Thread

The combination of strength and small diameter makes this our go-to tying thread. Because Nano Silk lays perfectly flat you get no thread build up. 

Size: 18/0 (30 Denier), 50m (54 yards) spool.

Classic Waxed Thread 12/0 70D been designed specifically for fly tying for midges, emergers and dry flies and is recommended for hook sizes 10 to 20.

This thread lays flat with a two core construction but can easily be split to create dubbing loops

This is quickly becoming our favorite material for tags and ribs on hot spot nymphs and other applications where we historically used thin strands of floss.  

No tyer can be without a range of fluoro threads in their tying kit and Fluoro Brite is a great choice. Fluoro Brite is a twisted fluorescent thread. To get it to lay perfectly flat simply untwist with your bobbin holder. Fluoro Brite has been specially formulated for fluorescence and comes in 240 denier (3/0). Fluoro Brite, used as a thread or a floss, is recommended for hooks 10 to 2/0 but if you want to use it for smaller flies simply split it down further. Use it as a hotspot, for ribbing, a body or even a fab hot spot tail!. For tails we fold Fluoro Brite four times in a loop and tie it in the tail of a fly, cut to length then tease the fibres apart with a dubbing brush and you get an astounding crinkled tail with what looks like little firelights on the tail of your fly.

Since Joseph Keen's book - Fluorescent Flies (1964) and Thomas Clegg's book – The Truth About Fluorescents (1967) fly tyers have been working with fluorescent materials. We decided to make a fluorescent thread with advantages that it could be used as a tying thread or as a floss, could be untwisted with the bobbin and used as a floss. Fluoro Brite was born to be different. What is well known is that fluorescent materials do attract trout, salmon and other species. We cannot see material effects except under a UV torch where we see the glow. But with their visual rods and cones capable of seeing into the UV spectrum many fish species see this like a light in the dark. Fluorescent materials work well one hour before daylight and one hour after nightfall. This is because even though we cannot see them, UV rays from the sun still hit the water and ignite your flies.

There are 25m / 27.3 yards (approx ) per spool of Fluoro Brite

Here's an example of how we use it:

MIDGE: These jaws undergo the same hardening and tempering process as our highly acclaimed standard jaw. Our midge jaws are specifically profiled to allow more access to tie on smaller hooks. Black oxide finish looks clean and reduces glare in the immediate area of your fly. PEAK Midge Jaws are available for both the PEAK Rotary Vise (MDG-1) and the PEAK non-Rotary Vise (MDG-NR). Not recommended for extended use with hook wires larger than a #16 dry fly hook.

SALTWATER: These jaws undergo the same hardening and tempering process as our highly acclaimed standard jaw. They will accept hook wire diameters from approximately .040″ to .075″. The black oxide finish looks clean and reduces glare in the immediate area of your fly. PEAK Saltwater Jaws are available for both the PEAK Rotary Vise (SLT-1) and the PEAK non-Rotary Vise (SLT-NR).

Replacement jaws for the Raven and Wolf Rotary Vise

Different to other flosses on the market Semperfli Floss is a thin floss. At 400 Denier, it can be used for smaller trout flies and simply doubled over for use on Salmon.. By creating a thinner fly tying floss the capabilities and uses of this material are enhanced so it can be used as the body for flies of many sizes.
