This is a very very versatile tool, The Laser pick is ideally suited for ice climbing and can be changed for mixed climbing with ease. At the bottom of the tool there is a hook that you can rest a hand on instead of a leash, which allows for less pump and a bit up from this there is another smaller hook which is basically another hand rest which makes grabbing the tool with both hands without cluttering the handle very easy - great little feature. The tool can be fitted with a leash too. At the back of the shaft there is a removable hex screw which can be swapped for an attachment point for a leash which again allows for you to rest your hand and obviously prevents you dropping it ! The adroid Leash for the Viper is fully removable with a simple clip mechanism so the transition between removing and re engaging the leash is seemless, very easy and hassle free indeed. The weight of the tool balances really well as well so it just feels nice to use, definately a product for extreme situations,perfectly crafted and incredibly well designed. I'd never use another tool now having climbed with this one
