This instrument offers an easy method for the determination of film hardness for coating applied to a flat substrate. The pencil lead, prepared beforehand by rubbing it on fine abrasive paper (400), is maintained at an angle of 45º and pushed with uniform pressure onto the sample, either leaving a superficial trace or causing destruction down to the substrate.
