Making
the Blowing Edge and Inserting the Utaguchi
 |
Cutting the blowing edge of
the shakuhachi at the appropriate angle. A bamboo saw with very
fine kerf is used in this process. Traditional tools for making
shakuhachi are becoming increasingly difficult to find as the
younger generations fail to take on apprenticeship in the craft. |
 |
The utaguchi (which
translates from Japanese as "song mouth") is marked
on the blowing edge surface and cut with a small, high-speed
circular saw. This is my own technique which results in a very
accurate fit. |
 |
The corners of the
utaguchi cut are carefully finished with a fine hand saw and
needle files. The utaguchi shown in these photos is traditionally
used by the Kinko Ryu. Tozan and Meian Ryu use a curved utaguchi
which is more difficult to insert. |
 |
The utaguchi itself
is fashioned from a piece of water buffalo horn or, more commonly,
from acrylic and carefully shaped to match the angles of the
cut placed in the bamboo. A fine strip of silver or gold is often
wrapped around the utaguchi to provide a highlighted border in
the finished piece. |
 |
Once the utaguchi
is inserted, glued and cut, the curvature of the blowing edge
is reshaped to precise dimensions. The depth and degree of curvature
is critical to the performance of the instrument. |
