The Viking utility knife (also found very similar knifes while looking for reference, called "Blacksmith knife", couldn't find if it's a different kind of knife) is forged all in one piece, and the portion that would be use as a handle is twisted for a better grip.
Really liked how it looks and the idea of knife made of one single piece of iron, so i decided to model it and i like how it ended up.
Modeled in Maya and textures generated in Substance Painter.
