ABSTRACT:
A knife of which the blade is brought into or out of a haft by revolving against the haft, having a locking system fixing the blade to the haft in usable condition by a hand, is provided with a function that not only bringing the blade into or out of the haft but also the action and the release of the locking system can be done only by one hand. The operation knob 11 is attached to a part of the blade 9 where a thumb of a hand holding the haft 2 can operate the operation knob 11. The action and the release of the locking system are determined in accordance with a direction of the force added to the operation knob 11 toward the direction of the blade 9 being brought into or out of the haft 2. The operation knob 11 is added force by a thumb of a hand holding the haft 2 toward the direction of the blade 9 being brought into or out of the haft 2.
