If you’re referring to the wavy pattern along the cutting edge, that’s not from the folding process. The hamon is added to the blade during the quenching process, by adding clay to the steel. The clay causes the covered steel to heat differently than the uncovered steel. That differential heating is what is visible as the hamon.
It’s largely decorative, but does have function as it determines what part of the blade can be sharpened to an edge.
Job postings like yours are extremely common when the applicant has been pre-selected but the company still requires an external posting. Your applicant likes off-grid hiking, is a hobbyist drone pilot, and enjoys grilling?
Now the job posting for a IT position requires an applicant who is capable of accurate pathfinding using a paper map and compass, two years of drone pilot experience, and four years of culinary experience.
