Introduction: Grappling Hook
As I mentioned in this Instructables, I went kayaking with my friend. We were kayaking down the river and saw an amazing rope swing. As we approached we realized it would be impossible to use without losing our kayak. What we needed was a hook.

Step 1: Tools/Materials
- Laser cutter
- Disposable cup
- Scrap wood
Step 2: Design
I did some research and thought for a while. I didn't come up with anything revolutionary, but I came up with something functional. That would have to do. There are three holes on one end, to enable easy tying. There is a hook on the other end to hook too small branches and rope. The hole in the middle allows the rope to attach to larger objects. Keep in mind functionality while designing your hook (if you do design your own).
Step 3: Cut/Sand
Cut the acrylic and wood parts. Leave the protective cover on the acrylic as long as possible. Sand the wood, as it will most likely have smoke residue from the laser.
Step 4: Assemble
At this point, you can take off one of the protective layers from the acrylic so it adheres to the wood. Mix up some epoxy and epoxy the acrylic onto the wood. I sandwiched the wood in acrylic to maintain a balanced look. Make sure to put a lot of pressure on the acrylic while the epoxy hardens, otherwise it will look ugly and be weaker.
Step 5: Sand, Paint, Sand
Sand all the edges so the hook feels nice in your hand. Then paint it. I used a clear coat because I like the look of wood. Once the paint is cured, lightly sand it until smooth. You are now done with the hook; the following steps explain different uses.
Step 6: Attaching Rope
As I previously mentioned, the three holes in a triangular orientation are for attaching a rope. Follow the images step by step.
Step 7: Hook
The hook is not the strongest part. However, it is easy to use and strong enough for many things.
Step 8: Easy Loop
The easiest and quickest loop is made by putting the rope through the hook or the middle hole.
Step 9: Medium Loop (carrying Stuff)
As the name implies, this loop is ideal for carrying things like (like wood).
Step 10: Complicated Loop
This loop will not slip. This is one way to shorten the rope.
