Create strong, long-lasting beadwork with The Beadsmith Fireline by Berkley, a micro-fused braided thread made from Dyneema, one of the strongest fibers by diameter. This 4lb test, 0.005” (0.12mm) smoke grey thread is perfect for bead weaving and fine stringing projects where you need slim but incredibly tough thread that resists fraying.

Why you’ll love it:

  • Made from Dyneema gel-spun polyethylene for exceptional tensile strength in a thin diameter.
  • 4lb test, 0.005” / 0.12mm size is ideal for detailed bead weaving and delicate jewelry designs.
  • 50 yard spool in smoke grey, a versatile colour that blends beautifully with many bead palettes.
  • Originally developed as premium fishing line and now a favourite among beaders worldwide for its durability.
  • Works well with English beading needles (typically #12 for this size) and finishes cleanly with a thread burner or thread zapper.

Tip: Tie off your work with a knot and carefully melt the end with a thread burner to form a tiny ball that helps secure the knot and prevent unravelling.
