This is a Black Diamond spinner leash. It attaches to an ice axe to prevent accidental drops. I purchased it 3-4 years ago. I haven't used it much. I checked it thoroughly before listing it. Strength: 2kN. The rubber has good tension, the carabiner is in good condition, the spinner is in good condition, and the sling has no scratches. Please refer to the photos for details. I am selling it because I can no longer do ice climbing this year. Thank you for looking.
