Performance Ravenfall Kogarasu-maru Performance Katana | Black Ishime Lacquer Saya | Genuine Black Rayskin
Ravenfall (Kogarasu-maru) is a performance-grade Japanese sword forged in the rare Kogarasu-zukuri blade style, a transitional form that bridges the evolution from early straight chokutō to the fully curved tachi of later periods. Its defining characteristic is the double-edged kissaki, a distinctive feature that reflects both ancient lineage and refined martial design.
The blade is forged from high-toughness spring steel, offering excellent elasticity, impact resistance, and structural durability. This material allows the blade to absorb cutting stress effectively, making it well suited for repeated training and practical use. A precisely cut single bo-hi reduces forward weight, improves balance, and produces a clear, resonant tachikaze with each swing.
The shallow curvature and streamlined silhouette of the Kogarasu-maru provide smooth edge alignment and stable handling, delivering controlled, responsive performance ideal for tameshigiri (test cutting) and traditional Japanese martial arts practice.
The mounting follows a restrained, classical warrior aesthetic, allowing the rare blade geometry to remain the focal point. The tsuka is wrapped in brown ito over genuine black rayskin, offering a secure grip, excellent durability, and an understated visual contrast rooted in historical tradition.
The saya is finished in refined black Ishime (stone-textured) lacquer, evoking the quiet depth of falling night rain. Paired with a matching brown sageo, the overall presentation achieves a balanced harmony between historical character and modern craftsmanship.
Combining rare blade form, resilient spring-steel performance, and disciplined traditional mounting, Ravenfall (Kogarasu-maru) stands as an exceptional choice for practitioners and collectors seeking a sword that unites Heian-era heritage with dependable modern functionality.
