In year 1992, YONEX developed the world's first epoch-making technology in badminton ...the ISOMETRIC Square Head Shape. This YONEX development continues to sets the pace of winning play. The Isometric Square Head Shape badminton racket design provides a 32 percent larger effective hitting area than a conventional oval shape badminton racket. Also, unlike a conventional badminton racket with main and cross strings of varying length, the Isometric Square Head Shape equalizes the length of main cross strings in the string-bed enlarging the sweet-spot all around for more consistent shot accuracy, even on off-center hits.
