ABSTRACT:
A utility cutter includes a cutter blade, a cutter handle, a blade frame, and a blade replacement arrangement. The blade frame includes a first and a second frame member pivotally mounted with each other to define a blade receiving cavity that the cutter blade is substantially retained at the blade receiving cavity, wherein the blade frame is pivotally mounted to the elongated cutter handle for folding between a folded position and an unfolded position. The blade replacement arrangement is operatively coupled with the first and the second frame member for normally locking the first and the second frame member with each other. When the blade frame is in the unfolded position, the blade replacement arrangement is adapted to unlock the first frame member, such that the cutter blade is capable of being conveniently and safely replaced at the blade receiving cavity without sliding movement of the cutter blade.
