Abstract
A safety razor for personal grooming is disclosed. The safety razor includes a handle, a cap, and a base plate that has blade-engaging surfaces that define the razor blade angle when clamped between the cap and the base plate. The base plate can be double-sided to provide a second angled blade-engaging surface that defines a second razor blade angle when the razor blade is clamped between the second side of the base plate and the cap. The modular base plate allows a shaver to replace or flip, in the case of double-sided base plates, the base plate in order to change the blade angle and the aggressiveness of the shave from the safety razor.
Claims14
A safety razor comprising:
- a handle;
- a cap having a central threaded stud to threadingly engage the handle;
- and
- a base plate defining a central aperture for receiving the central threaded stud therethrough, the base plate having a first side defining a first angled blade-engaging surface and a second side opposite the first side, the second side defining a second angled blade-engaging surface;
- the base plate configured for securing a double-edged safety razor blade when the base plate is positioned in a first position, or when the base plate is positioned in a second position;
- wherein in the first position, the safety razor blade is clamped between the cap and the first side of the base plate, the second side faces in a direction of the handle, and the first angled blade-engaging surface defines an angle of the safety razor blade;
- and
- in the second position, the safety razor blade is clamped between the cap and the second side of the base plate, the first side faces in the direction of the handle, and the second angled blade-engaging surface defines the angle of the safety razor blade;
- and wherein the first angled blade-engaging surface and the second angled blade-engaging surface each have separate surfaces on both sides of the central aperture to apply the first and second blade angle to each side of the safety razor blade.

A base plate for use in a modular safety razor, the base plate comprising:
- a first side defining a first angled blade-engaging surface;
- and
- a second side opposite the first side, the second side defining a second angled blade-engaging surface
- the base plate configured for securing a double-edged safety razor blade when the base plate is positioned in a first position, or when the base plate is positioned in a second position;
- wherein in the first position, the safety razor blade is clamped between a cap and the first side of the base plate, the second side faces in a direction away from the cap, and the first angled blade-engaging surface defines an angle of the safety razor blade;
- and
- in the second position, the safety razor blade is clamped between the cap and the second side of the base plate, the second side faces in the direction away from the cap, and the second angled blade-engaging surface defines the angle of the safety razor blade;
- and wherein the first angled blade-engaging surface and the second angled blade-engaging surface each have separate surfaces on both sides of the central aperture to apply the first and second blade angle to each side of the safety razor blade.

A modular safety razor shaving system, the system comprising:
- a handle;
- a cap having a central threaded stud to threadingly engage the handle;
- and
- two or more base plates, each base plate defining a central aperture for receiving the central threaded stud therethrough, each base plate having a first side defining a first angled blade-engaging surface that defines a first blade angle when a double-edged safety razor blade is clamped between the cap and the first side of the base plate;
- at least one of the two or more base plates being double-sided, the at least one double-sided base plate having a second side opposite the first side, the second side defining a second angled blade-engaging surface;
- the at least one double-sided base plate configured for securing the safety razor blade when the at least one double-sided base plate is positioned in a first position, or when the at least one double-sided base plate is positioned in a second position;
- wherein in the first position, the safety razor blade is clamped between the cap and the first side of the base plate, the second side faces in a direction of the handle, and the first angled blade-engaging surface defines the angle of the safety razor blade;
- and
- in the second position, the safety razor blade is clamped between the cap and the second side of the base plate, the first side faces in the direction of the handle, and the second angled blade-engaging surface defines the angle of the safety razor blade;
- and wherein the first angled blade-engaging surface and the second angled blade-engaging surface each have separate surfaces on both sides of the central aperture to apply the first and second blade angle to each side of the safety razor blade.
