These plastic-free safety razors get rave reviews for close, comfortable, eco-friendly shaves. The Leaf has a pivoting head that allows for up to 3 blades. The smaller Twig has the traditional rigid safety head with a single blade and is good for precision shaves. A small magnet makes loading blades safer. Leaf makes specialized single-edged razor blades, but they can also use any double-edged safety razor blade by snapping them in half (see video online).
