A hand-held hair dressing device (10) has a blade (13) with a sharpened cutting edge. The blade is preferably V or U-shaped and permanently or removably supported by the limbs (12) of a Y-shaped body with an extending hand grip (11). The blade may be made from a single piece or from multiple segments with straight or curved cutting edges. The blade of blade segments may be fixed, such as by an adhesive, to a supporting carrier. Guard projections may extend from behind the cutting edge to beyond the cutting edge to reduce the likelihood of inadvertent contact with the blade edge while maintaining effective cutting action. In a method of use, the hair dressing device is manipulated so that the blade partly surrounds a cluster of hair strands and the device is moved to cut at least some of the strands of hair.
