1. An assembly, comprising:
a shaving head, including: 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; and 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 being 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; and
a blade breaking component, including:
a first sloped guide surface having a first end and a second end and a second sloped guide surface having a first end and a second end, the first end of the first sloped guide surface and the first end of the second sloped guide surface forming an opening, the second end of the first sloped guide surface and the second end of the second sloped guide surface converging to form a channel below the second end of the first guide sloped surface and the second end of the second guide sloped surface, an angle formed by the first sloped guide surface and the second sloped guide surface being between 45 and 179 degrees, and
the channel having opposing parallel surfaces orthogonal to a plane defined by the opening, the channel being positioned off-center relative to a midpoint between the first end of the first sloped guide surface and the first end of the second sloped guide surface.
