Clicky Foldable Karambit utility knife

I had old utility blades with no usage laying around until I found this awesome design.

I thought a few improvements could be made, so I changed the design a bit and added “grippy” features and “clicky” flexures.

You can find a video of me opening and closing the karambit package opener here: 

PRINT, BUILD AND USE AT YOUR OWN RISK.

This is very dangerous and you can easily cut yourself!!!"Extra materials:

4x M3 12mm bolts

1x M3 8mm bolt

5x M3 nuts (low profile is better for me but its up to you at the end)

8 x washers" - Oki
