A skinning knife includes a handle, a blade carrier coupled to the handle, the blade carrier including a mount having a mounting surface, a boss extending outward from the mounting surface, and a spring including a front portion, a middle portion, and a rear portion, the front portion secured to the mount, the middle portion bent outward from the front portion and the rear portion, and the rear portion including a free end of the spring movable relative to the mount, and a blade including a sharpened edge, a body, a slot formed through the body, and the slot includes a narrow portion and a wide portion, The blade is releasably secured to the blade carrier by interaction between the boss and the spring of the blade carrier and the slot of the blade.

First claim

What is claimed is:

1. A skinning knife, comprising:
a handle;
a blade carrier coupled to the handle, the blade carrier including a mount having a mounting surface, a boss extending outward from the mounting surface, and a spring including a front portion, a middle portion, and a rear portion, the front portion secured to the mount proximate a front end of the spring, the middle portion bent outward from the front portion and the rear portion, and the rear portion including a free end of the spring movable relative to the mount;
a button coupled to the rear portion of the spring and configured for actuation by a user to move the rear end of the spring; and
a blade including a sharpened edge, a body, and a slot formed through the body, the slot extends in a longitudinal direction from a front end to a rear end and includes a narrow portion of a first width and a wide portion of a second width greater than the first width, the narrow portion includes the front end of the slot and the wide portion includes the rear end of the slot;
wherein, in a first mode of operation, the blade is secured to the blade carrier with the boss positioned in the narrow portion of the slot and the engaging the front end of the slot and the middle portion of the spring positioned in the wide portion of the slot and engaging the rear end of the slot; and
wherein, in a second mode of operation, the blade is removed from the blade carrier by depressing the button so that the middle portion of the spring is moved out of engagement with the rear end of the slot and allowing the boss to be moved out of engagement with the front end of the slot.

2. The skinning knife of claim 1 , wherein the middle portion of the spring includes a first leg and a second leg, with the first leg bent at a first angle relative to the front portion of the spring and the second leg bent at a second angle relative to the rear portion of the spring.

3. The skinning knife of claim 2 , wherein the first angle is less than the second angle.

4. The skinning knife of claim 3 , wherein the mount includes an aperture, and wherein the middle portion of the spring is positioned within the aperture.

5. The skinning knife of claim 4 , wherein the blade includes a top edge and a bottom portion of the cutting edge, the top edge is spaced apart from a top of the slot by a first distance and the bottom portion of the cutting edge is spaced apart from a bottom of the slot by a second distance greater than the first distance;
wherein the button includes a bottom edge spaced apart from a top edge of the spring by a third distance less than the second distance so that the blade can only be secured to the mount with the top edge of the blade adjacent the bottom edge of the button.

6. The skinning knife of claim 1 , wherein the mount includes an aperture, and wherein the middle portion of the spring is positioned within the aperture.

7. The skinning knife of claim 6 , wherein the blade includes a top edge and a bottom portion of the cutting edge, the top edge is spaced apart from a top of the slot by a first distance and the bottom portion of the cutting edge is spaced apart from a bottom of the slot by a second distance greater than the first distance;
wherein the button includes a bottom edge spaced apart from a top edge of the spring by a third distance less than the second distance so that the blade can only be secured to the mount with the top edge of the blade adjacent the bottom edge of the button.

8. The skinning knife of claim 1 , wherein the blade includes a top edge and a bottom portion of the cutting edge, the top edge is spaced apart from a top of the slot by a first distance and the bottom portion of the cutting edge is spaced apart from a bottom of the slot by a second distance greater than the first distance;
wherein the button includes a bottom edge spaced apart from a top edge of the spring by a third distance less than the second distance so that the blade can only be secured to the mount with the top edge of the blade adjacent the bottom edge of the button.

9. The skinning knife of claim 1 , wherein the blade carrier is pivotally coupled to the handle.

10. The skinning knife of claim 1 , wherein the blade carrier is rigidly coupled to the handle.

11. The skinning knife of claim 1 , wherein the boss includes a narrow portion of a third width and a wide portion of a fourth width greater than the first width and the third width, the narrow portion positioned between the mounting surface and the wide portion; and
wherein, in the first mode of operation, the narrow portion of the boss is positioned in the narrow portion of the slot so that the wide portion of the boss overlaps a portion of the body of the blade adjacent the narrow portion of the slot.

12. The skinning knife of claim 11 , wherein the middle portion of the spring includes a first leg and a second leg, with the first leg bent at a first angle relative to the front portion of the spring and the second leg bent at a second angle relative to the rear portion of the spring.

13. The skinning knife of claim 12 , wherein the first angle is less than the second angle.

14. The skinning knife of claim 13 , wherein the blade includes a top edge and a bottom portion of the cutting edge, the top edge is spaced apart from a top of the slot by a first distance and the bottom portion of the cutting edge is spaced apart from a bottom of the slot by a second distance greater than the first distance;
wherein the button includes a bottom edge spaced apart from a top edge of the spring by a third distance less than the second distance so that the blade can only be secured to the mount with the top edge of the blade adjacent the bottom edge of the button.

15. The skinning knife of claim 1 , wherein the rear end of the slot is rounded.
