I invented the warhammer clamp.

In the Norse Lore, Thor has the convenience of a warhammer which, thanks to dwarven craftsmanship, reduces in size to fit in his pocket or be worn as a pendant (yes, anyone wearing a Mjölnir necklace could be that Odinson among us, so watch yourself). Yet, short of some atomic-chain matter folding nano-technology, bearing a warhammer for the rest of us tends to be rather cumbersome.

Many have stated that necessity is the mother of invention, or argued that war is the father of innovation. The medieval warhammer was invented as an anti-armor weapon, something that crushes & claws into plate steel. Aside from keeping this weapon in hand, or tucking it into your belt, there historically was no other easier method of carry. But why hadn't those knights & soldiers who'd worn a scabbard or quiver on their backs thought of something similar for their warhammer?


Five-hundred years later, Guillermo the IVth finally invents the warhammer clamp, adding his name to the Valhalla-worthy warriors of melee weaponry's historical innovations.

[The warhammer in clamp! And me in my wedding tunic!]

[Grabbing the haft for draw.]

[Drawing the warhammer.]

[Swinging over-the-shoulder for the strike!]

Mark that game changer on your calendars.


It started as a going-to-sleep exercise. I'd lie there and think of how exactly one could wear a warhammer on their back for a quick over-the-shoulder draw, and also be able to snap it back in place once done pounding your attacker into submission. Sometimes I'd slip into a dream thinking about it. Other nights, the mental exercise would cause my eyes to snap open, and instead I'd run for my desk to draft something out. As a writer, you learn that if you don't put an idea down when it comes, you will lose it, and I applied that preserving sensibility to this process.

[Warhammer dimensions.]

My awesome high finish warhammer from Sabersmith Inc has a hammered/scalloped haft, which is advantageous for grip, but presented a challenge for a clamp. The first two PVC pipes I dremeled into what would've been working shapes for a standard smooth handle finally worked on my third attempt, which had higher ends for holding an irregular surface, a scoop in the middle for flexibility to allow for a draw, and curved outsides to prevent scratches & not get caught when the hammer was drawn/replaced.

I then drilled & mounted the clamp onto a T-shaped plastic sheet reclaimed from two pieces of old computer keyboard that I Gorilla Glue'd together.

The next problem was the width of the head versus the smaller diameter of the handle while mounted. I'd thought the plastic backing would just flex and curve down for the wider head when clamped, but no, it required immersion in boiling water to soften and reshape into a specifically angled spatula to allow for the warhammer's head. (Thanks to my prop-making friend Tory Middlebrooks for this helpful tip.)

[Note the finished spatula shape, and the judicious use of Gorilla Glue between the layers, which requires some restraint & predictive skills as it expands to four times its volume when dry.]

With the hardware of it crafted, I then had to learn some basic sewing (since I took Spanish in both junior high & high school and not Home Ec.). Making a pattern, acquiring a yard of nice faux leather upholstery, and some high gauge waxed thread, I cut a front, back, and baldric loop. The front pleather required some careful assessing of how wide to make the slot to slip over the clamp portion. Before the first part of the stitching, I used Gorilla Glue to seal the edges of the loop. Using a ruler & a white gel pen, I then measured & marked the holes, punched them with a bookmaking awl I had, and did a double running stitch for the baldric loop on the back piece, then whipstitched around the outside halves after first Gorilla Glue-ing them down & together to the plastic hardware.

[The finished back with a loop for the baldric to run through. The loop had to be long for a solid mount of the "T" on one's back, otherwise it might twist and the clamp wouldn't release when one needed it to.]

[The front side with warhammer in place.]

Making a pattern of the finished tube clamp, I cut a sheet of adhesive backed black felt to cover it (see above and the third photo in this post for detail) and protect the hammer from scratches, then added one thin strip of adhesive backed foam rubber for extra grip on the four top insides of the clamp to prevent slippage while in states of excessive motion (i.e. jogging, running, rappelling, or horseback).

[With baldric belt running through the back.]

Sometimes in older issues of Marvel's Thor, we see him with the hammer's handle peeking out over his shoulder, but we never get to see the scabbard-like hardware as the head's always under the red cape, so the artist never actually had to present a working solution like this one.

[The last thing you might see before getting sent to Hel.]

I'm no engineer, so this project was challenging for me. I'd get super angry when things didn't come together the first time, as I'd spent alot of time thinking and re-thinking possibilities, trolling hardware store aisles, considering so many materials, looking at textiles, weighing the idea of maybe using rivets or grommets, and playing with the options over & over in my head, yet still buying things that didn't work or I didn't need. It wasn't like writing where the tools & words are superfamiliar and it feels like play at times -- this was strange & rather like work.

I felt maybe this was a small taste of what Sindri & Brokkr felt when making Mjölnir, the vision of knowing what you want to make but putting in all the effort into figuring out exactly how to make it as the horsefly of doubt & setbacks tries to break your concentration. It turned out to be three times what I thought it would be in costs & time, but it was worth persevering on until the victory of invention. I'm glad the plastic dust is out of my lungs and kitchen, and I can now carry my warhammer hands free and always at the ready.
