A razor cartridge assembly comprising:

• a plurality of razor blades, each razor blade having a cutting edge;
• a blade housing configured to accommodate the plurality of razor blades;
• at least one support member disposed in a frame of the blade housing comprising a front portion, a rear portion opposite the front portion, and two side portions connecting the front portion and the rear portion;
• a plurality of seating protrusions disposed on the at least one support member;
• and
• a connector coupled to the blade housing at a bottom side of the blade housing and configured to be detachable from a razor handle,
• wherein:
• the at least one support member is extended in a direction transverse to the cutting edges of the plurality of razor blades between the front portion and the rear portion of the frame of the blade housing such that the front portion and the rear portion of the frame of the blade housing are connected by the at least one support member disposed between the front portion and the rear portion of the frame of the blade housing;
• the plurality of seating protrusions are configured to seat the plurality of razor blades;
• the plurality of seating protrusions are spaced apart from each other;
• the plurality of seating protrusions include a first seating protrusion having a first height and a second seating protrusion having a second height lower than the first height;
• the first and second seating protrusions protrude from a same surface of the at least one support member such that a base of the first seating protrusion and a base of the second seating protrusion have a same baseline that is parallel to a bottom surface of the at least one support member exposed at the bottom side of the blade housing;
• the first height corresponds to a length between the baseline and a distal end of the first seating protrusion;
• the second height corresponds to a length between the baseline and a distal end of the second seating protrusion;
• and
• the cutting edge of the razor blade, which is inserted into a seating slot formed between the first seating protrusion and the second seating protrusion, extends past the distal ends of the first and second seating protrusions.
