Semperfli Micro Metal Hybrid Thread
Semperfli Micro Metal Hybrid Thread is a hybrid material combining thread, wire, and metal to create a striking metallic sheen. It is ideal for crafting flies with a visible rib, especially for dries, nymphs, and saltwater patterns. This lightweight strand offers the appearance of a metal rib without the heaviness of traditional wire, making it perfect for larger flies where weight balance is important.
Constructed with a thin metallic tinsel layer over a soft poly core, the thread provides both strength and a natural metallic finish. It can be used for ribbing on fly bodies or as a decorative element on thoraxes.

Mary Hunter –
I’ve used this thread for several dry fly patterns and it adds a nice metallic touch without making the fly too heavy. The rib is visible and holds well during casting. Great for larger dries where balance matters.

The thread winds smoothly and the sheen is impressive. I used it on a salmon dry and it looked professional. It’s lighter than wire, which helps with flight performance.

Perfect for adding a subtle metallic rib to nymph patterns. The core is soft and doesn’t fray. I’ve tied over 20 flies with it and none have broken during use.
