Abstract: A folding knife includes a handle and a blade, rotatably connected to the handle with an axial shaft. The handle has two or more parts, together the parts of the handle form a cavity in which the blade is placed in the closed position. The blade has a working sharpened edge and a shank, and rotates about the axial shaft from the closed position, in which the working sharpened edge of the blade is positioned within the cavity, to the open position, in which the working sharpened edge of the blade protrudes from the handle and allows the cutter to be used. One of the parts of the handle includes an additional recess containing a zigzag spring and a hook. One end of the spring is connected to the handle, and its other end is connected to the hook. The hook is pivotally connected to the blade of the knife and transmits to it the force of the stretched spring, which allows the knife to open under the force of compression of the spring. The shape of the hook is such that it partially encircles the axis of the knife, and the place where the hook is connected to the blade is such that the folded knife does not open under the influence of the spring until the user withdraws the blade from the folded position to a certain angle, thereby initiating further opening of the knife under the influence of the spring.

Abstract: A folding knife, including a handle, with at least two parts connected to form a cavity therebetween, and a blade having a sharpened edge and a tang. The blade is rotatable between an open position and a closed position. The blade defines a first plane inside the cavity. The tang includes a step protrusion and a rounded protrusion. A stop pin restricts movement of the blade in an opening direction. The folding knife also includes a locking member rotatable from a first position, allowing the blade to rotate, to a second position blocking rotation of the blade by engaging one of the tang's protrusions. The engagement of the locking member with the step protrusion of the tang locks the blade in its open position, and the engagement of the locking member with the rounded protrusion of the tang locks the blade in its closed position.

Abstract: A knife having a blade and a handle. The blade includes at least one cutting edge, a tip and a base. The handle includes a connection mechanism connecting the base of the blade to the handle. The cutting edge of the blade includes a plurality of serrated groups, each serrated group having at least a first arched recess with a first dimension, a second arched recess with a second dimension, and a third arched recess with a third dimension. The second dimension is at least 30% greater than the first dimension, and the third dimension is at least 30% greater than the second dimension. The arched recesses of each serrated group are arranged in ascending order in a direction from the tip of the blade to the handle. Multiple serrated teeth are formed between adjacent arched recesses.
