The Sigma Blade Zwei was a re-design of the original Sigma Blade, both signature models of Daisuke Shimada. Designed to be the "Ultimate Triple A" model, it featured YoYoJams composite body construction with weight rings meant to maximize weight distribution. A very tight design in a slimline concave, with super crisp metallic logos and stylized weight rings.
Pictured here is the third release in Black from March 2006. Of note, the first release featured Hybrid Response, but this third release included Double Yo-Ring Response.
