A single bladed cooking knife having two cutting edges comprising:

• an enclosure for said knife including an upper half-shell and a lower half-shell joined to each other;
• means coupling one end of said knife to said enclosure for pivoting said knife from a first position within said enclosure with one of said cutting edges being positioned within said enclosure and another of said cutting edges positioned external of said enclosure to a second position with both of said cutting edges external of said enclosure;
• means for locking said knife in said first and said second positions;
• and
• means for releasing said locking means to move said knife from said first position to said second position and vice-versa, said releasing means including a lever pivotable about a joint coupled with said upper half shell, one end of said lever being associated with said locking means and the other end of said lever including means to move said lever to pivot said lever about said joint to move said one end for disengagement of said locking means.

A cooking knife including a cutting blade having two edged parts with only a single cutting edge comprising:

• a plastic oblong hollow shell haft formed by an upper half-shell and a lower half-shell joined with a weld line joining said upper half-shell and said lower half-shell;
• a blade provided in said shell haft and articulated on a pin joint passing through a hole provided at one end of said blade, said blade being manually movable by hand for engagement with one of two spaced ends;
• said two spaced ends including a front end and a rear end spaced from each other and formed at ends of a slot provided in said lower half-shell to provide for two positions for said blade;
• said manual moving of said blade to bring it into said positions, on said front end with said cutting edge totally exposing a straight saw-toothed edged part and, a half-moon shaped cutting part forming said two-edged parts and, on said back end with said cutting edge of the blade in a partial re-entry into said shell haft, only said half-moon cutting part shaped being exposed and having an inside edged part to complete the blade having said half-moon shaped part forming the saw-toothed edged part which is contained within said shell haft;
• means for locking the blade in a position on each of the spaced ends by fitting up of a constraint means including an iron leaf spring supported on one end between the half-shells and on the other end by a hook and lever arrangement, said lever being movable on a joint and associated with a push-button and said lever and hook being activated in response to said push button;
• engagement means on said leaf spring for engaging at least one rise, and removable therefrom in response to said push button for enabling said knife blade to be manually movable relative to said oblong shell;
• and
• said blade being manually movable from one end to the other end in response to activation of said push button for raising the leaf spring to permit one of said rises to be disengaged from the engagement means.
