A knife is composed of a gripping handle and a blade adapted to be detachably mounted on the handle. The blade is formed with a profiled slot at a base portion to be secured to the handle. The handle has a blade mounting portion which comprises a supporting surface formed at one end portion of the handle for receiving the blade thereon, a stud projecting from the supporting surface and adapted to be inserted through the slot, a first stopper formed on the supporting surface at such a position that a portion of the back of the blade placed on the supporting surface with the slot having the stud extending therethrough can bear against the first stopper, a second stopper formed on the supporting surface at a position spaced from the first stopper so that another portion of the back of the blade placed on the supporting surface can bear against the second stopper, and a latch plate fixedly mounted on the free end of the stud and having a profiled contour such that the latch plate can pass through the slot at a predetermined angular position of the blade relative to the handle and prevent the blade from slipping off from the stud at the position in which the blade is held fixedly by the first and second stoppers in cooperation with the stud.
