The remarkable aspect of 'ichi-i-ittoō-bori' lies in their refusal to apply color, instead highlighting the inherent beauty of the wood grain itself. They skillfully utilize the contrasting hues of heartwood and sapwood, along with the chisel marks. Furthermore, they employ precious wood from yew trees aged 400 to 500 years. Their dynamic, powerful expressiveness, integrated with the wood grain, and the luster that deepens over time are also captivating.
