Abstract

A shear-head for a dryshaver has a cupped frame in the interior space of which the cutter blade or blades of the dryshaver become located when the shear-head is connected to the dryshaver housing. An opening of the frame is spanned by an arcuately bowed, flexible apertured shear foil through which beard stubble extends into contact with the cutter blade or blades. Inner surfaces of the frame are provided with recesses in which mounting plates are lodged. These mounting plates have projections that are engageable with edge portions of the shear foil to hold the latter detachably on the frame.
