This tool is used when a camming device gets stuck in a rock and cannot be removed. The tool is used to pinch the trigger ends of the cam with the holes at the tips of the tongs and pull it out. Easier to retrieve than using a nut key alone! An essential item to help retrieve expensive camming devices!! This is a custom-made item, so it cannot be purchased at general mountaineering equipment stores. The usage is as shown in the picture. First, pinch the cam's trigger with the cam retrieval tool. While pushing the thumb hold with a nut key, etc., grab the retrieval tool and pull out the cam to complete the retrieval! *The sale item is only the tong-shaped tool in the photo; carabiners and cams are not included.
