Design & Discussion of Mechanics for Wrist Blades, Knives, Wrist Spikes, Mini Flamethrowers, Stun Gloves, Arm Swords, Retractable Claws, and Exotic Gear & Equipment
Xiphoid, also known as a Retractable Forearm Dagger, is a class of bladed weapons with a dagger like blade that is retractable into a forearm worn wristband or bracer sheath.Designed for swift and quick surprise attacks. It is notable for being evolved from the Katar and similarities to the Pata, short punching swords, which results in the blade sitting above the user's knuckles.

After so much searching I finally found something that we can play with.
I went internet digging and I found a forum for people who make their own Predator costumes and props.
As most of us know, Predators are a alien race of hunters who wear large automatic forearm gauntlet blades.
So I searched through all their forum for a few hours and dug up everything I could on how they make thier wrist blades.
Some are simple with rubberbands or such to move the blade.
but then I found guys who make motorized claws...http://www.dragonskinstudio.com
O.K.....these are a little bulky, but they were made to fit into the big Predator gauntlets. I e-mailed one of the guys and for about $400 he said he could make it any size. I also asked about Wolverine claws and he said he didn't think it would be a problem to adapt them for Wovie claws.
So...yet another thing to add to my list to buy. Hmmmmmm .......I wonder how much of this I can write off on my taxes as 'product research' for my company????

wow thats pretty amazing but theyre kinda unneccecarily fragile looking i want one that a freakina lien can stomp on and itll still work!
Anyone who puts this much time into a full costume want to show it off. The most common if not the only place is going to be a convention or a costumed event. Most all of these events have to have safety security measures because people have crazy weapons and at some alcohol is served. From what I see online most places have a rule about no 'live blades' ...no metal blades. Any form of weapond that has ANY kind of blade or point must be made out of plastic, wood, or foam. No sharp edges or hard points. Many of these guys will go and build a Predator costume 99% real but beacuse of that rule they have to have 'toy' blades. I can't argue the point. Safe is safe, if you want real ones that is fine, just keep 'em at home.
I've been gettting swamped with PM and I try to answer them all. Someone asked me about Motors and arm blades and I said Pred claws. I went to the Hunters Lair and scaned their files as best I could. Got some pics, but no real schematics or instuctions. I did find this...
And the fellow lives in the same state as I do, not sure how far. I emailed him, we'll so if I can get all the info on these devices.
I'm probally making it harder than it is..I probally need to just go down to the hobby store and get a motor, gear, chain, forward/back switch, on/off switch, and a few other goodies to make it work. I have a few motors and gear box. Putting in a on/off is easy. Attaching a gear and chain is easy. How about the reverse? I don't think I've done that yet. Is there a easy way to reverse to motor to change the direction of the gear/chain

GAH, as much as I love mechanical stuff, that motorized blade is SCHWEET!!!
Hey Sinza, Most hobby motors are bidirectional, IE, if you reverse the current, it moves backwards. I's prbably just wire a three way toggle switch in parallel, with reverse polarities at either end of the switch... That way you dont have to mechanically put the syetem in reverse. That ought to do the trick...

By just looking at the design, it looks like it runs on a motorized rack and pinion system. I don't have a lot of money to pay 400 bones for a kit though. So I'm currently in search mode for similar parts. I'm thinking of using a smaller motor with gear reductions to increase the motor's torque. Which would fit better under a coat sleeve. Two items that I've been having trouble looking for are a custom pinion gear to fit unto the motor, also for a compatible rack.
Oh yeah, I'm also in need of a good small switch, in my prototype (which I took apart) I had to use a DPDT switch used for cars, but that's a bit bulky to carry around. Does anybody know where I can get similar finger switches like in the picture above that SINZA posted?

One of our veteran members made this suggestion for finding gears:

1. you get a boston gear catalog, or maybe there is one online. you look up rack and pinion gears, ( I don't think they are called linear gears, there are linear motors,) but you don't buy from boston gear, once you've Identified the pitch diameter you need, you look in a McMaster Carr catalog, or Grangers catalog.

LOL no need to yell... And it should only lag the first time you load it... Everything should go back to normal after that...

