Abstract
A rotary electric shaver generally includes a handle assembly having a longitudinal axis, and a head assembly attached to the handle assembly. The head assembly includes a plurality of outer cutters and a plurality of inner cutters. Each of the inner cutters is paired with one of the outer cutters for cooperating to cut hair. The head assembly also includes a tray on which hair cut by a first one of the pairs of cooperating cutters is permitted to commingle with hair cut by a second one of the pairs of cooperating cutters. The head assembly further includes a fastener that extends longitudinally for attachment of the head assembly to the handle assembly such that the tray pivots relative to the handle assembly. The head assembly further includes a biasing element that circumscribes the fastener to bias the tray from a pivoted position into a non-pivoted position.
