ABSTRACT:
A replaceable blade type knife in which the blade is replaced at an intermediate point between opposite longitudinal ends of the case body so as to improve the operational efficiency and safety of the knife. The knife includes a restrictive arrangement for enabling dismounting of the sliding member from the guide grooves of the case body at a specific position within the guide stroke of the sliding member other than at the opposite ends of the guide stroke and for unreleasably restricting the sliding member in the guide grooves of the case body at positions other than the specific position so as to allow the sliding member to slide in the guide grooves of the case body, and thus, the knife has been made compact in size so as to be suitable for portable use, with a wide range of application to office works, handicraft, etc.
