A device for treating a safety razor blade, including blades fixed between end portions of the safety razor blade, may include a polymer-based mat. The mat may include at least one substantially plane surface having an indentation hardness less than 50 measured on the Durometer Shore A scale. The mat may be coupled to a substantially rigid frame structure. The mat may sharpen and clean the blades when the safety razor blade is moved along the mat in a direction opposite to a normal shaving direction. The device may further include first and second sidewalls on first and second sides of the mat. The sidewalls may prevent the safety razor blade from sliding off the mat in a first direction when a user of the device is sliding the blades along the mat in a second direction perpendicular to the first direction.
