I tried to make it so you could build from the pictures. Leave a comment if you do decide to build

Very cool! Does it spring out with rubber bands, or is it just a manual hidden blade? I'm not trying to spam, but you should take a look at my very latest hidden blade for ideas.

ya, i started off trying to build yours but i couldnt, so i made my own. you swing your arm to slide it out and then it locks.
Don't worry, I'm in the process for making instructions for it.
