Use this tool to score and break a variety of sheet materials including decorative laminate, vinyl sheet, tile, Plexiglas, drywall, and many others.  Especially useful when very long cuts must be made.  Also useful on the job when available tools are limited and when there is no power.  Use a straight edge as a guide, make several scores, then bend upward toward the decorative side for laminate, downward for most other materials.  Also popular for removing grout from between ceramic tiles in preparation for re grouting.  The reversible blade has a carbide tip on each end for double life.
