New design with a pure copper blade that stays sharp, rust-free, and durable for easy removal of fluff and hairballs. The stainless steel support frame prevents deformation during use. Ergonomic design with an indestructible wooden handle, polished rounded corners, and a comfortable grip. The handle shape follows ergonomic principles for easy holding. Angle guidance: less than 10 degrees for finer surfaces and smaller hair balls; 30 to 45 degrees for rough surfaces and larger hair balls. Cutter head is 5.12 inches wide, providing a large removal area to save time and effort. It easily removes cashmere balls from cashmere coats and is also effective on carpets to loosen dirt; follow up with a vacuum for best results.
