šŸ”Ŗ Hacksaw Through Arm Illusion – Sliding Blade Trick

This is a visual illusion prop designed to look like you’re cutting a hacksaw straight through your arm!

The secret is in the mechanism… the ā€œbladeā€ section slides in and out of each side, creating a super convincing effect that it’s passing through your skin.

Move it back and forth and it genuinely looks like the blade is cutting deeper 😳

šŸŽ„ Perfect for Reactions

Ideal for:

  • Social media content
  • Magic performances
  • Pranks & reaction videos

It looks impossible and gets great reactions from every angle.

🧠 How It Works

The blade is split and aligned with the frame so each side moves independently.

This creates the illusion of a continuous blade travelling through your arm.

šŸŽØ Colour Setup (AMS Recommended)

  • Designed to be printed with 2 colours using AMS
  • This covers the connection as the ā€˜blood’ line…

No AMS?

You can simply flip the blade around and add a bit of ketchup (highly recommended even with the AMS šŸ‘€) for an even more realistic effect.

šŸŽ­ Performance Tips

  • Start slow, then increase speed for the ā€œcuttingā€ illusion
  • Keep your arm relaxed for best alignment
  • Add ketchup or fake blood for maximum impact
