Origami artist Juho Könkkölä spent 50 hours folding an origami samurai from a single square sheet of paper, with no cutting or ripping used in the process. He describes his process on Reddit:
Folded from a single square sheet of 95cm x 95cm Wenzhou rice paper without any cutting. The finished size of the work is 28cm x 16cm x 19cm. Only dry and wet folding techniques were used to fold the model. It took 2 months to design and 1 month to fold, although I was working on few other projects during that time too.

It took some effort and experimentation to fold the texture for the armor, while trying to simplify it to be somewhat manageable to fold. I folded 4 rough test attempts in total, and all of them took 3 days to fold each. There are several hundreds of steps to fold it from the square and there are probably thousands of individual folds. The asymmetry in the design allowed me to include sword on only one arm, while being able to make the character look symmetric.
