    Cypher made the Firefly II Screwlock Carabiner superlight for alpine climbs. Its hot forged construction keeps the Firefly strong despite its weight, and it sports a secure screwlock gate for reliable anchor setups. There's a keylock nose for snag-free convenience.

    High Quality

      I picked up a few of these for some anchor work and just having some locking biners around is always useful. I was pleasantly surprised to see how smooth the screw lock and gate operate on these things. They are smaller which is perfect for keeping them around for some quick anchor work. And as the other reviews state, they are nice to look at.


      • Familiarity: I've used it several times

      I bought several of these to replace some well worn black diamond lockers and couldn't be happier with them. The screw lock is smooth smooth smooth! The finish is a lot prettier than the picture if that matters to you. What really matters is that these little lockers are very well made and don't break the bank.

      Small, light, and bomber!

      • Familiarity: I've put it through the wringer

      I love having a bunch of little lockers around for all sorts of reasons. This thing is awesome, just as strong and as light as the leading competitors and it's gate action is super smooth - so is the screw lock!
