Used when a camming device gets stuck in a rock and cannot be removed. Grasp both ends of the cam's trigger with the holes at the tip of the tongs and pull it out. Easier to retrieve than using a nut tool alone! An essential item to help retrieve expensive camming devices!! This is a self-made item, so it cannot be purchased at general mountaineering equipment stores. The usage method is as shown in the picture. First, clamp the cam's trigger with the cam retrieval tool. While pushing the thumbhold 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.
