ABSTRACT:
The invention relates to a blade for an indoor bandy stick, comprising a top-edge reinforcing rib (5), a bottom-edge reinforcing rib (6) and therebetween a number of reinforcing ribs (7, 9) which lie lengthwise of the blade and are spaced from each other so as to form open spaces between the lengthwise ribs (5, 6, 7, 9). The interspace between the mid-section reinforcing ribs (7) is located at the distance of a radius (D/2) of a ball (3) from the bottom edge of a blade (12). Thus, the ball hits the reinforcing ribs at more than one point along the ball surface. One or both sides of the blade can be concave.
