Picture of Watermelon Smasher (Post-Apocalyptic Spiked Mace)
They are coming.  Make no mistake about it.  The watermelons will rise, and when they do, nothing can stop their insatiable need for human flesh.   Guns?  Too loud.  Blades?  Too easy.  In the chaos to come, you will need a weapon that can be made with simple household items and requires no maintenance.  Behold, the destructive simplicity of the WATERMELON SMASHER!!!

***Cold Steel used to make a battle mace, but it is discontinued.  I saw one recently on eBay for over $50.  This is my attempt at a homemade version.

Step 1: Safety FIRST

I am dissapointed that I have never really discussed safety in any of my previous instructables.

Protect yourself.  I use safety glasses, hearing protection (around power tools) and work gloves at a bare minimum.

Could I use a broomstick for the handle? I try this as it seems like an excellent idea.

I went with cast aluminum. Also ran a 4"bolt out the end, to stab/slash with. Length about the same as yours. To keep the handle from wearing/splitting I wrapped it with metal duct tape to fill the gap. My photo didn't turn out. Will try later.

"This version is pretty heavy (the head assembly weighs 5 lbs.) I would like to make a shorter, one-handed version that weighs less than 2 lbs."

I see what you did there. You added weight to the head so the can doesn't collapse. Very nice touch. This is the best DIY design I've seen in 15 years on the internet.

This. Is. Brilliant.

My brain is already racing to figure out a spherical-mace version. Perhaps by putting two identical metal bowls together?

Or a spiked-ball-on-a-chain version...
Heres something you may be interested in. Youth sized bat with long screws or nails going thru it ever which way but loose. Almost have mine done.

Awesome! Gotta make this! I agree, gotta design a 2 lbs. version. I remember an old version of a mace, but it uses a youth sized bat and screws or nails. Wouldn't recommend that one for the kids of course. lol

Nice idea, if you want to make it more durable use threaded rod and go through both sides of the can.

I made one and it works great :D thanks man! I will be using it for a post apocalyptic film for class

are you using a regular soup can? I am going to do this with a small coffee can (bigger than a soup can to make a slightly larger one) what size bolts should I get?
zap1998 (author)  Broman1851 year ago
I used a regular soup can, and 1/2" bolts that are 1-1/2" long. Good luck!
Could you tell me where you got the wooden handle from?
zap1998 (author)  Halflimey_jt1 year ago
I used a broken shovel handle that I had. You can buy new handles from Home Depot or Lowe's for less than $10.

@DoctorFrost I found a smaller coffee can made by nabob this may help you if you want to make a 2-3 pound version

I like the idea and that a smaller one hand 2 pound WS(P-ASM) Is now seeded into our minds maybe we'll see some 2-3 pounds single hand versions.

I need to do more "testing" this weekend. LOL

Excellent project. I think the only 'mod' I would make is to at a few points to the tip so that it could also lance if your unable to have enough room for a full swing.
zap1998 (author)  mszymczak2 years ago
Great suggestion. I am planning on making a lighter, one-handed version; I will have to incorporate a lance/spear on that one.
It's a beauty.
