yeah, lol, i guess i misunderstood. it was late. i thought you meant it was some kind of spring/lever assist knife. i started conversing with the guy that makes the sleeve gun, he want $295 for it. i asked him to describe it, and he said it operates on a rail and is powered by bungee cords. i just emailed him about building a custom device or at least drawing up plans on how i can fabricate it myself.
 
it seems to me that all you would need is a knife designed like this one

only large enough to add straps, and to modify the button so it's a pull ring or something similer. straped to the back of your forearm it would not be to bulky, and when you need it all you would need to do if bend your wrist FORWARD to grab the stratigicaly placed pull ring and out it comes over the back of your hand.
only real trouble i see is the force application involved in cutting or stabbing. it would have to be mounted very securly or it would twist and move. oh yeah and the fact that it would cost the arm you wanted to use it with and a leg as well...
 
thanks for the link, that's a cool knife, but as you said..very pricey. also the blade is a bit too short i think.
 
i guess i didn't get that across well. that particular knife is WAY to short, but i think that type of mechanisim is the way to go if your goal is over the hand blade presentation. also i would suggest that if you want something functional it's going to have to be a quality mechanism, hence expensive.
if you want a system to deliver a weapon to your hand thats a lot more logisticaly difficult.
 
not looking for something to deliver a knife to my hand, i could do that with the old rope trick. i want to make something that is securely mounted to your forearm, and will contain a blade that extends/retracts automatically. this is going to be for real world application, not a flimsy coversation piece.
 
then i would suggest looking for a VERY large out the front auto knife with aluminum handles or some other material than can be drilled and tapped. i think most of these use a leaf spring type device so you can get plans for such a mechanism and build your own if you want.
if you find one you can add straps as you desire to mount it on your for arm. better yet if you can find one with a slide switch insted of a button the the re-rigging of the trigger will be easy as well since you can pop the switch off and add a pull ring through the hole that's lible to be in the switch mount.
you should probably also think about adding ridged supports to connect the straps either on both sides of your wrist or opposite teh weapon itself . this should help prevent twisting when lateral force is applied in a cutting motion. however it won't do sh!t for stabbing. this will cause the rig to slide up your arm as there will be no back support. unless your willing to rig it around your thumb or something.
actualy it suddenly occurs to me that if you were to rivet the rig to a glove with a reinforced thumb strap you could minimize a lot of the twist and play that would result if it were just straped to your wrist.

now all you need to worry about is not stabbing through your sleeve when you deploy the thing.

keep this in mind though.
http://nicnac.net/en-us/dept_10.html the sandshark da here (never heard of them before) is 10.75 inches over all when open. the blade is only 4". you can probably double this but not much more.
 
hey, is this discussion still up? if it is i have GREAT NEWS for all of you. ill wait a day or two, if theres no reply ill put up a new discussion.

im already making an Armblade. yes. a hidden blade, finger triggered, boom! 14inch blade right outta your sweatshirt! so what do you think about that?
 
I think you better be very aware of what you are posting here to make sure it is not spam or illegal. :)
 
i am making the armblade!





hah, dude I’m a 14 year old kid. i haven’t even finished making the armblade yet, but don’t worry, I’m not spam and I’m not illegal because i don’t have a license to sell weapons, so i wont put up some kind of auction thing.

its good to see that people are still looking on this discussion, because i am making the armblade, but it will take a month for it to be finished. sounds ridiculous that a 14 year old kid would be able to make this rather than an older mind, but i can assure you that what i am making will be just what your looking for, and very functional since ill be making it out of carbonized cromolie (which will be very strong), and the frame containing the blade will be made of aluminum (very light).

don’t think that I’m some idiot kid that has no idea what he’s talking about, because i do, i make swords/ melee weapons as a hobbie. and I’m making all these weapons from my dads company shop- THE DRIVE SHAFT SHOP-. WE DO NOT DO ANY BLACK MARKET DEALS, SO DONT WORRY.

my weapon wont be so much as a stiletto, but more of a arm short sword. a 14inch blade that is hidden on your forearm, totally unseen and all you see on your arm is an aluminum steel frame, then, boom the blade comes jolting out, with built in auto lock, ready for any fight!

i don’t want to show specific details of how its made, because i do not want to be copied. that would infuriate me beyond any point of anger!:mad:


so tell me what you think? all of you. i will be sending pics once its done.
 
what do you mean by "what real world application would this have" do you mean wht uses? how real it is? youve confused me.


ill be on later tommorrow. see yah.
 
I want to see some pics of this. Sounds like a gigantic auto strapped to the arm.

Any mall ninja worth his salt needs one of those things!
 
Alright I tried reading through all the post with detail but nobody mentioned Deniro in "Taxi Driver". I havn't seen this movie in a while but I believe they showed him making the device to shoot out a pistol from his forearm. I think he made it out of curtain rods and other parts. Just another source for ideals i guess. I hope this is a "stay at home" item cuz I wouldn't want to imagine how you would explain this contraption a cop.

I will first say this: I am a very opinionated person, and I have a habit of voicing my opinions in a manner that often agitates people. I am also stubborn, and I have a low tolerance for stupidity and uselessness. I had intended to write an abrupt, condescending, and rather negative response to this thread in my normally arrogant style. Instead, however, I have decided that I will approach this particular subject with a degree of cautious sensitivity, and in a logical manner. Please bear in mind that everything I say should be taken with a grain of salt.

