Poeticising the history or origin of the object, as we can see in the example Teki-gakure ('Waiting for the enemy'), chashaku by Ueda Sōko made in the first year of the Genwa period (1615).
During the Battle of Kashii in the early stages of the Summer Campaign of the Siege of Osaka, though all other supporting forces had withdrawn, Sōko refused to withdraw his own troops and held ground waiting for the enemy to approach. As he waited, he discovered fine bamboo in a bamboo grove and carved two chashaku with his small sword. This pair of chashaku were named Teki-gakure ('Waiting for the enemy').
