OTF Karambit

Here is re-designed automatic karambit.
I finished it 5 month ago, but I didn't upload it because I thought it might bring me a trouble. and I am uploading it anyway now.

I organized file this time, so you should be able to print it with out much problem.

However, if you want to finish making it, you should get some parts, such as guitar string (or something similar) and an extension spring (specific kind of..)
Other than that, images should explain how to make it.
Good luck.

• If you happen to make it, please don't harm or threat anyone with it. I am not responsible for any incidents caused by it.
