A rotary knife apparatus has first and second protecting strips placed on both sides of a joint end of a blade of the rotary knife, and two protecting strips placed on the same base tube as a rotating point. A bi-fork braking component is used to control its opening. A toggle control component is placed on one end of the bi-fork braking component that faces the direction of a grip, and the end faces a joint end has a first and second acting fork.
