altair hidden blade

Here atlast my hidden blade system... Sorry it took a long time for me to upload, but the last few weeks I was quite bizzy. As you can see I used as menny people an drawer slide rail. I used two for my idee, becose to me if I used one the blade woulden'd come out to far... I atached it to echother as you can see. The knife I used looks like a real knife but its just an paper-knife so it isn´t realy sharp (only the tip) There is also an lock on my system, if the blade slides in, the metal poke will flip into the lock, so the blade stays hidden. Also at the and of the blade I used tie rips the stop the blade when its at full length, (it only stops the blade, not the lower drawer slide rail) And as you can i also can attached it to my arm with band´s (I also have that done, I will upload that to in the future) In the d-tails I hope you can see how I made it, Cose im quite bad in explaning. (in english that is)


the two drawer slide rail´s are 21,5 cm long, 2,5 cm width and 0,8 cm high. The paper-knife has a total lengt of 19 cm and the blade is only 9 cm. the paper-knife is in the drawer rail atached. The blade is at full length 46,5 cm

Want to see it in action? Here is a short video of me demonstrating it: [link]

More is coming, but I don't have all the time for DA so it will take some time...
