Abstract
A sawblade and a drive spline having a drive configuration therebetween. The drive configuration comprises inner driven surfaces on the sawblade which are driven by the drive spline which has outer drive recesses complementary to the inner driven surfaces of the sawblade. First and second radials extend outwardly from the axis of rotation of the drive spline and sawblade. They extend so as to contact the ends of a respective recess or drive surface most closely located to the axis of rotation. Second and third radials extend to contact the ends of the most remotely located recess or drive surface. The angular distance between the first and second radials is greater than the angular distance between the third and fourth radials.
