Review on Uproot Lint Cleaner Pro Pet Hair: Portable Lint Remover for Carpet & Upholstery, Lint Scraper Roller for Dog Hair, No More Lint Tool with 2-Pack by Ken Hamdan

Works like an absolute magic on rough/non-fragile fabrics such as cat litter and bedding (including synthetic litter), cat stools, carpets, jeans, fashion t-shirts, etc. It is however part of the threads of a long brass machine screw, cut in half and channeled to allow it to be attached to the triangular head of the instrument. The grooved sides (arrow) are unpolished/deburred and will snag, roll and snap the threads of finer fabrics.
