Upgraded Tsuka Core
All of our full
length and extended length katanas now uses the upgraded tsuka core.
The core consists
of a new higher grade hard wood with higher density
for improved durability. The finish is more refined and tapered
at the end. On each side of the core, there is a carved, grooved
channel allowing for the panel wrap same skin to sit flush
to the tuska. What this accomplishes is to allow for the cotton
ito wrapping to flow more smoothly over the surface of the handle,
which in turn, allows for a tighter wrapping.
the new tsuka feels more oval to the grip allowing for the
directionality of the blade to be felt... but not so much
that it would hurt your palm over extended use.
the tightness of the ito wrapping, the top and bottom surfaces of
the tsuka is added with a layer of non-permanent rubbery adhesive
to add traction to the ito so that the wrap would not slip from
the core... even if the ito should lose tightness over time.
new tsuka are fitted onto the nakago with two off-set mekugi pins
entering from the opposite sides of the tsuka. The mekugi pins have
also been updated by using only seasonally harvested (winter) bamboo
that has been thoroughly cured. (We stockpile our mekugi bamboo
over winter time so that we won't have to use the summer harvested
bamboo which has several significant problems).
