This pottery turning hook is a manual tool with a right angle blade (approx. 2 cm by 0.5-1 cm) that can take different shapes: rectangular with or without rounded corners, triangular, etc. It can be made entirely of metal or have a wooden handle .
There may also be a spatula-shaped blade at the other end.
The turning tool is used by the potter to update the shape of a turned pot while turning. If it is held against the pot, a certain amount of clay is cut off. [MOT]
