Is the Japanese wordless old firewood knife good?

Not so good. Japanese wooden knives with words will be better. The words on the Japanese wooden knife indicate the name of the sculptor, and a knife with a name will be better. Japanese Dao (にほんとぅ, Japanese head), a general term for Japanese traditional Dao by foreigners, is called flat-broken-section compound dark-light-textured Dao. According to the shape and size, it can be divided into broadsword, beating knife, poor threat (threat refers to) and short knife. Among them, the knife mentioned by the Japanese refers to the shape of the beating knife. Japanese knives in a broad sense also include long scrolls, knives, swords and guns.
