An integrally formed rigid razor blade made of martensitic stainless steel includes a cutting edge portion, a base portion, and a bent portion. The cutting edge portion extends along a cutting edge portion axis and has a cutting edge at one end. The base portion extends along a base portion axis. The bent portion is intermediate the cutting edge portion and the base portion. The blade has a concave face and an opposed convex face. An average radius of curvature of the concave face of the bent portion is between 0.5 millimeters to 0.57 millimeters.

An intelligent shaving system is disclosed herein including a system having a handle, at least one blade connected to the handle, a microcontroller attached to the handle, a wireless communication unit configured to send and receive data from microcontroller to an external device, a memory configured to store data applicable to the at least one blade, and one or more sensors configured to send sensory data from the one or more sensors to microcontroller. The one of the one or more sensors is a proximity sensor or a camera having image sensor configured to capture video and/or still images. The shaving system assists in determining blade attrition and provides indicators to assist in shaving techniques. The shaving system further may include at least one blade slightly curved to follow a tangent of the skin. The at least one blade may have a nanolattice structure.
