When Dave reviewed the previous incarnation of the Birzman Damselfly chain tool he wasn't overly-impressed given the price. So does the 2015 Damselfly Universal deserve better?
Firstly let's be clear here. Birzman have re-designed the Damselfly, and now offer two options: the Damselfly, and the Damselfly *Universal*. We're looking at the Universal variant here. So what do you get for an extra £15 (based on RRP) over the original Damselfly?
The key difference is in the spring-loaded retainer plate. This adjusts to the thickness of your chain's plates, meaning the chain is held tight against the load-bearing face of the tool regardless of dimensions. Hence Birzman can now say the tool is good for BMX, single-speed, 9, 10 & 11-speed chains, as well as older 6, 7 & 8-speed ones. The only chain it can't do is 11-speed Campagnolo, which requires peening. For that Birzman offer the Dragonfly at £50 RRP. The original Damselfly is restricted to 9 & 10-speeds only.
Much more expensive tools like the Pedro's Tutto have fixed 'teeth' that the chain sits over, and the thickness is adjusted using a wheel behind the chain to ensure a snug fit and that the pin is driven out or in squarely. This complexity costs, so the movable teeth-plate option is a smart design that just works.
One of Dave's gripes with the Damselfly was that the chain wasn't held in the tool, requiring a few extra hands to make the job painless. With the spring-loaded plate holding the chain the problem is sorted. The wide 'wings' and the pistol grip afford plenty of purchase and leverage to shift the most stubborn pins with precision.
A bonus is that the gap in the 'pin receptacle' end of the tool has been narrowed, so it can be used to snap off the excess bit of a Shimano joining pin - no need to reach for the pliers.
At 242g it's a hefty tool and the matt-black finish is certainly premium, even if the angular design may not be for everyone. There's a spare rivet pin included for when you wear out the first one - but that'll probably be a fair few years, even with frequent chain fettling.
Premium shop-ready tool for sensible cash; covers all chains bar 11-speed Campagnolo and will last a home mechanic a lifetim

My benchmark has to be the class-leading-for-remotely-sensible-money Pedro's Tutto, which at over twice the price does basically the same job, except it peens Campy 11-speed too. On this basis, and given it comes with a replacement pin, looks snappy and feels pro, the Damselfly Universal gets a 'Very Good'.
