The long stem can be used to clear the tube of an ice screw.
The Petzl Multihook can be used for a number of things, like threading your anchor and clearing the tube of an ice screw, or you can take it rock climbing to clean stoppers and cams. The 8mm wrench incorporated below the handle gives you a convenient way to tighten your bolts right after you thread your anchor.
