Merkur’s 570 Progress Adjustable double edge razor is the first of a new pedigree of performance enhancing safety razors with adjustable heads. Turning the knob at the base of the handle creates either a narrower or wider gap between the blade and the safety bar. The blade position preferred can be noted by using the 1-5 scale around the bottom of the handle. The head of the Progress measures 1-5/8" long x 1" wide. The handle is 3-1/8" long x 7/16" diameter, and has a secure-grip rib design. Overall length of the Progress is 3-7/16", and it weighs approximately 3 ounces. The knob at the base of the handle of this two-piece razor with long-screw mounting is turned clockwise to unscrew the top plate for loading the blade. Comes packed in a sturdy plastic case (good for storage or travel) with a pack of 10 Merkur replacement blades. Uses any double edge blade. Boxed. $72.00
