The Birzman Dragonfly Chain Tool would make a welcome addition to any shop, and that assumption is based on its looks alone. Beauty is much more than skin deep in the Dragonfly's case, however. The Dragonfly is made with super durable forged aluminum. It's CNC machined for incredible precision, and the T handle provides added leverage so you aren't working so hard on the chain that you botch the job. The patented interchangeable cradle is designed for 11 speed chains, and it's reversible to accommodate 9 and 10 speed chains, as well.
