星形針亦稱“棱形針”，將其工作段設計成等邊四角形，這就可以在兩個鋭角上製造鈎刺，它除了具有鑚石形針的特?外，還增加了針刺效率。 Also called “l(fā)ozebge” needles with the working part designed as a four equal-side quadrangle. Thus barbs can be manufactured on two sharp angles. In addition to all the shared characteristics of the diamond needles, the star needle increases effective ratio of the needle punch.
