Bar scriber is a handy tool for precision marking and cutting of all types of vinyl flooring. A scriber hand tool used for marking lines on your flooring, prior to cutting. Use a scriber instead of pencils as the marks from pencils cannot be seen as clearly as scriber marks. Made of steel that has been sharpened to a point at one or both ends. They are used by drawing the point over the surface of the vinyl to leave a shallow scratch on its surface. Due to the nature of metal, and the accuracy generally sought after when cutting vinyl flooring, a thick pencil or ink line would either be impossible to lay down accurately or prone to erasing.
