Name of the tool to decorate pots in Bih language (Buôn Trấp)

H’Loan Bkrong and H’Lân Êban say the name of the tools used to decorate pottery. Two different tools can be used: a simple bamboo stick with a pointed end and a tool that I have not seen during my visits, but that LTS has seen on her previous visits to the village. It is a stick with one end shaped like a small fork that allows the potters to make three lines at the same time. Both have the same name
