Hey there I've been working on a this project on and off this summer. (mostly this fall)

As you can see it's A hidden blade, I started with a ,desk drawr slide ,some sheet metal (For the blade and part of the trigger mech) ,a few nuts and bolts ,and some thick steel wire. also a paper clip or 2 bent into some small springs.

I'll be building 1-2 more after i finnish this one i'll be making an instructable for those. This one's kinda the test dummy.
I've been trying to make a hookblade (without the blade) for ages, I would use it as a climbing hook for Parkour.. can someone give me some help?
<p>dude id love to help it seems pretty easy just do everything that the hidden blade has to have but then weld a peace of bent metal at the end </p>
<p>well you need the hook to be durable for the pulling and all that the actual thing will need to be able to withstand and hold human weight along with the fact that it would need to not fall off so it is pretty difficult to make the hidden hook blade thing :P</p>
well firstoff i would never parkour with this hidden blade on my hand letalone a hook blade. just cause in the game it can be used effectively doesn't mean it would be in real life tie something rigid on your arm tight enough to hang from next time you do parkour and see how it works out for you. why not make a hook that you can hold on to? and an extended reach isn't always something you want for parkour it would really hinder actually getting up onto a ledge.
Not really... nothing eve locks the blade forward at this point it's fun to pretend to stab yourself case the blade retracts right in.
ah. not so bad then
just don't try carving with it. that would be funny! :P
So does it retract without you having to push it in with your hand?
You must push it back in with your hand after releasing a forward locking mechanissam <br>
LOVE IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
you should do an instructable for the hookblade now :)
How do you build it???
thnx thid is awsome ive been trying to find this <br>
you guy are all retarts it not dangerous it cover his wrist so it will not get cut and it wont stab his palm because it only activated when he move his palm back der <br>
Herp drp! yup this is all true.
this looks kinda dangerous
Could you make a vid of it working?
All in good time.
What if you had your hand in the wrong place and you accidentally cut your wrist...
Then I'd have a cut wrist. Asif it'll ever happen. Cause if you look... the metal covers my wrist.
Looks cool man. =)
Indeed it does. :D
That's a cool workup! But, well, could you please put something under the blade to protect the palm of your hand? If the blade came out and impaled your palm (just proximal to the base of your middle finger), you'll sever the watershed area where the radial artery and ulnar artery connect. Hate to see someone bleedout while still in the R&amp;D phase;)<br><br>All joking aside, very dangerous! I had a patient die a couple years back from a laceration in this particular area- rare, but it does happen.
so far half of the tools I've used to make this are 2 times more dangerous than the knife itself.
It's fine it's not spring activated it's only gravity and the blade cannot come out unless my hand is clearly out of the way (by like 5 inches). I'm really not worried about stabbing myself in the slightest, at this point.
holy crap its out of metal thats crazy man
