Triangular Needles:
This needle has a triangle-shaped shaft or a working tip with regularly shaped notches on the three edges.
Star Needles:
This needle has a four-sided shaft with regularly spaced notches. It has a vertical line running down it so it gathers more wool.
Spiral Needles:
This is the triangle needle shaft that has been twisted. The spiral needle penetrates the wool more efficiently and deeply.
Reverse Needles:
Reverse has shaft facing the opposite direction of regular needles, so instead of pushing fibers in, it pulls them out. This can blend fiber, add texture, create fuzz, or correct mistakes.
