Preparation and Safety Guidelines

Tools Needed
  • Camp foam pad
  • Piping insulation
  • 3/8 inch rope
  • Fabric
  • Exercise pad (optional)
  • Fiberglass rebar or graphite golf club shaft
  • Electrical tape
  • Cloth tape (hockey/athletic tape)
  • Double-sided rug tape
  • Duct tape
  • Contact cement
  • Gorilla Glue
  • Measuring tape
  • Hacksaw
  • Utility knife or steak knife
  • Marker
Safety Guidelines
  • Never aim for the head or face. Even foam swords can cause serious eye injuries.
  • Use appropriate padding and protective gear, especially for sparring. Consider eye protection, gloves, and possibly even a mouthguard.
  • Inspect your foam swords regularly for damage. Discard or repair any significantly worn or broken swords to prevent injuries.

Step-by-Step Instructions

  1. Planning and Core Preparation

    • Decide on sword length and cut the core (fiberglass rebar or golf club shaft).
    • Mark and cut the handle section (approx. 1/3 of total length).
    • Prepare the blade section by trimming the golf club shaft (if using) and applying double-sided tape.

  3. Blade Preparation

    • Measure and cut the foam strips for the blade (five strips, 2 1/2 inches wide).
    • Apply contact cement to the foam strips, ensuring full coverage, and let it become tacky.

Tips

  • Use a snug but not overly tight grip when wrapping rope around the handle.
  • Contact cement requires a tacky, not fully dry, state for optimal adhesion.
  • Allow Gorilla Glue to fully cure (at least 24 hours) for best results.
  • Make the fabric cover slightly longer than needed for easier attachment.

Common Mistakes to Avoid

1. Using the wrong type of foam

Reason: Incorrect foam density can lead to injuries; too soft and the sword will be ineffective, too hard and it can cause bruising or worse.
Solution: Choose a foam with a density specifically designed for foam sword combat.

2. Poorly constructed hilt or blade

Reason: A weak hilt can break during combat, and a poorly shaped blade can cause injury through unintended sharp edges or weak points.
Solution: Reinforce the hilt with additional layers of foam and tape, and ensure the blade is smoothly sanded and free of sharp edges.

3. Ignoring safety precautions

Reason: Not wearing protective gear or engaging in unsafe combat practices (e.g., hitting the head or face) can lead to serious injury.
Solution: Always wear appropriate safety gear, such as eye protection and padding, and establish clear rules and boundaries for safe combat.

FAQs

What type of foam is best for making foam swords?
EVA foam (ethylene-vinyl acetate) is the most popular choice for its durability, flexibility, and ease of cutting. Closed-cell EVA foam is preferred as it's more water-resistant and less prone to absorbing sweat.
How can I ensure my foam sword is safe for combat?
Use rounded edges and avoid sharp points. Properly reinforce the core with additional layers of foam or a strong rod for durability and impact absorption. Always practice safe combat etiquette and wear appropriate safety gear such as protective eyewear.
What tools do I need to make a foam sword?
Basic tools include a sharp utility knife or box cutter, strong adhesive (like contact cement), a heat gun (optional, for shaping and smoothing), measuring tape, and a marker for drawing patterns. Consider safety glasses and gloves as well.
