Tenryu means heavenly dragon and we see this koshirae as an evolution of our classic Genbu series Toryumon model. Like our other custom iaito, with the Tenryu Koshirae you have a wide array of choice over the design and aesthetics of your iaito. Though not fully customisable, it features many expanded options compared to standard set themed koshirae.The sand-cast bubble-free zinc/aluminum alloy blade is available up to 2.70 shaku. You can chose between Hyojun (normal, up to 2.45 shaku), Keiryo Toshin (extra-light, up to 2.45 shaku) or Habahiro (extra-wide) blade types. The Tenryu offers cotton sageo and tsuka wrappings in a color of your choice over white or black stingray skin.
