The pocket grappling hook was originally built by EOD Robotics, Inc. at the request of a desert warfare operator. He explained his need for a light weight, reusable grappling hook that could be used to snag trip wires or command detonation wires on IEDs in a combat environment. Soon other members of the military saw how useful they were and ordered another production run.

Features include:

• Pocket size: stowed size: 1" x 5.5 " (also fits in your collapsible mine probe pouch) 
  Weight (without water or sand ballast) 5 oz.
• Collapsable: The spikes unscrew and are stored in the water resistant O-ring sealed body.
• Variable weight: by adding sand, dirt or water into the body of the grappling hook you can increase the weight of the hook for more effective throwing range.

These hooks are not certified for life support activities and should not be used for any life support function. They are designed to pull trip wires.

• Versatile: Easy to carry, quick to deploy and quick to stow. 
  Multi-mission capable: Maritime applications, SWAT, EOD, radio telephone operator 
  Flexible: use it as a specialized grappling hook to remotely capture lines, tear down phone lines, reposition barbed wire emplacements, disrupt wires, move packages and bags, rake and break windows, tear down blinds/curtains in SWAT entry applications.
• Remove the spikes from the outside and use it to cast a line. This is currently being used by military RTOs (radio telephone operators) to string field expedient HF antennas.
• Use it as a waterproof storage container to protect important items from water damage (when the spikes are removed).
• Materials: The body is made of T6061 aluminum. The spikes are made of 300 series stainless steel.
• IMPORTANT: The pocket grappling hook is not designed for life support applications and should not be used for such applications. As with all tools, use with extreme caution.
