We welded the two parts, the blade and the handle, together. Although this method doesn't allow for multi-color printing, it does make the overall production process much easier—all you need to do is print the two parts separately and then glue them together.

If anyone wants to own the entire knife, including the two halves of the blade and all the details, I will release a new revised design in the future.

This design was originally intended mainly for my own use, but I also thought that maybe other friends could benefit from it as well.
