Introduction: Retractable Hidden Arm Blades

Buy 2 equal sliding drawer mechnisms at any local harware store

a Package of Gorilla Glue Expoxy-Resin Tube.

2 pieces of 18 guage metal that can fit on the end of the sliding arm.


THIS WAS A PROP MADE FOR A karl ruprecht kroenen FROM HELLBOY 1 SO PLZ STOP BARKING AT ME SAYING I RIPPED OFF ANOTER PAGE.  SO STOP AND LEAVE ME ALONE THIS IS JUST FOR THE CONTEST!!!!!!!!!!

Step 1: Prepare the Mechanisms

to avoide cutting yourself when you place the blades on your amr it would be good to use a bench grinder or a metal file and grind down all points on the drawer slide. This way you don't cut yourself and its comfortable for you to move around with ease. Make sure you wear eye protection as well

Step 2: Cut the Metal "blade Parts"

For the blade looking part bend 2 corners to form a point and shave off the edges.

Step 3: Glue to the Slide Arm

Line the parts up on to each other clamp them togther and make sure they can stil move when the blade is glued to the slide arm.
Next mix up the Gorilla Glue Epoxy togther make sure you read the directions be careful its very sticky.

Spread an even coat on to the back of the blade the part you plan to glue to the arm. Line it up on the slide arm (Repeat Process) and then clamp it down and let sit for a few hours. For best Results let sit overnight.

There you have it you just made your very own set  of Retractable hidden Arm Blades. ENJOY!!

If you have any qestions about it let me know!!!

    They sell them at Homedepot they are very cheap. It only costed about $10 and they are stainless steel. If you can't find them there Im sure Lows has it or Ace Hardware. Let me know you need any more help. ^___^

    Thank you but these are for when he is in his SS uniform in the begining of the movie I have not made a tutorial on the 2nd style of blades he uses later on in the movie.

    If anything, THEY all ripped off the movie "Taxi Driver". In the movie, Travis Bickle used the same drawer device to throw a gun in his hand from up his sleeve.

    Thanks for your Instructable. Does the hat hint at you using this for a Cosplay event?

    PS., *cost

    I recreated the taxi driver effect, that actually locks in place. This instructable lacks.

    Blashfmay This one does not lack this one DOES LOCK!!!

    Not from what I see in the instructable it is just a drawer slide, it's not even cut down, to fit well on the arm..

    It worked perfectly on my arm for MetroCon.

    I can bolt on different things, knives, gun, claws onto this, for different effects. :) It also locks into place. :P http://www.youtube.com/watch?v=fp7hbsCNdUo

    No problem gald to be of some help. Yes the hat was for one of my many cosplay's karl ruprecht kroenen the Nazi Assassin from HellBoy 1. It came out pretty well!!!
