Abstract
An interchangeable cutlery system has a blade handle incorporating a quick-change blade mechanism. A selected one of a plurality of blades can be removably attached to the handle via the mechanism. The plurality of blades include a filet knife blade, a back-serrated fillet knife blade, a clip point knife blade, a gut hook knife blade, a saw blade, a fish scaler, and a large bush craft blade.
Claims9
An interchangeable cutlery system comprising:
- a blade handle incorporating a quick-change blade mechanism, and
- a plurality of blades, each being removably attachable, in seriatum, to said handle via said mechanism,
- wherein said plurality of blades are selected from a group consisting of a filet knife blade, a back-serrated fillet knife blade, a clip point knife blade, a gut hook knife blade, a saw blade, a fish scaler, a bush craft blade, and multiple lengths of each version of said blades;
- wherein said mechanism comprises:
- a blade fitment plate, a first portion of said plate mounted in said handle and a second portion of said plate extending out of a distal end of said handle,
- a spring mounted to said first portion of said fitment plate and deflectable generally perpendicular to a plane defined by a longitudinal axis of said handle,
- a spring stud mounted on said spring,
- a release button mounted to said handle and operable to engage said spring, and
- an aperture in a proximal end of one of said blades, wherein said aperture is an elongated slot and wherein said second portion of said plate includes an elongated protuberance which is closely and slidably received in said elongated slot,
- wherein sliding said proximal end of said one of said blades into said handle while pressing said release button to deflect said spring permits said one of said blades to be inserted into said handle,
- whereupon releasing said release button once said aperture is aligned with said spring stud allows said spring to bias said spring stud into said aperture to attach said one of said blades to said handle, and
- wherein pressing said release button deflects said spring thereby moving said spring stud out of said aperture at which time said proximal end of said one of said blades can be slid out of said handle to thereby detach said one of said blades from said handle.

- wherein sliding said proximal end of said one of said blades into said handle deflects said spring by virtue of said one of said blades acting upon said spring stud, or pressing said release button deflects said spring, until such time as said aperture is aligned with said spring stud whereupon said spring biases said spring stud into said aperture to attach said one of said blades to said handle, and
- wherein pressing said release button deflects said spring thereby moving said spring stud out of said aperture at which time said proximal end of said one of said blades can be slid out of said handle to thereby detach said one of said blades from said handle.
