Semperfli Nano Silk 50D 12/0 Black

Its certainly strong but not the easiest stuff to work with. Splits very easily and very slippery. Difficult to cut cleanly. Will persevere though cos the strength is a big advantage.

I will only use nano silk. It’s the best!

Amazingly strong thread but very difficult to cut if not under tension.

very thin thread and very very strong do not try and break this with bare hands the finest thread I have used the only thread to use on very small patterns with even finer Nano thread available for the very small patterns good range of colours this thread will suit the majority of tyers

Excellent service....very quick. I don`t actually do any fishing - I build models but this string is very useful!

I have been a fly tying for a few decades now and been using nano silk since I met Mick and the family at Burton on Trent fly festival. I like to see/ touch materials I buy especially feathers and capes, with nano silk it's manufactured consistently to a high standard.its takes a little while to adapt to the silks strength and thickness when you first offer it to the hook but once you mastered this well small flies just keep rolling of the vice. Also getting used to the amount of tension to apply because you can cut through some materials. All in all very good tying thread Tring to reduce stocks of other brand as a result.

Pity they didn't have GSP forty years ago. Almost gave up tying due to being too heavy handed. I don't break this silk, but I'v bent a few hooks.

Good strong thread great for tying.

This thread is excellent !. Ultra strong, I can use less of it and still have secure tyings, it makes for a more durable fly. It gives me confidence in my tying, knowing it's unlikely to break which lets me be more creative !. Could this be the ultimate thread ?. Thank you.

Quite possibly the best thread I have ever used. Why would anyone use cheaper alternatives
