Product Description

Size 39 only.

This is a specially treated shinai, in which much of the water in the cellular spaces of the madake bamboo has been displaced, and replaced with a hard resin. Therefore the shinai is much less susceptible to changes in humidity.

This shinai is especially well-suited to dry environments which normally render un-treated shinai brittle and easily broken.

Built with premium quality tsuka-gawa, the handle portion, and all leather fittings according to current IKF rules.

Very sturdy, these are a premium shinai, the strongest bamboo shinai available, recommended for heavy practice schedules.

Plastic tsuba and elastic tsuba-dome included.

 

Dobari/koto types available.

A dobari-type shinai, with a fat mid-section, the center of gravity is back toward the middle-portion and tsuka, giving the shinai a very light tip.

Very sturdy, these are a premium shinai, the strongest bamboo shinai available, recommended for dry climates, and heavy practice schedules.

A koto-type, or "old-sword" shinai, the this shinai has a more straight, cylindrical shape than dobari, or conventional shinai.  It is of the style of shinai first used in kendo.

 

What Does "Bio Shinai" Mean?

The Bio shinai is a bamboo shinai in which the bamboo staves have been slow cooked in resin. This process causes the resin to replace the water in the cellular spaces of the bamboo. Upon solidifying, it produces a shinai that is much less suseptable to dry climates, or changes in humidity.

This shinai is highly recommended for dry climates, such as regions far from the ocean, mountainous regions, and anywhere where snow falls.

The shinai are shaped and crafted in such a way as to comply to minimum weight specifications mandated by the All Japan and International Kendo Federations. However, they may vary from ten to 20 grams over the minimum weight specifications.  

Please keep in mind: the four component pieces for a single shinai that are taken from one pice of bamboo, must be matched to provide for the ideal shinai in which the "fushi," the nodes, or "knots," of the bamboo are matched exactly. Therfore during the extensive process of treating the individual pieces, the ha, or slats, which are then finished, careful attention to tracking, and re-assembling the matched-pieces must be done without error.

Our Bio shinai are shaped, sanded, and polished before shipping, resulting in a beautiful shinai. Fitted with premium heavyweigth tsukagawa, the leather handle, and other leather fittings to comply with the All-Japan and International Kendo Federations Rules, we also include a plastic tsuba and tsuba-dome, for a complete shinai, ready to use upon receipt.

Tsukagawa, the leather handle: If you include any special instructions in the comment-section of the final order page, we can equip your shinai with tsukagawa length to your specifications. Standard tsukagawa are catagorized by the shinai length, for example: a 3-9 tsukagawa for a 39 shinai, and so forth. If you have any questions, please contact us.

We recommend that the shinai be wipped down with a moist cloth occasionally, (not a wet tenegui, or face-towel, due to sweaty salt content,) and that soaps and detergents also be avoided, in the care and maintenance of the Bio shinai.

The particular Bio shinai that Chiba Budougu, Ltd. has selected are the two premium models of the Bio line. The treatment of the bamboo is most effective on high quality bamboo, the bamboo with the best properties for use in shinai.

Also, other versions of the two types we offer, the koto and dobari styles, in which the bevel-angle of the edges of the ha, or slats are cut at a lower angle, resulting in a shinai with a narrower striking surface, the portion of outer-skin of the bamboo, are also available; however, these shinai, although being slightly lighter than the models we offer, are incrementally weaker.

As Bio shinai users select these shinai for their long-life and durability, we have chosen the models that offer best cost-and-performance. Less expensive models of the Bio line which employ lesser grades of bamboo are also manufactured, so please keep this in mind when looking at other sources.

Although the Bio shinai is more durable than a bamboo shinai in the hands of a skillful kendo practitioner, it is still in fact a bamboo-based object and may break: Due to its role as a striking instrument, neither Chiba Budougu, Ltd., nor the manufacuters of the Bio shinai can be held liable for any failure of the shinai, or personal injury resulting from use of these shinai.
