A plaster cutter, also known as a cast saw, is a power tool used to remove orthopedic casts.
It's blade is designed to cut through hard materials like plaster or fibreglass without damaging soft tissues like skin.
It is made of a hard, long-lasting metal, such as tungsten carbide.
It has a sharp, narrow-toothed blade that rapidly oscillates or vibrates back and forth over a very small angle to cut the material.
When the blade makes contact with the cast, it vibrates at a high frequency, causing the cast to shatter.
