Wrist Mounted Crossbow



Here is an interesting DIY project--a wrist mounted crossbow.
Priebe doesn’t draw up designs for his projects; he just starts tinkering. In his home shop, he cut some bars from an aluminum sheet and fastened together a Y-shaped frame that fit perfectly over the back of his hand.

Next he gathered more aluminum, copper, and brass sheeting. He ordered steel wire usually used in model planes, carbon-fiber tubing for the arrow shafts, and a few cylinders of low-friction Teflon plastic. He cut out two pieces of flexible spring-steel to act as the bow and stretched the steel wire between them for the string. Using a lathe, he shaped pieces of brass for the arrowheads, glued them to the carbon-fiber tubes, cut a groove down the center of one of the Teflon bars, and placed it in the center of the crossbow. To fire, he pulls back the wire, hooks it around a brass block, and places an arrow in the groove. When he flicks the thumb trigger, the brass block drops, the wire pops forward, and the arrow flies.

Speaking of Blades for Dispatching Zombies...

Here is a site called Zombie Tools that carries various swords, fighting spears, machetes, and other bladed weapons for dispatching the undead.

How to Make An Assassin Arm Blade from "Assassin's Creed"

I came across this at MSNBC originally (story here). That in turn linked to a video:


By following another link, I found a site with instructions on how to make the mechanism. (Link here). As noted in the MSNBC story, this might not be legal to carry around, but it sure looks cool.

Gerber's Zombie Apocalypse Kit

Gerber, the well-known maker of knives, axes, multi-tools, etc., has come out with a selection of knives, axes, machetes, and so on, in its own carry-case, specifically for a zombie apocalypse. More here as well.

Kukri Knives

To survive the Zombie Apocalypse, you are going to have to kill zombies. To kill a zombie, you have to destroy the brain or the brain stem. This is probably best done using a firearm to shoot the zombie in the head--preferably from a safe distance. It goes without saying that it must be a clean head-shot. Shooting off a zombie's jaw isn't going to do much, except maybe make it harder for the zombie to chew on you.

Sometimes, however, you won't be able to shoot a zombie. Maybe you have run out of ammo. Maybe you have lost your gun, or can't get to it. Or maybe you don't want the sound of the shot to attract more zombies. These are situations that call for a hand-weapon.

In the Zombie Survival Guide, the author suggest a variety of different swords, machetes, and other bladed weapons. I certainly don't want to challenge the efficacy of particular weapons in the hands of an experienced warrior, but for most of us, there are problems with these weapons.

Machete: the standard machete has a long blade (generally around 20" on a typical model), but made of thinner metal. While great for hacking through grass or light undergrowth, the blade is too thin for serious zombie chopping, which will need something that will cut deeply into a skull or through a neck.

Sword: there are a great variety of swords out there, but lets face it, most are nothing but poor copies, made of cheap materials with inferior workmanship, and too heavy to boot. Compare a real sword to a "reproduction" and you will immediately notice that the real blades are generally much more narrow and lighter, and much better balanced. The real thing is a weapon, as opposed to a wall hanging. Even if you get hold of the real thing, most will be too long to be useful in the confined spaces of a building. Also, lets be honest here, using a real sword effectively takes a lot more skill and training than most of us have or will acquire.

What is needed is something of almost caveman simplicity--something that takes advantage of the natural and strong chopping motion of the arm, but is strong enough to take out a zombie. One weapon that satisfies this criteria is the kukri.


The Complete Encyclopedia of Arms and Weapons (Simon & Schuster: New York, 1979)  indicates that the kukri (or khukari) is:
The national knife and principle weapon of the Gurkhas of Nepal. Its form, especially the forward-angled blade, shows that it is closely related to the ancient Greek swords MACHAIRA and KOPIS, which almost certainly accompanied Alexander the Great to India. ...
The Encyclopedia of Handheld Weapons (Chrysalis Books: 2002) notes that the kukri is not only a superb weapon, but also "a highly effective field tool which is favoured by many experts besides the Gurkhas themselves for jungle survival use."
The kukri's weight and blade shape provide superb chopping, hacking and slashing performance. The heavy blade chops powerfully through logs and branches, and the reverse curve edge cuts deeply with little effort. The kukri is almost unmatched for heavy survival tasks such as shelter building and clearing vegetation and can also be used for surprisingly delicate work. It also excels as a close-combat weapon, where the power of its chopping stroke is legendary--tales abound of Gurkhas lopping off the heads of their enemies with a single stroke.
The Wikipedia article linked above also indicates that the kukri can be used effectively as a stabbing weapon. For someone with experience in fencing, the angle of the handle relative to the blade may make this seem awkward, but stabbing with the kukri may be more natural to someone with no preconditioning to thrusting in a particular fashion or style.

The particular model in the photo above has a 12 inch blade with a full tang. The blade is approximately 1/4 inch thick steel at the spine. The handle is covered with two wooden scales on each side fastened with brass steel rivets. The sheath is wood with a thin leather covering and (presumably) brass over the tip. The knife was made in India, and supposedly represents the government contract knife for the military.

The knife is solidly built. The knife tang actually stuck up a bit past the wooden scales, and really dug into my skin the first time I tried using it for chopping. I took a Dremel tool and sanded these down, which made it much more comfortable to use. The blade came unsharpened. I typically use a Lansky sharpener, but this was way more than it could handle. I ended up using a fine metal file, and finished it up with a stone.

As promised, the knife puts most of the weight of the blade toward the tip, making it natural to swing. I've tested it out on chopping wood, brush, and grass. It does not cut into thicker wood as well as an ax or hatchet, but would probably work. It does very well in cutting through brush. Surprisingly, I had trouble with chopping through grass and fibrous weeds, such as milk-weed. It would obviously break the stock, but it didn't cut through, which allows the grass and weeds to collect around the blade, which I had to pull off. This may be more of an issue with my sharpening or cutting technique, or perhaps because the blade is so thick.

While it would be a serious weapon, I think that a longer length would work better as both a weapon and as a field tool. In some of my reading, I had come across references to the kukri's used in WWI and earlier were longer--15" or more.

I ordered mine through Atlanta Cutlery, which has other models available. I would also note that kukris can be ordered through Amazon.com. Sarco sells various kukris, including 18" and 24" models.
