Electric shavers with removable trimmer

Haircut knife (trimmer)

— the trimmer is a tool used for shaping facial hair and performing other supplementary tasks; refer to "built-in trimmer" for more information. The detachable clipper attachment holds advantages mainly due to its ability to be attached only when needed. This feature saves space on the shaver, positively impacting its weight and size. Moreover, removable trimmers are simpler to clean than built-in ones. In certain models, these attachments replace the main head and can be substantial and efficient, suitable for cutting both beard and head hair.
