ABSTRACT:
A cutter is composed of a blade body and a stem. The blade body has an engage hole made up of a grip hole and a lock hole which is narrower than the grip hole and is extended to and connected with the grip hole. A peripheral portion of the lock hole defines a marginal portion. The stem has a blade body mounting section for supporting the blade body being put thereon. The blade body mounting section includes an engage projection adapted to be fitted in the engage hole of the blade body. The engage projection has a lock groove for receiving the marginal portion. The stem is provided with a push member adapted when controlled to push a first portion, on the side of the grip hole, of the blade body, whereby in response to the pushing action of the push member a second portion, substantially facing the grip hole, of the blade body is curved and separated from the engage projection.
