The Oster T-Finisher is a corded T-blade trimmer for barbers and stylists completing the detail work around a haircut. It is designed for outlining around the ears, tidying sideburns and defining the neckline, with additional applications in beard and mustache grooming. The T-shaped cutting head gives this tool its distinctive finishing format.

For services that include creative hair designs, Oster also identifies the T-Finisher as a tool for creating patterns in the hair. That makes it useful at the finishing stage when the work moves from the overall haircut to the edges and smaller details that shape its appearance.

A Whisper Quiet pivot motor powers the cutting assembly. The trimmer operates from AC power through an 8-foot cord, providing reach from the electrical outlet to the working area. Oster specifies a break-resistant housing for the body. Published product dimensions are 6.3 inches long, 1.5 inches wide and 1.4 inches high, with a product weight of 0.85 pound, giving a practical reference for its size in a workstation or tool kit.

The set includes the T-Finisher trimmer, T-blade 76913-586, lubricating oil and a cleaning brush. The supplied care accessories support the routine maintenance the cutting assembly needs between uses. After each service, remove hair from the blade and apply blade lubricant as Oster directs. Keep the blade number with the trimmer's model information when selecting a future replacement so the correct cutting assembly can be matched to the tool.

Its combination of a T-blade, pivot motor and corded operation suits a dedicated finishing position in a barber or salon setup.
