Attractive Signed Eiroku Era (16th Century) Japanese Tanto Length Knife Blade with NTHK Certification

Measuring 16 inches overall with an 11 1/2 inch live edge, the blade features a strong, slightly wavy hamon, attractive and vivid grain, and a 3 inch long horimono on each side depicting a bald man wearing a head dress. A silver plated habaki is present, decorated with slanted serrations. The tang has two mekugi-ana and is engraved on both side. The furniture is of the shirasaya pattern, with ebony and bone trim/reinforcement. A set of paperwork from the NTHK (both the fine "origami" presentation paperwork and the examiner's worksheet, with numbered envelope) is included, identifying the left side marking as the signature "Bizen Kuni ju Osafune Kiyomitsu" (a smith of the Bizen school, active from 1558 to 1570), and the right side marking as the date "Eiroku 3 Nen 8 Gatsu Hi" (3rd year and 8th month of the Eiroku era, approximately 1561). The blade was rated at 70 points, qualifying for "Kantei Sho" (authentic) level certification.

ConditionThe fine blade shows some mild spotting, light handling marks and a few openings in the skin but is bright with a well defined hamon. The tang shows a darkened patina appropriate to the documented age. Mekugi is absent. The furniture is good, with mild stains, wear, and some cracking of the trim.
