How to make a Halo Energy Sword that WON'T Kill You

About this video

ZNA Productions designs and builds a functional energy sword inspired by the Halo video game, incorporating safety improvements like a wrist strap to protect against misalignment. The build combines machete blades, steel components, and wooden scales, demonstrating problem-solving around the original design’s dangerous wrist spike geometry. The host tests the finished weapon and reflects on the engineering trade-offs between form and function.

Key takeaways

• Identify design flaws in existing products and engineer practical solutions—ZNA recognized the original energy sword’s unsafe wrist spikes and redesigned them into a protective strap
• Use temporary fastening methods strategically; ZNA employed epoxy as a holding solution before permanent riveting, showing how to validate assembly before committing to final joinery
• Account for user error and physical limitations in your designs; ZNA added safety features specifically because human hands differ from the alien anatomy the original design assumed
• Iterate through finishing techniques like body filler and painting to achieve both structural integrity and aesthetic polish on improvised weapons and tools
