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!!!

1x M3 8mm bolt

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