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 second release in Deep Blue from December of 2005. Of note, the first release featured Hybrid Response, but this second release included Double Yo-Ring Response.
