Westcott® Titanium Bonded Non-Stick blades are six times longer lasting than the previous formula. Westcott® uses a process that bonds titanium to the blades and then coats them with a breakthrough non-stick formula to produce an adhesive-resistant, easy-to-clean, and longer-lasting cutting edge. Westcott also offers a wide range of anti-microbial protected products that inhibit the growth of bacterial odors. This technology keeps products from degrading by preventing the growth of microorganisms. It's ideal for products that are shared around the home, office or school.
