This is the chopping board stand that I finished assembling the other day.
Although it is strong enough as it is, we will add more strength and durability to ensure long-term use.
Make a 5mm square hole about 35mm deep.
Wood nails (KOMISEN in Japanese) made from cherry blossoms.
These techniques are also one of the traditional Japanese construction methods.
Not only is it strong, but it looks great too!
