What is a Grappling Hook?

S. Mithra

A grappling hook has three or four sharp, metal hooks curving outwards from a central rod. An eye at the end of the rod allows you to attach a length of rope. A fisherman, ninja, or climber throws a grappling hook to a high cable, tree, or wall, where it's bound to bite into wood or catch on an uneven surface. Then they scale the obstacle by pulling themselves up the rope or swinging from one ledge to another.

Grappling hooks were routinely used to assault high castle towers during the Middle Ages.

Historically, warriors and ninjas used a grappling hook to climb over walls and into trees. Japanese warriors used one type, called a kaginawa, as a climbing aid as well as a weapon. They swung the kaginawa in small circles by holding the rope close to the hook. Working up momentum, they expertly launched it at an enemy to trip them in a tangling rope or impale them with pointed hooks. In China, kung-fu practitioners used the fei zhua, a "flying claw" to reach higher ground on cliffs and buildings. It doubled as a heavy, barbed weapon.

Climbers use a modern form of a grappling hook.

Centuries ago, fisherman on large trawlers would use a grappling hook to swing between ships. If one ship was heading into bay, fisherman chose to 'catch a ride' to land when they were done trawling. Rather than boating or swimming over, the men were safer tying themselves to ropes and hooking onto cables of the ship that held the sails. Then they swung from the sails of one ship to land on the next one. Since grappling hooks resemble several large fishhooks tied together, their origin may lie with the ocean.

Climbers need a modern grappling hook, made with one flat, wide hook, to access mountains and caverns. These are often used in the controlled environment of an interior climbing wall, with ledges, cliffs, and outcroppings called flakes. Their edges are designed to hold a device shaped like the chunky grappling hook. Climbers practice for outdoor mountaineering or enjoy such sport as a hobby.

Today, we are more likely to encounter a grappling hook in a role-playing game than any real life situation. It lends itself to adventures where a character must scale a castle wall, climb a rocky mountain, or move between levels of a building with flair and ease. Knights, gnomes, and superheroes store the self-propelling and self-winding grappling hook in their belt along with other mythical tools.

I have a ninja grappling hook that I got in Chinatown. The barbs at the end look like dragons. It is more of a show piece than something you would actually use but I tried it once and it works.

I also have several swords and throwing starts and I display them all on the wall in my man cave. I have always been fascinated with ninja culture and I watch a lot of Kung Fu movies so it just makes sense to put the stuff up on the wall.


I have seen a lot of cheap toy grappling hooks but I want to buy a real grappling hook, something that could actually help me climb up the side of a brick wall like they do in the movies.

Where can I find something like this and how much would it cost? I have looked online to try and buy a grappling hook but I have not found the selection I am looking for. Any suggestions?

I had a grappling hook as a kid. Looking back on it it was probably not the safest toy to have. It is kind of just asking to get hooked in to someone's arm or to send someone toppling down the side of a building. But nothing too bad ever happened and I had a lot of fun with it.

I ended up losing it because I threw it up in to a tree and it got stuck very firmly on a branch. There was no way to climb up there and I could not get it unstuck so I just had to leave it.
