Our titanium grappling hook is a great EDC tool with many uses. The (very sharp) spikes are 1.5 inches and the container with the lid on is 2.5 inches long. The spikes fit into the container nicely. The container is waterproof and can also be used as a storage container for pills, cash, or other small valuables. The spikes can be used as toothpicks, wedges, or of course as a grappling hook. The grappling hook comes with the mini D-ring shown that you can tie paracord to or use for a variety of other things as well. (does not come with paracord or bead)
This is not designed to be used to support human weight.
