The Andis UltraEdge size 3 1/2 is a detachable clipper blade for leaving a consistent 3/8 inch (9.5 mm) of hair. It suits length-setting and graduation work where more hair should remain after clipping. For barbers working through several lengths in one haircut, this blade provides a defined longer setting within a detachable-blade kit.

High-carbon steel supports the cutting edge through repeated use, while a chrome coating helps protect against rust and corrosion. The removable assembly can be taken off for cleaning, maintenance or a change to another blade size. That makes it practical to move between sections of a cut without changing the clipper itself.

Andis lists item 563873 for AG, AGC, BG, DBLC, FHC, MBG, RDLC and SMC models; its package also names Oster A5 and 76 compatibility.

Brush hair out of the cutting area and maintain regular disinfection. Oil the blade between cuts as Andis recommends, and wipe away the excess.
