Abstract
A sheath consists of an elongated member with an internal volume designed to securely and removably receive the end of an elongated cylindrical instrument with a suitable radius, such as a pen or pencil. The sheath can be comprised of an elastomeric material which allows the sheath to expand as the cylindrical instrument is inserted into the internal volume, and thus exert a radial force upon the instrument and restrain any motion of the instrument relative to the sheath. The elastomeric material has a lesser hardness than the screen material so that it will not damage the screen, but a greater hardness than a soft pencil eraser so that it overcomes the problems associated therewith. The sheath can be made with a tip of any shape and sharpness so that it will be compatible with any touch-sensitive screen.
