At present, most of the shakuhachi are made of bamboo tubes, and a good high-grade bamboo shakuhachi can be as little as several thousand, and it can be tens of thousands. It is not uncommon for bamboo to crack due to stress shrinkage due to careless maintenance in the dry seasons of autumn and winter.
Of course, cracked bamboo shakuhachi can also be repaired by yourself or by a professional. It's just... the feeling of being gone forever is only understood by myself.
It is better to plan ahead than to make amends. In fact, the bamboo shakuhachi is most afraid of drying and cracking. In autumn and winter, the air is dry, and the water in the bamboo shakuhachi evaporates completely, causing the shakuhachi to crack.
Shakuhachi can be stored in a sealed bag. When playing the shakuhachi, the shakuhachi is actually hydrating. The breath exhaled by the human body and the contact of the shakuhachi forehead of the human body will transfer the water to the shakuhachi. The inner diameter of the shakuhachi wiped off the water in the inner chamber of the shakuhachi, and then put the shakuhachi in a sealed plastic bag.
Rubbing oil, usually about once every two weeks, apply vegetable oil on the bamboo surface, which can produce moisturizing effect and reduce the possibility of cracking. Apply a small amount and wipe off. The purpose is to form a thin oil film on the bamboo surface to prevent water from evaporating. The oils used are all plant-based like bamboo, and it is best to use natural camellia oil, olive oil, walnut oil, etc.
