The standard cooking chopsticks for wooden chopsticks in Hokkaido are only walnuts. In the past, I used to make saibashi out of Enjyu wood, but even if the size is a little longer, there is a problem in continuing to use it as a standard product, so I have narrowed down the material to 1 types. The onco's Ainu Carving Chopsticks ", which is a product featured in this publication, is different from the standard product and also different from the practical product, it is like a commemorative chopstick with an Ainu carving in the Showa period. It is not colored, so it has a different color of Onco. Along with Erimaki Saihashi, they are rare Ainu pattern carved chopsticks made of Onco wood.
