A Naotane ‘3-Body Cutting Test’ Katana

We cannot highlight every sword in the catalog here, but we showing you an example of a rare and valuable sword, photo above. This sword is signed and dated from the Shinshinto period – Bunka era: October 6th 1815.  This katana was commissioned by a samurai from the swordsmith grandmaster Taikei Naotane. This museum-worthy jûyô tôken blade has performed an ultra-rare 3-body cutting test – see below. This appears to be the only jûyô token cutting test piece in existence that can make this claim.

The swordsmith Taikei Naotane used his student Shigetane to test the sword’s sharpness and strength, by cutting through a human body, known as tameshigiri. This method was as close to reality as possible and usually they would use convicted criminals who have been sentenced to death (carried out prior to the test cutting). This katana was able to cut cleanly through three bodies, making it very rare indeed.

This blade performed a tameshigiri (cutting test) severing three human bodies in one stroke. This feat alone is rare and impressive. However, what makes this katana extra special is that the test was completed by Naotane’s master student, Sawara Shigetane – a swordsmith – not by a professional sword tester. And that it was commissioned by a Hatamoto-ranked samurai.

To give further perspective, of the circa 12,000 jûyô tôken certified swords, there are only about 130 swords with a tameshigiri cutting test. And of those 15 are anonymous, that is, they only record the cut that was performed and/or the number of bodies the blade cut through. Eight were carried out by non-professional sword testers, e.g., certain samurai retainers who were testing swords for their fiefs.
