In the photos, the material of the object appears to have a certain "patina", that is not the case at all, it's raw bamboo and poorly planed. The scraper teeth are not all the same size and off-center (it obviously does not prevent scratching it right and especially without scratching) as the wheels (it looks like there are 3 x 2 but makes each wheel in each hole consists of 2 parts carved from the same piece of wood) whose axis is a little "nail", always bamboo (?), even more clearly, that does not seem very solid to me . What to see in use. Subject therefore very natural indeed ...
