- a blade having an exposed blade end portion and a handle attachable unexposed end portion;
- a cutout in said handle attachable unexposed end portion of said blade;
- at least one locking groove placed around said cutout in said handle attachable unexposed end portion of said blade;
- a spring bias lock mechanism located in said cutout in said handle attachable unexposed end portion of said blade;
- wherein said spring bias lock mechanism comprises a spring and a moveable component so that said moveable component is engaged in said at least one locking groove to provide a secured blade position on said handle;
- a disk capable of housing said spring bias lock mechanism, wherein said disk is attached to said handle and located in said cutout;
- an unlock mechanism having an attachment connected to said moveable component to disengage said moveable component from said locking groove;
