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!!!
