A rope anchor with a J-shaped a body having a hook and spine. The end of the spine has an attachment hole for a rope and an elongated, teardrop-shaped rope slot that is either enclosed or gated. The gate is biased closed to span the open side of the rope slot and pushed opened to allow access for a rope. A tip, composed of a flat chip of metallic material, fits into a slot at the end of the hook. The tip is generally triangular with two or three sharp corners, or square or rectangular with four sharp corners. The slot orients the tip so that only one of the sharp corners is exposed, or so that two adjacent sharp corners are exposed. When an exposed sharp corner is not suitable for use, the tip can be reoriented to expose a different sharp corner.
