Wahl’s most popular trimmer, the Wahl Detailer Trimmer has been specifically designed for edge lining and detailing work. Designed with a extra wide T shaped blade that adjusts to zero overlap allowing you to cut closer to the skin. This is the ideal hair trimmer to create patterned designs, shape ups and beard lines. This corded trimmer can be used continuously as you will never run out of power, particularly useful if you need to use it for an extended period of time.
