Cheness SGC Series (Specialized Goza Cutters)

These specialized blades were built based upon a custom designed sword created expressly for dojo cutting exercises. After more than half a year in planning and preparation, we have finally completed our SGC series for production... effectively bringing down the price of this sword from a $5,000 to $7,000 custom built range down to less than 1/10th of that cost.

These swords are broader and thinner than a standard katana. With a weight distribution optimized for cutting exercises. The entry angle of the cutting edge is effectively minimized by the geometry and is only made feasible with the Cheness Spring Steel, which aids in maintaining the edge durability.

The Tsukikage 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.

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 wakizashi even though this is a through hardened blade.

The Tsukikage 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 Steel.

The handle of this blade is slightly bigger than that of a standard wakizashi. This is to compensate for the broader blade and nakago within the handle.

The 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.

As illustrated 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.
