Drawing on the Apple-style restraint design language, this reciprocating razor is centered on simple geometry. The whole machine adopts neat and square body block, uses matte aluminum alloy to shape delicate silver texture, and uses small area metal color ring to do hierarchical division, thus rejecting redundant decoration. The integrated black window realizes the pure impression of the rest screen, the dot matrix digital screen clearly presents the power and status information, and the visual level follows the human eye movement line when holding. Under the tough and simple shell, taking into account the real use scenes such as modular cutter head, water washing, holding counterweight, etc., the functional requirements are converged into a clean form, so that less is more.
