Hacksaw Through Arm Trick/Prank

🔪 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 “blade” 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 😳

🎥 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.

🎨 Colour Setup (AMS Recommended)

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

No AMS?

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

🎭 Performance Tips

• Start slow, then increase speed for the “cutting” illusion
• Keep your arm relaxed for best alignment
• Add ketchup or fake blood for maximum impact
