  • Patent number: 5735622
    Abstract: An improved writing instrument and method for manufacture thereof wherein a coating of a varnish mixture including a hardening component is applied by spraying or dipping or being force fed through a lacquer pot and squeegee to coat the external housing of the writing instrument to provide it with a compressible polyurethane friction coating thereon which is soft to grasp to greatly facilitate grasping and holding thereof. The compressible friction coating is more compressible than the conventional plastic, wood or composite material normally used for the external housing of a writing instrument such as a pen or pencil and provides a high friction surface to facilitate grasping and aid in accurately writing or drawing as desired. The external housing can include one or two coatings of the compressible polyurethane friction coating such as to provide additional compressibility thereof.
