The video shows the removal of a large wooden splinter that had embedded itself deeply under my thumbnail. To access and extract it, I had to carefully trim and grind away part of the nail using a small rotary (Dremel) tool over the course of about three hours. The footage captures this oddly satisfying and slightly gruesome DIY first-aid process.