The Ki'cti-pa is the weapon chosen for most Yautja. Twin blades, double-edged, and sharp enough to tear through bone, these retractable blades are effective against large and small opponents. Using it shows the Yuatja pride, because they must fight face-to-face. They are the recommended first weapons because of their effectiveness. The barbs on the back are typically used against unarmored foes, and the weapon can be used to parry/trap other blades. Length is 6 to 18 inches. Width is the blades can be spread from two to eight inches apart.
Acid-resistant claws are almost identical to normal Wrist blades. In fact, the housing is the same. These new blades are only an inch longer, and are immune to all forms of damage including alien acid. The blades are virtually indestructible. The damage is only slightly more though. Those who have fought for many battles usually have made this simple upgrade. ...................................................................... Wrist blades
Predator Wrist blades, normal and extended modeThe Wrist Blade is the weapon of choice for most Predators and their iconic symbol. Twin or triple blades with jagged double edges are effective against prey. Using the Wrist Blades shows pride because Predators prefer melee combat.
The blades range from 12 to 18 inches long and retract from a wristband. They are forged from an unknown alloy which is almost unbreakable, but not totally immune to Xenomorph blood. In the first Predator film, the Predator uses lasers to heat the blades for more powerful blows. How they are sharpened is not shown.
In the computer game Aliens Versus Predator 2, a scientist's medical report of a Predator indicates that the Wrist Blades' wristband was grafted to the Predator's arm and removing it caused pulmonary arrest in the Predator being studied. The researcher speculates that the cardiac arrest may be an anti-tampering mechanism and comments, "What kind of society would rather have its warriors die than be disarmed?" However in Alien vs. Predator a Predator removes his wrist bomb, though his wristband was still attached to his arm. It should be noted that the film appears to ignore all of the background information established in the numerous AvP games, novels, and comics up to that point. This may explain the numerous differences between the two depictions.
In Alien vs. Predator, Scar has a variation with firing blades, when the slide on top is pulled back, the weapon arms. It fires the blades by extending the arm completely.
In Aliens vs. Predator: Requiem Wolf's Acid-resistant claws are almost identical to normal Wrist blades. In fact, the housing is the same. These new blades are only an inch longer, and are immune to all forms of damage including alien acid.
In Alien vs. Predator, the wrist blade used by the predator "Gill", named after the markings on his mask, was reversed so that the sharper end could be used more effectively in an outward swing that he used against a Xenomorph, which ended up in his wrist blades being melted in half by the Xenomorphs acidic blood.
:ghr:

You know the one thing I never understood about the yautja, was why any of them used non-acid resistant blades at all. I can understand the challenge of hand to hand combat with a very lethal prey, but they don't seem like the type to go into battle with worthless weapons. In every movie, in which they appeared, the shurikens have always been acid resistant, and they would be considered a secondary weapon. And yet, in many cases, their primary and most honorable weapon, their arm claws, are not built to withstand combat with their most common foe?
Perhaps I am, giving the writers more credit than they are due, but it makes not sense to me...

mmmm i think theres somewhere on the web, or on the dvd and they show you the blades and how they did them, if someone was good enough to have a watch and look on that then should be easy to find and do. if you ask nicely ill do a screen dump of a few things for yas. oh and hey im new woooo
I had an idea for these wrist blades for a while now: I was thinking of a co2 powerd one, as in use a car hood shock but modify the shock so that co2 is used to drive the shock out and have a automatic locking mechanism when the blade slides out it locks into place. To drive the blade back in its housing, have it spring loaded (heavy duty springs) so you can have 2 levers . 1st lever would be for the co2 cartridge (probably a trigger mechanism off one of those co2 bb guns). 2nd lever would disengage the locking mechanism that holds the blades out. so when you hit the second lever those heavy duty springs would would drive the blades back into its housing. i might build one when i get laid off for the winter.

I have been working on a predator style wrist blade and i have a few questions about it that i need to be answered. Such as is the blade part way out when its at rest or is it all the way inside the gauntlet. and where is the best place i can get eather metal or plastic versions of the blades. heres a video of what i have so far.
The blades are just chrome duct tape over cardboard at the moment, and this is with the blade being all the way behind the wrist while at rest.

Awsome Clyde
Well done.
As for blades....either make your own or go to the 'Hunter's Lair' web forum. Those guys make Predator outfits and may have some blades or might make you a pair. A Dremel tool and some cutoff wheels and you can make your own.
Or go to HomeDepot and buy a hacksaw and some aluminum 1/8th inch stock.
Or find a knifemaker who will make them for you......but expect to pay for the persons time and effort...won't be cheap.

Here,s some of my gaunts, i make lots more versions also
First Off, I want to apologize for the lack of updates regarding the slide system I've been working on and talked briefly about in an earlier post on this topic.
In short it's a automated slide system which any number of objects (blades, guns, and even smaller non weapons like zippo lighters, pens, etc.) can be mounted on it which then can be "fed" into your hand and then retract up your sleeve with a combination of a pulley system and heavy duty retractable key chain.
It's been very "touch and go" designing it and making it work. My first (non-automated) prototype which is a simple design that relies on the retraction unlike most that rely mainly on the projection. It works by creating momentum with a small fishing weight on the mounting plate and swinging your arm out and before it retracts you grab the end, after which you simply let go and it retracts up your arm.
Anyways, I've been adding a pulley like system to that and I'm designing to be run by a small powerful geared motor. What I need now is to wire up and attach a switch to control the movement of the motor (Reverse and Forward) I've tried a momentary DPDT switch but the only ones I can find are made for a car and other smaller ones (the ones I need) aren't momentary. So I'm hoping someone can tell me how I can wire up two small switches like on the Automatic Predator Blades from Dragon Skin Studio.
