For the smallest flies you can split Nano Silk Ultra to form dubbing loops and still avoid build up but still tie with little thread of fly breakage. This line is an absolute Cobweb killer!

Semperfli Nano Silk

So 50 dernier Semperfli Nano silk has really stormed the fly tying world, many tyers using this amazing, ultra strong thread. Now however with the advences in manufacturing we have been able to take it one stage further and finer. Nano Silk 18/0 or 30 denier!, ideal for ultra small flies sizes 18 to 32. With stunning ability to split it can be used for dubbing twisting for ultra fine flies with no build up!

We love Semperfli Nano Silk as a fly tying thread, measuring 12/0 or 50 denier this is an incredibly thin fly tying silk which is virtually unbreakable, so strong that we decided to do a little experiment with this thread. We used size 8 hooks in standard wire gauge from a top hook manufacturer. Twisting Semperfli Nano Silk around the hook, we spun as it is an untwisted thread (meaning it can be split down even smaller if required) around the hook as if we were tying a fly then pulled holding the vice tight. Because we anticipated the results we made sure we were wearing glassed for protection, even Sandy Dickson was surprised at the results! We managed to break the hook 3 times on the trot and had great fun proving that Semperfli Nano is amongst the strongest fly tying silks in the world. We love Semperfli Nano Silk for extra small dry flies as there is no build up from this stunningly thin 12/0 silk (50 denier). When tying large Pike flies we can pull it tighter than any other silk which causes Bucktail to flare out to produce amazing Octopus Pike flies or simple elk hair caddis flies for trout. Check the video above as it shows just how strong Semperfli Nano Silk really is!
