This invention relates to a novel application of liquid-infused surface materials (LISM) to at least a portion of one or more surfaces of razor components (e.g., frame, housing, clips, blade supports, blade body, blade edge, lubricating bodies, guard, handle, grip, button). If applied to a skin contacting surface of a component, the one or more LISM layers may generally be abrasion-resistant, long-lasting or non-erodible, desirably elevating shaving performance, such as glide, comfort, rinsing, and cleanliness, while also simplifying the manufacturing process.

An adapter for coupling each of a razor handle and a razor cartridge together is provided. The adapter includes a cartridge engaging portion and a handle engaging portion. The handle engaging portion comprises at least one wall that defines a receptacle for receiving a razor handle and at least one handle protrusion extending from the at least one wall and configured to engage a central recess of a razor handle. The cartridge engaging portion is coupled with the handle engaging portion. The cartridge engaging portion comprises a stem that defines a first recess and a second recess for selectively engaging a first cartridge protrusion and a second cartridge protrusion and a tongue member slidably coupled with the stem and configured to contact a cartridge.

A shaving head that doubles as breaking mechanism to break a safety razor blade into two pieces to form a 2-blade shaving razor. The shaving head includes a front component having a retention guide, a first position stop and a second position stop at a distance offset from the first position stop. The shaving head further includes a back component having a blade slot configured to receive a first blade portion and a second blade portion formed from breaking a double-edge safety razor blade such that the first blade portion has a different width compared to the second blade portion. The retention guide is configured to retain the first blade portion and the second blade portion in the blade slot responsive to the retention guide being at least partially inserted into the blade slot. The sharp shaving edges once installed form a shaving angle between 5 and 30 degrees, where the shaving angle is determined by where the blade is broken.
