TK 36 - Detail (8).jpg [9/20] Title: Detail of Medical Instruments (VIII) - Thangka Thirty-Six Caption: The three instruments shown in this photograph are a hoe-shaped spoon, a broad saw and a specialized broad saw. These tools are classified under rigorous treatment since they are used for incision purposes. The black lines running next to the first and third instruments give a clear example of the measurement system for tools, which is based on finger-width units. In particular, the depiction of the third tool, the specialized broad saw, seems to vary greatly from set to set.
