Firstly, it's probably one of the best set of pliers you'll every buy (pliers are always handy on tour and at home)
Secondly, even though it's short, the way you hold it allows for a lot of torque and holding power so it can crank almost any bicycle spec'd hex head bolt to torque and open them as well. It can also open some hex socket bolts if they're not too tight.
Thirdly, you can use it to true brake rotors.
Fourth, a pot holder.
or whatever you can imagine a good set of small pliers doing.

Weight is 62 grams and it really is quite small
