## Abstract

A shaving razor handle includes a handle casing, a handle interconnect member coupled to the handle casing, the handle interconnect member having a body, a projection extending from the body, the projection having an enlarged distal end and angled side surfaces extending from the distal end to a base, wherein the side surfaces taper from the distal end to the base, forming a projected apex angle of about 45 and 60 degrees. The projected apex angle is about 52 degrees. The body has an arched profile. The body is asymmetrically shaped or generally D-shaped. The body has two slots that extend through the body on opposite sides of the projection. The handle includes a spring-biased release button having a pair of pusher arms, wherein each slot receives a respective pusher arm. The handle includes a plunger extending through an opening defined by the body and extending through the projection.

## Claims
