

said flanged portion of the respective post and said coil of the respective spring being located within the aperture of the respective one of the support members.

14. The tool of claim 13 ,

each of said steeling component assemblies including a fastener that extends into the aperture and is connected to the respective post.

15. The tool of claim 1 ,

said frame including a handle configured to be grasped by a user.

16. The tool of claim 15 ,

said frame including a base,

said frame including spaced apart first and second support members that extend from the base,

said handle extending from the base in a direction generally opposite the support members.

17. The tool of claim 16 ,

said first and second support members defining an elongated slot therebetween,

said slot extending along a slot axis,

said knife interface being aligned with and moving along the slot axis,

said base projecting radially relative to the slot axis beyond the support members.

18. A tool for steeling a knife, the tool comprising:

a frame,

said frame including first and second support members,

said support members defining an elongated knife-receiving slot;

a first steeling component and a second steeling component supported on the first and second support members, respectively,

said first and second steeling components being resiliently biased toward one another to define a knife interface configured to engage and thereby steel the knife,

said knife interface moving inwardly along a length of the knife-receiving slot to a terminal interface position, as the knife engages the interface and is shifted inwardly through the knife-receiving slot,

said knife-receiving slot having a maximum slot cross-sectional dimension defined between the support members,

at least one of said support members presenting an outer member portion extending along the knife-receiving slot outwardly relative to the terminal interface position,

said outer member portion having a maximum member cross-sectional dimension defined generally perpendicular to the length of the knife-receiving slot,

said maximum member cross-sectional dimension being less than about two times the maximum slot cross-sectional dimension,

said knife interface being located at a disengaged interface position spaced outwardly relative to the terminal interface position, prior to the knife engaging the interface,

each of said steeling components being shiftable between a first position, corresponding with the disengaged interface position, and a second position, corresponding with the terminal interface position, and

a stop stationary relative to the frame,

said stop engaging the first steeling component when in the first position and engaging the second steeling component when in the second position.

19. The tool of claim 18 ,

said maximum member cross-sectional dimension being no more than about ¾ inches,

said maximum slot cross-sectional dimension being no more than about ¾ inches.

20. The tool of claim 18 ,

said outer member portion of said at least one of the support members extending continuously between the terminal interface position to an outer end of the knife-receiving slot,

said outer member portion maintaining a constant shape along a length of the outer member portion.

21. The tool of claim 20 ,

said first support member and said second support member being substantially similar in shape.

22. The tool of claim 21 ,

said first support member and said second support member having an orthogonal shape.

23. The tool of claim 22 ,

said orthogonal shape being rectangular.

24. The tool of claim 18 ,

a second stop spaced from the first-mentioned stop,

said second stop being stationary relative to the frame,

said second stop engaging the first steeling component when in the second position and engaging the second steeling component when in the first position.

25. The tool of claim 24 ,

each of said stops being fixed relative to a corresponding one of the support members.

26. The tool of claim 24 ,

each stop presenting a first component-engaging surface configured to contact the first steeling component and a second component-engaging surface configured to contact the second steeling component,

said component-engaging surfaces being angled relative to one another.

27. The tool of claim 18 ,

said frame including a handle configured to be grasped by a user.

28. The tool of claim 27 ,

said frame including a base,

said first and second support members extending from the base,
