You need only two qualifications to own this nerd-gasmic Raygun. A love of Steampunk and some serious money to burn. The WETA Steampunk Raygun will cost you around $6,000. Dr Grordbort’s Rayguns are a line of 1:1 scale antique styled, limited edition(only 50 units), sci-fi hand weapon props. Above you can see “The Unnatural Selector”.

I’m not one to have weapons on display, but I’d proudly display this geektastic piece of eye-cady. See, this is what WETA is doing when they aren’t making big screen magic in Lord of the Rings. It’s made from metal, glass and rare Venusian Worm Oak. This my friends is some serious Steampunk. No really, this kicks the ass of every other Steampunk thing.

Check out this amazingly awesome rubber band gun based on the Konami PlayStation3 videogame Metal Gear Solid 4: Guns of the Patriots. The gun is of course made out of stainless steel and even includes a “precision laser pointer” to make sure you hit your target. The gun was designed by a Japanese fan who had a lot of time on his hands, rubber bands and mad skills with stainless steel. Is this heavy gun not a thing of beauty? Check out the video below to see it in action.

Whether you’re an off duty Ninja just staying out of the rain, or that guy from the Avengers, the Umbuster umbrella should keep you protected by giving you a pair of brass knuckles. Even though these aren’t brass. Instead you have a choice of wood or aluminum finish.

I’m not sure how easy it is to hit another guy with the bottom part of an umbrella while open though. Wouldn’t you hit yourself with the top part as you swung at your enemy? I would recommend this for little old ladies. They need to protect themselves, plus they just plain love hitting people with purses and stuff. You can get the Umbuster in October for about $330.

Obviously inspired by the flame throwing prowess of Pyro in the X-men, Everett Bradford designed a system that mounts on his wrist and propels fire when he moves his hand back. The flame is ignited through a fuel can at his waist.

It looks pretty awesome too and I bet he could impress Rogue and Storm enough to score, but it is potentially fatal should he spring a leak. You can tell that he is feeling the intense heat on his hand and cant run it too long. The combustion mechanism is complex and he has a second video for a detailed explanation, but I wouldn’t try this at home. Creating fake mutant powers could prove very dangerous. Cool, but dangerous.

Here’s the perfect watch for the time traveller. It will offer some protection will blending in with the American old west. If things get out of hand in the saloon, just make like you’re checking the time and fill somebody full of lead. That’s because the folks at time travel HQ have replaced the clock gears inside with a 3mm gun.

The hands don’t move, so just act like your watch is broken if anybody asks for the time. As far as the gun, it will most likely annoy rather then kill, but they’ll be so stunned that you shot them with your watch that you’ll be an instant badass and probably become the new sheriff.

Some things are just plain wrong and twisted. Like this knife. As soon as this WASP knife stabs you, it injects frozen gas into your guts that will expand and blow you up from the inside. It was originally designed to help hunters neutralize huge animals quickly, but it now turns out that humans could potentially be the animals neutralized.

British police are said to be on the lookout for this knife even though the website states that “the company does not condone killing of innocent creatures”. I think the moral of the story is this: If you see a knife run…If you see a knife with buttons, run like hell.

This thing has blood and carnage written all over it. It’s ideal for fixing up the house if you don’t mind everyone inside ending up dead as a doornail. It can send a 6-D nail through a 2 x 4 at 200 yards, and as it’s creator David Wiggins points out, you could literally sit in your lawn chair while building a fence.

Comes complete with a hundred-round magazine no less. No, this is no nail gun. This is a nail machine-gun. And I don’t ever want to work on a home improvement project with David Wiggins. Ever.

If you happen to see a guy or gal wearing a wrist knife like this and approaching you on a darkly lit street, you’re gonna wanna run like hell. I think it’s safe to say that this thing could probably gut you real fast.

What could be scarier then than this? The price. At under $40, any psycho stalker, or goth D & D misfit can afford one and take to the street. See, this kind of thing here is why we need Batman to be real. It’s just crazy. You can also get one in dragon or skull form.

