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
