How to Make a Foam LARP Dagger

Live Action Role Playing (LARPing) is a fun and immersive experience where participants engage in storytelling through physical action, often using costumes and props to enhance the realism. One popular prop in LARPing is the dagger, and many enthusiasts prefer to make their own to fit their character’s needs. Here’s a straightforward guide on how to craft a foam LARP dagger, ideal for beginners and young participants.

Materials Needed:

  • Craft foam sheets (1/2 inch thickness recommended)
  • Duct tape
  • PVC pipe (1/2 inch in diameter)
  • Utility knife
  • Scissors
  • Contact cement or spray adhesive
  • Acrylic paint (optional)
  • Paintbrushes (optional)


1. Design Your Dagger

Begin by sketching the shape of your dagger on paper. Aim for a simple design, especially if this is your first crafting project. Once you have something you like, cut it out.

2. Cut the Foam

Place the paper template over your craft foam. Trace the outline with a marker, then use a utility knife to carefully cut out the shape. You may need to stack and glue several layers of foam to achieve the desired thickness.

3. Create the Handle

Cut a piece of PVC pipe to serve as the handle; about 4-5 inches should suffice. This will be the core of your dagger and will help maintain its structure.

4. Attach the Handle

For thicker foam, you can slit the base of your foam dagger and insert the PVC pipe inside. For thinner foam, wrap the foam around the pipe and secure it using your chosen adhesive.

5. Reinforce the Dagger

Strengthen your dagger by wrapping the blade area with duct tape. This not only adds durability but also provides a smoother finish. Ensure all sharp edges and rough areas are covered.

6. Decorate Your Dagger

Personalize your dagger by painting it. You can simulate a metal blade or choose any design that complements your LARP character. You can use many types of paint, including spray paint. Make sure your paint won’t degrade the foam.

7. Testing Your Dagger

Gently test the flexibility and safety of your dagger. It should be soft enough to not cause injury, making it perfect for LARPing.


Crafting your own foam LARP dagger not only adds a personalized touch to your role-playing experience but also provides a great opportunity to learn basic crafting skills. Daggers are just like LARP swords but shorter. Remember, the key to a successful LARP prop is creativity and safety. Enjoy crafting and happy LARPing!
