The pattern of ya-bane, or "feathered arrow," carved into the cutlery is a symbol of the courage to face new challenges, protection against evil, and the samurai spirit of Kamakura. 

​

Samurai warriors who achieved the revolution to establish the new era from the world of aristocracy in Kyoto to the samurai warriors of Kamakura used the bow and arrow not only as weapons but also as sacred objects to deliver prayers to the gods as we still see in yabusame, Japanese equestrian archery today.
