This karambit is a leap in complexity and accuracy as well as in aesthetic compared to the original design.

There are two print files, one for the full tang blade and another for the handle that is attached on both sides.
To join the handles to the blade you can use the available holes in both parts, or do what I did and just super glue it together.

I suggest printing the blade and handle in different colours to maximise the customisation available.
