I love tying with SemperFli Nano Silk! It's by far the strongest thread I have found, and I have yet to accidentally snap my thread off while tying with this. It does make termination slightly difficult, and I would recommend using sharp all-purpose scissors or a sharp knife to cut Nano Silk. Certain patterns, especially anything where you have to really cinch down materials like foam, would benefit greatly from being tied with Nano Silk.

Great strong thread and the staff is great 👍

Toughest, best thread available!