Upgrading the bow and arrow aint no walk in the park. The thing is perfected already. It’s lethal, efficient, fairly portable too. It’s been around for awhile. Somehow, the folks over at Thinkgeek have managed to make the weapon even cooler. Messier too. The Bow and Mallow shooter at long last combines archery with marshmallows. Check out the video below to see it in action.

Man, if I were still a kid, I could think of about a hundred different ways to get in trouble with this thing. I would think it would be perfect for Mischief night. While others are soaping up windows and TP’ing houses, you and a few friends could do stuff like, I don’t know, completely cover cars in marshmallows and the like. Loads of fun.

Man, when I was a kid I had all kinds of mildly illegal fun with slingshots. These days, the slingshot seems to have been forgotten, which is a shame because it’s a good weapon. It was the weapon of choice for Dennis the Menace.

Until now that is. Like everything else, the slingshot has now had an upgrade. If I were a kid again, I’d definitely use one of these Ringshots. Instead of holding a Y-shaped weapon, this slingshot slips on your index finger and thumb. Not sure about pricing and availability, but I am sure it’s all kinds of evil fun.

It will make your guns sparkling clean though. This has Sarah Connor written all over it. If mankind’s future depends on protecting John Connor and forming a resistance against the cyborg threat, you are gonna want your equipment clean and thus less likely to malfunction.

It’s essentially a dishwasher for guns, making it quick and easy to clean them so you can get right back out there and kill stuff. Or whatever it is you do. It will clean up to 10 handguns or 4 long guns at the same time. Clean guns…That’s what will win against SkyNet, no matter how many Terminator’s they send your way.

Next time you go to grab your little Taser stunner out of your purse, think about this: what would even be more frightening to a potential mugger is a grandma wielding a Taser shotgun. That’s right - Taser has announced an extended range projectile to add to your Taser arsenal.

Taser is of course targeting law enforcement with its new eXtended Range Electronic Projectile (XREP). It will fit any standard 12-gauge shotgun and smack you down with “the same Neuro-Muscular Incapacitation (NMI) bio-effect as our handheld TASER X26, but can be delivered to a distance of up to 100 feet, combining blunt impact with field proven TASER NMI.” Each projectile will come pre-packaged in a shell compatible with 12-gauge shotguns and will be transparent so police known which type of ammo they are taking you down with.

We aren’t sure what shocks us more with this product announcement - the Taser itself or the fact it is outfitted in a leopard print. Either way you look at it Taser drew some attention at CES this week by unveiling this stylish (?) take on a way to zap your attacker. It is the latest addition to the company’s C2 line up of personal protection devices.

Taser also was showing off a holster for your C2 which doubles as a MP3 player with 1GB of memory. That’s right - you can stalk the streets at night, favorite rock song playing in your buds, as you zap bad guys all around town.

We just can’t help but smile every time we look at this picture. What looks like a scene out of Jackass, the WildSling is a giant, three-person slingshot (or waterbomb catapult as the company calls it). The design calls for two people standing a safe distance apart to hold the WildSling handles while a third person pulls back the business end of the huge slingshot and aims for launch.

You probably wouldn’t want to launch anything more dangerous than a water balloon, and 50 balloons come with this package. The company says it can launch a balloon as far as 300 feet but I’m sure other things could go farther.

The MAARS (Modular Advanced Armed Robotic System) robot is a 350 lb murder machine with upgraded weapon systems over its predecessor which was a modified anti-bomb robot retooled to carry armaments. Foster-Miller is the company responsible for the early system and the armament upgrades and their armed robot is the only one of its kind in Iraq, but its not firing a shot.

Safety concerns have prevented the killbots from being deployed in live combat, which prompted the development of this new death machine designed from the ground up as a combat robot and including several precautionary software implementations. The controller is now able to select fire and no fire zones, and a mechanical range fan is responsible for keeping the weapon aimed away from friendly positions. GPS programs installed in tanks and Humvees using battlefield mapping technology have proven successful in reducing friendly fire in Iraq, prompting the same technology for use with the new MAARS robot. Additionally a final precaution has been implemented to prevent the unit from being able to fire upon its controller’s location.
