Blade Features:

The blade is crafted in the traditional shinogi-zukuri style, characterized by a prominent ridge line (shinogi) running along its length. It exhibits a saki-zori curvature, which is more pronounced near the tip, adding to the blade's elegance. The chu-kissaki (medium-sized tip) complements the overall design, while the iori-mune (roof-shaped back) enhances the blade's structural integrity. The gentle oroshi (gentle slope) and the low-positioned shinogi further define the blade's aesthetic and functional attributes. The hamon is an exquisite ko-choji-ba, featuring a series of small, clove-like patterns that exemplify the exceptional craftsmanship of the period.
