Knife and Sheath with Retention System

A knife and sheath system comprising:

• a. a knife comprising a handle, a blade comprising a first edge and a first end, wherein the first end of the blade attaches to the handle, and wherein a knife protrusion extends from the first edge of the knife near the first end;
• and
• b. a sheath comprising:
• i. a blade guard comprising a handle section attached to a perimeter section, wherein the handle section and perimeter section define a first knife pocket that receives the knife blade;
• ii. a sheath protrusion fixedly attached to the handle section of the blade guard and extending into the knife pocket, wherein the sheath protrusion is configured to cooperate with the knife protrusion;
• iii. a blade cover positioned within perimeter section of the blade guard;
• and
• iv. an action having first and second ends and a center section disposed between the first and second ends, wherein the action attaches to the blade cover at one of the action ends and wherein the center section of the action biases the blade cover toward the sheath protrusion.

• and
• b. a sheath comprising:
• i. a blade guard comprising opposing first and second sides and a handle section attached to a perimeter section, wherein the handle section and perimeter section define a first knife pocket that receives the knife blade, wherein the handle section further defines a fixed sheath protrusion that extends into the knife pocket, and wherein the sheath protrusion is configured to cooperate with the knife protrusion and knife first edge;
• ii. a blade cover comprising opposing first and second sides and a perimeter edge along a portion of the blade cover perimeter, wherein the blade cover is positioned within perimeter section of the blade guard, wherein the blade cover defines a second knife pocket configured to receive the knife blade, and wherein the blade cover further defines an action pocket along its perimeter edge and adjacent the knife second edge when the knife is seated in the second knife pocket;
• and
• iii. a resilient action having first and second ends and a center section disposed between the first and second ends, wherein the second end of the action is positioned in the action pocket of the blade cover and wherein the center section of the action biases the knife toward the sheath protrusion when the knife is seated in the second knife pocket.
