ABSTRACT:
A felting needle having a wedge-like tip with an open double barb formed in the leading edge of the tip. The double barb includes a pair of opposed outwardly diverging fiber-engaging surfaces with precisely formed angles. One outwardly diverging barb angle extends to one side of the needle, and the other outwardly diverging barb angle is disposed symmetrically and diametrically opposite thereto. Unlike ordinary barbs formed in a lateral edge of a felting needle, the double-barb of the present invention allows fibers to slip off to either side of the needle and thus prevent fiber damage.
