Specifically for allrounders, who desire a blade with a harder backhand, we have modified our model Spin Machine into the Spin Block. Considering the feedback of our affiliated players we have replaced the Koto veneer of the backhand with a harder nut tree veneer. Because of the harder veneer this model is a bit faster and heavier than the model Spin Machine, but with approximately 60g in the standard size and 70g as defense blade it is still very light!
