It is a image burned into our collective brains. A glittery box, a sharp saw, and a woman’s feet wiggling on one end while her head smiles from the other. You’ve seen it a thousand times. But honestly, most people have no idea that sawing a woman in half wasn't just some random trick; it was a cultural explosion that changed the stage forever.
People actually fainted. In 1921, when P.T. Selbit first debuted the trick at the Finsbury Park Empire in London, it wasn't the clean, sanitized version we see on TV specials today. It was visceral. He used a massive hand saw. He tied the woman's wrists and ankles. The audience thought they were witnessing a literal execution under the guise of theater.
The trick is a masterpiece of engineering and psychology. It’s about more than just "where did the legs go?" It’s about the tension between the impossible and the observable.
The Bloody Origins of the Great Divide
Before the glitz of Las Vegas, the trick was gritty. P.T. Selbit—whose real name was Percy Tibbles—didn't even use a box that came apart at first. He just sawed straight through a wooden crate. The woman inside, Jan Glenrose, had to stay incredibly still. It was dangerous. If the wood splintered or the saw slipped, the stakes were real.
Why did he do it? Competition. Magicians in the early 20th century were desperate for the "next big thing." The Victorian era of "gentle magic" with silk scarves and flowers was dying. People wanted thrills. They wanted to see something that felt like a headline from a penny dreadful. Selbit gave it to them.
Interestingly, he didn't call it "sawing a woman in half" initially. He called it "Slicing a Lady." It sounds way more aggressive, right? It worked. The stunt was so successful that he had to hire "nurses" to stand in the lobby with smelling salts for the audience members who couldn't handle the sight of the saw teeth biting into the wood.
Horace Goldin and the Mechanical Evolution
While Selbit started the fire, Horace Goldin turned it into a forest fire. Goldin was a Polish-American magician who realized that Selbit’s version was a bit slow. It took too long to saw through the wood. Goldin wanted speed. He wanted spectacle.

He refined the trick using a buzz saw. This changed the game. Now, instead of a slow, rhythmic rasping sound, the audience heard the high-pitched scream of a mechanical blade. It was terrifying. Goldin also changed the box. He made it so the head and feet were visible the entire time. That was the "aha!" moment for the industry. If you can see the person's face while the blade passes through their midsection, the brain just breaks. It can't process it.
How It Actually Works (The Mechanics of the Lie)
Okay, let's talk about the "how." You probably think you know. You’ve heard the rumors about two women being in the box.
Sometimes, that's true. In the "Two-Person" method, one woman is scrunched up in the top half, showing her head and arms. A second woman is hidden in the table or the bottom half, sticking her feet out. It’s a classic for a reason. It’s reliable. But it requires two people who are roughly the same height and have very similar-looking feet. If one girl has a tan and the other doesn't, the trick is ruined.
But there are other ways. Serious ways.
- The Beveled Table: This is a work of art. The table looks thin. Too thin to hide a human body, right? Wrong. Through clever use of mirrors, lighting, and "tapered" edges (the bevel), the table hides a deep cavity in the center while looking like a sliver of wood from the side. The assistant isn't being sawed; she’s just curled into a ball in a space you don't think exists.
- The Thin Model: This one is even more impressive. The magician uses a very long box and a very flexible assistant. She maneuvers her body around the blade in a way that seems anatomically impossible. It’s basically high-level yoga disguised as a murder.
- The Clear Box: This is the modern version. Pendragons popularized this. You can see through the box. There’s nowhere to hide, or so it seems. This relies on "black art" (using black velvet to hide shapes) and incredible speed.
Why Sawing a Woman in Half Still Matters
In a world of CGI, why do we still care? Because it’s physical. We live in a digital age where everything is fake, so seeing a physical object—a steel blade—pass through a physical body creates a unique kind of cognitive dissonance.
It’s also about the "Assistant." For decades, the woman in the box was nameless. She was a prop. But in modern magic, that’s shifting. Magicians like Dorothy Dietrich have performed the trick while flipping the script. Dietrich was one of the first women to perform the saw-in-half trick herself, rather than being the one in the box. It changed the power dynamic.

Magicians like Penn & Teller have even "deconstructed" the trick. They’ll show you how it's done, or they’ll use a clear box, and yet, they still manage to surprise you at the very end. That’s the hallmark of a great illusion. It’s not about the secret; it’s about the performance of the secret.
The Most Famous Variations You Should Know
Not all "sawings" are equal.
- The Zig Zag Girl: Invented by Robert Harbin in the 1960s. This is the one where the middle section of the woman is pushed out to the side. It’s iconic because it doesn't use a big, bulky table. It looks impossible because the middle is clearly gone.
- The Death Saw: David Copperfield took this to the extreme. He was tied to a table under a massive industrial blade. He didn't get out in time. The blade "split" him in half. No box. Just a man on a table. It was a masterclass in pacing and music.
- The Bow Saw: This is the old-school version. It’s slow, rhythmic, and focuses on the "sound" of the magic.
Common Misconceptions That Ruin the Fun
Most people think there’s a "trap door" in every stage. There isn't. Modern stages are often thin or temporary. Magicians can't rely on holes in the floor anymore.
Another big myth? That the assistant is always a "small girl." While being petite helps for certain versions of the trick (like the Thin Model), many versions rely more on flexibility and core strength than just being tiny. It's a grueling job. You are cramped in a dark, hot box, often upside down or folded like a pretzel, and you have to look "glamorous" the second the box opens. It's an athletic feat.
What to Look for Next Time You See the Act
If you want to "spot" the secret, you have to watch the table. Don't watch the saw. The saw is a distraction.
Watch the thickness of the table. Look at the shadows underneath it. Is there a weirdly shaped "trim" on the side of the platform? That's usually where the extra space is hidden. Also, watch the assistant's transition into the box. Does she go in straight, or does she do a little "wiggle" to settle her hips? That wiggle is her getting into the hidden compartment.

But honestly? Don't look too hard. The joy of sawing a woman in half isn't in knowing the answer. It’s in that split second of "wait, what?"
Actionable Insights for Magic Enthusiasts
If you’re fascinated by the mechanics of stage magic or want to understand the history better, here are the real-world steps to take:
- Visit the American Museum of Magic: Located in Marshall, Michigan, it houses original props from the legends, including Goldin and Blackstone. You can see the actual boxes. They are smaller than you think.
- Read "Hiding the Elephant" by Jim Steinmeyer: He is the guy who designs the illusions for Doug Henning and David Copperfield. He explains the evolution of the "divided lady" better than anyone alive.
- Watch the 1920s footage: Look for archival clips of P.T. Selbit. Notice the lack of music. The silence makes the sawing sound terrifying.
- Study Stage Lighting: If you want to understand how mirrors and "invisible" compartments work, look into "Black Art" techniques. It’s all about what the eye is allowed to see.
The trick is over a hundred years old. It’s been parodied in cartoons and used in horror movies. Yet, every year, a new magician finds a way to make it fresh. Whether it’s using a laser instead of a saw or doing it in the middle of a brightly lit street, the core remains: we love the idea that the impossible can be survived.
Next time you see a magician pull out that big crosscut saw, don't just look for the seam in the box. Appreciate the century of engineering, the physical toll on the performer, and the clever bit of geometry that makes your brain tell you a lie your eyes are forced to believe.
To truly understand the impact, you have to realize that this trick saved magic. It moved it from the world of "puzzles" into the world of "theatrical experiences." It gave magic its first real "blockbuster" moment. And that is why, even in 2026, the box remains on the stage.
