Carbon stick tips

Carbon Fiber Lace Needles from KnitPro/Lana Grossa are made of carbon fiber and feature plated brass tips. Carbon fiber is a lightweight and highly durable material that is also used in spacecraft and airplanes.
The brass tips are both durable and appropriately pointed.

Combine the lace needles with various cables, and you will have a circular needle that can be fully customized to suit your needs.
