Abstract
A method and device are provided to protect one's fingers from abrasion and paper cuts whenever forming a creasing line. The device consists of a pair of laterally-positioned elongated arms which are capable of providing a controllable creasing pressure at inwardly-facing opposed creasing surfaces. One of the arms is provided with a finger-gripping means to enable achieving a firm hold on the device during use as well as to prevent slippage of one's fingers from the device as it is moved while the crease is being formed. A stiletto-type letter opener and a sheet comber can also be provided with the device. The device can be made to stand upright on a desk for ready grasping in the identical position in which it will be used, and also has surfaces which are capable of carrying an advertising message or logo which are easily readable when the device is placed in such upright position.
