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
