A knife adapted for competitive knife-throwing that includes removable guards that can be added in the case that the knife throwing is directed toward a target with holes therethrough. The removable guards can be put in place prior to throwing at such a target to provide a stop against the hazard of the knife potentially moving through a hole and hitting an unintended target.

A cold knife holder capable of pushing and pulling operations, includes a main body forming a chamber and a slot, a handle, a detent member, a first spring and a first steel ball. One side of the main body forms a perforation which communicates with the chamber. The handle includes a sleeve, a connecting rod and a grip rod. Both ends of the connecting rod are respectively connected to the sleeve and the grip rod, and the sleeve is pivotally sleeved on the main body, so that the handle is rotated relative to the main body, and the first or second caulking is connected to the perforation, and the detent member is arranged in the chamber. The first steel ball is pivotally embedded in the perforation, so that the detent member drives the first steel ball to be embedded in the first or second caulking, thereby positioning the handle.

Feather-indented knives and related methods. A feather-indented knife may be produced by a process that involves flat grinding a blade, creating texture and beveling with computerized numeric control (CNC) grinding, hardening the steel with a quench process heat treatment, and grinding the blade with CNC to produce a desired bevel thinness. The knife includes a plurality of lower and upper feather indentations that converge at a middle of the blade and point toward the handle of the knife. The feather indentations have a variable diameter depending on their position along the blade, and they enable sufficient air to enter the space between the blade and the food during a downward or rearward stroke of the knife to separate the food from the blade while cutting.
