A manipulator of a compass for drawing a circle or a compass-cutter for cutting an object in circular configuration is provided with a mechanism for transmitting the force from the user's hand only in one direction. With such the construction, a user can smoothly draw a complete circle at 360 degree, or can cut a paper, a cloth and so on in circular configuration, without re-pinching the manipulator during operation, in a manner for a ratchet which is a commercially available tool.
