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.

A knife includes a body that includes a handle section, a substantially circular blade housing section, and a blade including a cutting edge having substantially the same radius of curvature of the blade housing. The substantially circular blade housing section extends substantially perpendicular from the handle section. The blade extends longitudinally out of the blade housing at a position substantially 180° away from the position of the handle section along the circumference of the blade housing and terminates in a sharp point. The width of the blade at the portion immediately adjacent to the blade housing and opposite the blade point is substantially equal to the diameter of the blade housing.

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 novel cutting device useful for cutting asphalt shingles and other roofing products features a blade having a top edge, a bottom edge located on an opposite side of the blade relative to the top edge, and left and right edges; a lower cutting edge adjacent the left or right edge; an upper sharpened edge positioned above the lower cutting edge and adjacent the same edge as the lower cutting edge, wherein the upper sharpened edge and the lower cutting edge are configured for cutting; at least one inner edge emanating from the bottom edge and angled towards the top edge, wherein the inner edge is tangent to the upper sharpened edge; and at least on fin or nodule disposed between the lower cutting edge and the upper sharpened edge, wherein the bottom edge is parallel to and shorter than the top edge.

The invention relates to a novel knife with fire igniting capabilities as part of the knife itself. More specifically, the present invention provides for both a knife, and fire starting capability in one piece, which are both crucial to outdoor survival and useful in general camping and hiking activities. The handle can be hollow to contain a small survival kit, and the grips can be wrapped in paracord for other multiple outdoor survival uses.
