The Chisel Point
The Chisel Point is very different in appearance and performance as compared to any standard needle point. Pictured in Figure 11, the Chisel Point is produced by effectively slicing away the front tip of the needle, leaving a pointed end with a profile shaped exactly like that of a chisel. The main surface of a Chisel Point is a flat diagonal, rather than a cone shape, of a standard point. As such, it allows the needle to actually slice in a knife-like fashion.
This slicing action has proved to be a giant improvement when needling into a support base or a backing made of foam. Standard cone-shaped points tend to create problems by producing a buildup of foam, or fiber and foam, on or near the point end of the needle. The Chisel Point eliminates or greatly reduces this buildup, which causes frequent board cleanings, needle breakage and loom downtime.
