Climbing cams are ingenious, and anyone who has hung from their fingernails while desperately trying to place a nut in a flared crack knows just how reassuring a good placement can be. They come with 3 lobes (light, able to fit into small slots and awkward places) or 4 lobes (a little heavier and wider but many climbers feel 4 lobes is more stable). If you're looking for a good gift for a rock-loving friend, look no further. A climber can never have too many.
