What chashaku means
A chashaku is a long, curved bamboo spoon used to lift matcha out of the natsume or tin and into the chawan. Two level scoops hold roughly 1 gram, so usucha typically uses about four scoops and koicha about six to eight. It is a measuring and serving tool rather than a stirring tool.
