Ice Tool The Black Diamond Viper has been updated for the 2015/16 winter! New features on the Black Diamond Viper? First of all, it's obvious the tools are lighter than the previous model - by at least 50g each - and that reflects current tastes. In fact the Adze tool is 595g and the hammer is 570g. It is now beefed up with a T rated Titan pick for rough mountain terrain. B rated Laser picks can be fitted for harder water ice if you wish though. The new Black Diamond Viper also has an adjustable upper hand rest which is easily secured or released with a quick FlickLock system. The hand rest can be as low as the TPU hand grip or as high as the shaft mid-point. The hydroformed shaft extends through the grip for maximum rigidity and a responsive feel. As before the Viper has a clippable spike so it can be clipped with the Spinner Leash amongst other things. The Black Diamond Viper provides good all-round performance for ice and alpine climber.
