The first time I saw the image on Reddit, I did a double-take. A spiky wooden ball mounted on a pole, with screws sticking out like a medieval weapon straight from a battlefield, was lying in someone’s bush. My first thought was simple: Okay… somebody was either trying to build a weapon, or possibly the world’s most extreme gardening tool.

The original post came from r/whatisthisthing, a corner of Reddit where strangers gather to solve random mysteries. In this case, a new homeowner had pulled the object out of their front yard shrubbery. The ball, lined with screws, looked menacing, like a DIY mace someone had hidden away for no apparent reason. The caption was equally baffling: “Found this in my bush. What is it?”

As much as my imagination wanted to run wild—think horror movie intruders or backyard medieval reenactments—I quickly reminded myself: the simplest explanation is often the right one. People make weird stuff all the time, especially when they’re bored, trying to save money, or repurposing junk lying around.

Shaped Like a Weapon, But Probably Isn’t

Yes, it looks like a mace. I won’t argue with you there. I could easily picture a knight in chainmail swinging it around a castle courtyard. But in reality, who hides a homemade weapon in their front bushes? If someone were really trying to make a self-defense tool, they would have chosen something heavier, sharper, and more practical. The screws on this ball were terrifying—but not particularly effective.

Much more likely, this object had a practical purpose. Something satisfying a specific need, albeit in a strange, DIY way.

A DIY Lawn Aerator?

This theory quickly became the most upvoted suggestion on Reddit. Think of a lawn aerator: a tool designed to poke holes in soil, allowing air, water, and nutrients to reach grass roots. Most commercial aerators have metal spikes, but for a small yard, why buy an expensive tool when you can improvise?

Screws sticking out of a wooden ball could technically do the job. Roll it over the lawn, press it into the soil, and yes—you’d create holes. Not the most efficient design, but effective enough for a budget-conscious gardener. I’ve personally seen neighbors turn random garage junk into surprisingly functional yard tools, so this seemed plausible.

A Rodent or Pest Deterrent

Another idea: it wasn’t about grass at all—it was about what lives in the bushes.

In areas where snakes, wasps, or other critters like to hide, having a stick with spikes could allow someone to prod or shake a bush without putting their hands at risk. The screwball design might be a crude but effective way to “wake up” hidden wildlife and encourage it to move along.

While I’ve never felt the need to swing a screwball at a bush, I have used broom handles and other tools to poke at dark corners when dealing with spiders or wasp nests. A spiky ball makes sense for someone wanting a bit more “bite” when clearing out tricky shrubbery.

A Prop, Decoration, or Random Art

Perhaps it wasn’t meant to be functional at all. The ball could have been part of a play prop, a Halloween decoration, or a craft project gone astray. Metal-studded objects often appear in haunted houses or theatrical performances, and over time, these props can get discarded or misplaced.

I once watched a neighbor build an enormous paper-mâché dragon head for a school play. Weeks later, children in the neighborhood swore the thing was haunted. Maybe this DIY mace had a similar origin: a creative project, abandoned and forgotten, eventually blending into the bush until discovered.

An Ice or Snow Breaker

This suggestion required thinking outside the box but was just as plausible. In snowy regions, people often improvise tools to break compacted ice or frozen ground. A screw-studded ball on a stick could chip at ice in a pinch. I grew up in a snowy area and saw many creative solutions—shovels, crowbars, even frying pans—repurposed as snow-breaking tools. In that context, the “mace” isn’t ridiculous at all.

So What Is It?

We’ll probably never know for certain. Based on its construction and the ideas floated on Reddit, it likely falls into one of these categories:

• A budget yard tool, either a lawn aerator or a pest prod
• A seasonal tool, like a makeshift ice breaker
• A forgotten prop, decoration, or craft project

What’s remarkable about these mystery objects is how they reveal human ingenuity. Someone had a reason for creating it, even if that reason is now lost to time.

Next time you find a weird item in your yard, don’t assume you’ve stumbled across a medieval weapon. Examine it closely—scratches, dents, and other markings can tell a story of its purpose. Sometimes, the most bizarre creations have the most practical origins, and the kookiest objects often have the richest, most imaginative backstories.
