This tool is used when a camming device gets stuck in a rock and cannot be removed. It works by using the holes at the tips of the tongs to pinch and pull the cam's trigger. Easier to retrieve than using a nut tool alone! An essential item to help recover expensive camming devices!! This is a self-made item, so it is not available in general mountaineering 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.
