Petzl gear clips (ice screw holders) and an ice screw cleaner, though I don't know the manufacturer. The gear holder is for the second climber to attach to their harness and hold the ice screws after they've been retrieved. The screw cleaner is for quickly pushing out snow and ice from the screw. The hexagonal hole is used for tightening and loosening bolts, and the tip is hook-shaped for scraping away snow. When not in use, it has a cover for safety. I've painted below the hexagonal hole to identify it as mine. Both are essential for ice climbing and are attached to the harness when climbing.
