Wakizashi shares the same blade as our Yamakami Wakizashi. Both
swords uses the Cheness SGC blade design and is especially made
for goza (tatami omote) cutting exercises.
The photos below
shows the overall appearance of the blade in and out of the saya.
This is a significantly broader sword with a narrower entry angle
in its cutting edge.
Due to the nature
of the geometry, the blade exhibits a hint of a pattern of how the
quench affected different parts of the blade differently than the
normal katana even though this is a through hardened blade.
uses a black cotton ito wrapping with a blackened steel tsuba and
an image of rabbits under a crescent moon. The steel used on this
blade is the through hardened version of the Cheness 9260 Spring
The handle of
this blade is slightly bigger than that of a standard katana. This
is to compensate for the broader blade and nakago within the handle.
of Cheness SGC Series Katana and Standard Katana
photos below are comparison of the Cheness SGC Series blade
and a standard katana. The SGC blades are thinner but broader
than the standard blade for purposes of improving its cutting
lateral strength of the SGC is just as strong if not stronger,
even though it is thinner, because of the additional material
in the height, providing support. Overall, the weight of
the blades on the SGC is heavier, but well distributed and
its center of gravity does not change from that of a standard
katana at 6" above the tsuba.
components on the SGC had to be re-cast... Including new
machined mold for the fuchi, kashira, habaki, etc. The Saya
is also significantly more substantial.
purpose of changing the blade cross-section geometry in
making the SGC is to significantly reduce the entry angle
of the cutting edge without reducing weight or lateral strength
of the blade.
in the diagram below, this change makes the SGC significantly
better at cutting. It is especially well suited for exercises
in cutting of goza mats or tatami omote. This blade also
handles bamboo extremely well.
of the Cheness 9260 Spring Steel employed in these blades,
the cutting edge holds up to the rigors of cutting exercises
where other steels would crumple or roll edge under this
overall geometry of the SGC katana is somewhat similar to
the Korean style Gumdo blades but still with significant
of this new design is based off of a $5,000 custom wakizashi blade
made especially for cutting exercises for some high ranking iaito
It took more
than half a year in planning, preparation, re-casting, machining
of new molds to bring this blade into a production basis and effectively
dropping the price down to less than a tenth of what it would have,
otherwise, cost to produce a similar blade in the past.
