The STANLEY® INTERLOCKING® Retractable 18mm Snap-Off Utility Knife
features 1 blade with 8 cutting segments for a longer life span and an
interlocking nose design for improved safety, securing the blade firmly
in place and preventing nose spread and body separation that might
otherwise cause blades to break-loose and cause injury. Its tough and
solvent resistant die-cast metal body and blade wheel lock is ideal for
heavy duty cutting, and its multi-position retractable blade for
versatility, control and safety, makes it suitable for all types of
professionals and home improvement jobs.
