Semperfli Fly Tying Wire Thin 0.1mm Copper
An ultra-fine, non-tarnish fly-tying wire (≈ 0.1 mm diameter, ~38 AWG). It is lacquer-coated so colors stay bright and it will not blacken your flies.
Why Pick 0.1 mm (vs 0.2 / 0.3 mm)
- Feather-light ribbing on #16–22 dries, nymphs, and midges without adding bulk.
- Subtle segmentation on slim buzzers/chironomids.
- Counter-ribbing for durability over quills/herl without overpowering the body.
- Micro weighting where you want a touch of sink but not a clunky profile.
Typical Uses
- Ribs: PTN, Hare’s Ear, quill bodies, RS2/WD-40, Zebra Midge (fine rib), Diawl Bach/Cruncher (river & stillwater).
- Buzzers/Chironomids: fine open-turn ribs in #14–20.
- Spiders/soft hackles: subtle wire tag or rib that does not widen the silhouette.
- Reinforcement: counter-rib over peacock, stripped quill, or biot bodies.
- Two-tone ribs: twist two colors of 0.1 mm together for a candy-stripe effect without adding much mass.
Wire Colors
Available in a wide palette: classics (copper, gold, silver, black, gunmetal) plus hot tones (e.g., red, orange, chartreuse) and naturals (brown/olive). The clear lacquer keeps colors bright and resists tarnish.
Pro Tying Tips
- Helicopter off the tag end (twist until it snaps cleanly) to avoid flattening it with scissors.
- Keep steady, light tension so turns sit tight and even; avoid over-tension that causes kinks.
- For counter-ribbing, use slightly wider spacing so the wire shows through dubbing/quill.
- On tiny hooks, start the rib one turn back from the tail to keep the abdomen slim.
- If using with slotted beads/jigs, check that the slot does not trap the wire—tie off a turn or two behind the bead before seating.
- Want more presence but the same sink rate? Double the wire (two strands in parallel) rather than jumping to 0.2 mm.
Quick Fly Tying Wire Chooser
- 0.1 mm: micro ribbing, #16–22, delicate flies, minimal weight
- 0.2 mm: general trout ribs, #12–16, stillwater lures/nymphs
- 0.3 mm: bold ribs/tags, #8–12, streamers/larger nymphs
Each spool of Wire 0.1mm contains approximately 30 m / 32.8 yards.
We developed and manufactured our own computerized spooling machinery, and Wire 0.1mm is wound onto the spool with touching turns in a completely level traverse. Why is this important? With Wire 0.1mm, you will not get a bird’s nest when tying flies or have wires trapped. Our spools have a removable cap so you can re-trap the wire after removing a section to tie your flies.
