Abstract
A cutting pen with a bar-shaped cutter having a blade portion at one end thereof and a cylindrical holder into which the bar-shaped cutter can be inserted from the other end of the bar-shaped cutter. The holder has a radial bearing disposed corresponding to one end of the bar-shaped cutter and a thrust bearing disposed corresponding to the other end to support the inserted bar-shaped cutter in such a manner as to allow rotation around the axis thereof. The cylindrical holder attracts and holds therein the bar-shaped cutter by magnetic attraction, in such a manner that the work of attaching and/or detaching the bar-shaped cutter can be performed simply and easily in a short time, and the bar-shaped cutter is held firmly preventing it from falling off the cylindrical holder during use of the cutting pen.
