The Andis Size 0A UltraEdge blade is a detachable cutting head for short haircutting and blending. It leaves a nominal 1.2 mm, or 3/64 inch, making it a defined length option for a barber building a graduated cut with interchangeable blades.

Part 64210 uses high-carbon steel with a chrome finish. The steel supports the cutting edge, while the finish helps resist rust during regular use. Its precision-ground teeth are designed to feed hair through the cutting head, and the snap-on fitting lets the operator change blades as the work calls for another length.

The verified fit includes Andis AG, AGC, BG, DBLC, FHC, MBG and SMC clippers. The size and 1.2 mm marking on the blade help identify it in a collection of cutting heads. Brush away hair and keep the blade clean and lubricated between cuts, following the clipper's fitting instructions.
