Parker Safety Razors offers quality double edge safety razors in three styles: Butterfly-open, three-piece and two-piece adjustable. Reminiscent of vintage designs, butterfly razors have hinged plates that open to allow convenient access to the blade. Three-piece razors disassemble into three separate pieces for easy cleaning. This style dates back to the early 1900s, but Parker has enhanced the design with modern materials and etchings that set the brand apart from others on the market today. Parker's newest style, Adjustable safety razors are designed to enable the blade angle to be adjusted by turning the knob on the bottom of the razor, so that the exposure can be set to each individual’s preference.