With that said, I must begin by stating my thoughts regarding the construction of the "forearm mounted stilleto knife" and the recently discussed automatic "arm blade." I personally believe that these devices are wholly useless in nature, being based almost entirely in fantasy. In my opinion, the idea of building such a contraption crosses the boundary from constructive creativity to fruitless absurdity. Nevertheless, I respect any individual's right to pursue whatever conceivable desire they may have, regardless of how ridiculous it may seem to me. I am not, in any way, attempting to infringe upon anyone's ability to construct or possess what they wish. To quote a well-known cliche: "It's a free country." I only ask that everyone, particularly nightkrawler and ArmBladeCreator, consider the implications of my next statements.


My concerns are as follows:

First, these forearm-mounted blades are fantasy weapons. They are not practical as a weapon or tool. They would necessarily be very delicate devices, and if not constructed with precision, they could potentially harm the user. It would likely be a hindrance if the user were required to perform certain tasks with the device strapped to the forearm, due in part to the sheer size and weight. Wearing such a contraption in public would require one to dress only in long-sleeved garments; this could become quite uncomfortable. These "arm blades" appear useful in movies only because the director is not forced to deal with such "real-life" considerations.

Second, I am concerned with the use of the term "weapon" and the phrase "ready for any fight!" If the motive for possession of such a device is to actually use it as a weapon, then I really must object. To attempt to use this "arm blade" as a weapon, even for defense, would be extremely dangerous. To have any blade, especially one 14" in length, attached to one's forearm would be many times more dangerous than to have a similar blade held in the hand. For example, if the need arose, it would be virtually impossible to remove the weapon with a single hand. Also, the design would need to be fool-proof, with integrated safety features to prevent an accidental activation of the mechanism. If the blade were to accidentaly discharge in close proximity to another individual, he or she might suffer life-threatening injuries as a result. Additionally, one must consider the consequences of using this device as a weapon. Under most circumstances, using such a weapon in a fight would be not be considered justifiable, even for defense. The law generally allows for the use of appropriate and proportionate lethal force when a person feels that his well-being has been threatened. Eviscerating an attacker with an arm-mounted "short sword" would most likely be considered an unnecessary and criminally negligent use of lethal force.

Third, one must consider the legal aspects of possessing such a device. If this "arm blade" utilizes a mechanism which automatically deploys the blade at the push of a button, it is therefore technically considered an "auto-knife." Automatic knives are illegal in many areas of the country; it is unlawful to manufacture, buy, sell, or simply possess these knives. Also, as the function of the device would necessitate a relatively long blade, the device would be in violation of certain blade-length laws. It is most certainly illegal in most areas of the country to carry a 14" blade that has no practical application other than as a weapon. Imagine the chaos that would result if a law enforcement officer discovered that a person was wearing this "arm blade." In today's society, people are becoming increasingly unfriendly toward knives. The sight of this arm-blade device, obviously intended as a weapon, would utterly terrify some people. How would the wearer of such a device respond to the question, "Hey... what's that on your arm?"

Finally, I find it unusual that there are almost no responses questioning the practicality of the proposed device. Many of the members of Bladeforums share a dislike for "mall ninja" types (mall ninjas are generally described as those people who are inclined to purchase inexpensive and poorly manufactured knives and weaponry with the belief that it makes them "cool" or "badass"). In fact, I have even been criticised, as I am sure others have, for my love of large fixed blades; the reasoning being that small knives are good enough for any possible cutting chore, and possessing anything large is considered "showing off." Given these facts, I would expect many forumites to be posting their objections to this "forearm-mounted blade" concept. I would have believed that the idea of an automatic short-sword strapped to a person's arm would have everyone here crying "Look out for the Mall Ninja!" Am I the only one here that believes this idea to be rather immature and slightly reckless?

There. I have said it, and have sealed my fate. Now will come the fuming criticisms and bitter remarks. For those of you who took the time to read this entire post: I'm sorry for wasting your time. For those of you who skipped over those last few paragraphs and decided to read this last part first: don't worry, you didn't miss anything important.

nightkrawler: If I have offended you with my remarks, then I apologise.

ArmBladeCreator: If I offended you, I really don't care. Frankly, I think you're full of bullsh*t. However, show me a completed, fully operational, and foolproof "arm blade," and I'll gladly eat my hat.

This will be my final post here until sometime after December 25th. I wish everyone a very Merry Christmas and a joyful holiday season. Peace, friends.

Ha! Beat me to it, I was just going to post that! What about Rosa Klebb's shoe knife in From Russia With Love?!

This discussion is over a year old. (For the benefit of anyone expecting nightkrawler to respond any time soon.)

This armblade sounds like fun. If nothing else, it's an exercise in creativity. Invention doesn't always go in a straight line, and until you make a model that works well, you won't know what other ideas it might inspire.

Obviously, it's not going to become a common household item. But you may have a career in fantasy movie props waiting for you. :D

oilman, yeah i thought about those, but they are actually police baton shaped daggers. you can see them up close in a few scenes. so i think he just has them hidden up there and slides them out in that scene. not actually attached to his arms.


Not wanting to fight about it in the first place but since it's been ressurected I would point out that the Freak in Hellboy had different swords in the beginning than he did for the rest of the movie. The first ones didn't have the sideways handle and did shoot out of his sleeves.

And the Preditors in AVP had some cool ones. They even extended and turned around when needed. So next time you see a Preditor you could ask how they did it.:D

Good luck on making a pair, I would be most concerned with getting a 3" wide hole in my hand when they accidentally fired though. YMMV.
