The self-sharpening chrome-plated high carbon precision steel blade stays sharper for longer. Known as the balding fine tooth blade, it allows for surgically close cutting, ideal for Chiskop cuts and bald/skin fades. Ground Wahl blades offer a closer, finer precision cut, and regular oiling extends blade life. Specifically designed for full-size clippers, it's not meant for adjustable ones. Compatible with model 79111-1616.
