Made by Mochizuki Spiral Piton Modeled after Salewa's Wart Hog, which was originally designed as an ice piton, it was created to be effective on frozen grassy slopes, which are common on Japanese winter rock faces. It has been affectionately called "Warthog" and has been a favorite among alpine climbers. This item belonged to my mountaineering-loving father. The purchase date is unknown. I am selling it to declutter. I am also selling other climbing equipment. I will do my best to offer a discount if you purchase multiple items. Please check the condition in the photos. There is a slight rust spot in one place (photo 9), but it is likely unused. I am open to price negotiations depending on the item, so feel free to comment. When negotiating the price, it would be helpful if you could provide your desired amount. Please purchase if you understand that this is a used item. Please refrain from purchasing if you are sensitive to such things. If you have any concerns, I can add more photos, so please comment. I will ship within 48 hours. The tip will be protected during shipping. No pets, no tobacco smell.
