The Kokusin utilizes Arch Carbon to achieve arrow speed and flight superior to traditional carbon fiber bows. It is the pinnacle of carbon fiber bows.
It features a curved structure similar to a bamboo bow, making it more resistant to bending than flat-structured bows and functioning as a stronger spring.
It is stiffer than conventional carbon bows, enabling sharper arrow flight, and is thought to perform comparably to traditional products even with a 10% reduction in draw weight.
This model is a variation of the standard Kokusin, featuring simulated nodes mimicking a bamboo bow and a bamboo-like finish, bringing it closer to the appearance of a bamboo bow.
To achieve the natural texture of bamboo, it is a craftsman's masterpiece finished with meticulous hand-painting, especially around the nodes.
When newly manufacturing a 4-sun draw length bow with a 21kg draw weight, we strive to achieve your desired draw weight as closely as possible. However, due to the use of natural materials, there is a possibility of slight variations in the final draw weight.
Therefore, we will manufacture with an acceptable range of -0.5kg to +1.5kg from your ordered draw weight. We appreciate your understanding in advance.
