The present disclosure is directed to biodegradable cutlery, and more specifically to spoons, forks, and knives. The biodegradable cutlery includes a plurality of recesses disposed on the handle forming a rib to resist twisting and bending. An indentation may be disposed along a neck of the cutlery to enhance stability further.

The knife includes a handle portion attached to a blade with a tip at its distal end. The blade comprises four surfaces that converge to form a spine and opposing cutting edges with each surface having a concave segment, a first angled segment, a flat segment, and a second angled segment as the surface extends from the spine to the edge. Similarly, the tip includes four surfaces that converge and terminate at a point, with each surface comprising only an angled segment. Optionally, the knife includes a unique safety lanyard that has two attachment points on the handle such that a closed loop is adjustably formed around the user's hand when gripping the handle, which aids in withdrawing the knife, stabilizing the user's grip, and preventing the hand from sliding forward while in use. Optionally, the knife includes a thumb plate as an additional safeguard.

A system may include a blade die, a first clamping caul positioned on a first side of the blade die, and a second clamping caul positioned on a second side of the blade die. A molding surface of the blade die and a molding surface of the first clamping caul may be configured to bend a first interchangeable blade positioned therebetween into a first shape in response to a first compression force. A second molding surface of the blade die and a molding surface of the second clamping caul may be configured to bend a second interchangeable blade positioned therebetween into a second shape in response to a second compression force.

A cutting implement includes a blade body including a base portion and a blade edge portion disposed along an end portion of the base portion. The base portion is made of a hollow body formed by sintering a first constituent material powder. The blade edge portion is made of a solid body formed by sintering a second constituent material powder. A reinforcing wall is provided inside the hollow body at at least a cutting implement tip portion of the base portion.

A method for forming a cutting tool includes masking a metal base with one or more masks, the one or more masks including at least one variable permeability mask, and chemically etching the masked metal base to form a blade of the cutting tool.
