ABSTRACT:
A knife having an elongated holder provided therein with a channel to the exterior at its upper side through a slot provided in the top wall of the holder, a blade carrier having a slider slidably received by the channel of the holder, and a blade detachably secured to the blade carrier through an engagement between a projection formed on the front end portion of the slider and an aperture formed in the base portion of the blade. The knife further has a spring or the like for resiliently biasing the front end portion of the slider to bring the projection into engagement with the cooperating aperture in the blade, and a manually depressable finger portion for causing a downward movement of the front end portion of the slider to disengage the projection from the aperture in the blade against the resilient biasing force. The finger portion, which is integral with the slider through the slot, has a width greater than that of the slot, so that the finger portion cannot be depressed normally. A transverse enlargement of the slot in the top wall of the holder is adapted to receive the front end portion of the finger portion to permit the depression of the latter, thereby to disengage the projection of the slider from the aperture of the blade, only when the blade carrier has been slid to a predetermined position in the channel.
