Shima Kokutan Deluxe Tanto Made in Japan (Kyushu) Flat Spine | Rounded butt | Short Kissaki Deluxe Tanto made out of a single piece of Shima Kokutan (Asian Ebony). The shape and length are resolutely classic, making it a standard tanto that will be appreciated by all aikidoka. Please note that Shima Kokutan is a very hard wood; it absorbs shocks relatively poorly and is not advised for practice with contact. Finish: Unvarnished (camelia oil-polished) Manufacturing workshop: Aramaki All our high-end weapons are offered unvarnished (camellia oil polish finish). Note that unvarnished weapons are much more pleasant to the touch as well as usage.Unvarnished weapons are more ecologically-friendly, but they require regular (monthly) maintenance with oil (camellia or wood maintenance oil) and they can only be made from the finest woods. Given the need for maintenance of these weapons, our stocks are limited. Also, since the craftsmen must select the best wood possible to manufacture these weapons, the processing time is longer than for varnished weapons Please note that due to the rarity of the wood and the limited release of this product, engravings are not available.
