Slit blade block and electric razor having slit blade block

A slit blade block of an electric razor, the slit blade block comprising:

• a slit outer blade including a plurality of outer blade pieces;
• a slit inner blade including a plurality of inner blade pieces, wherein when the slit inner blade, which is accommodated in the slit outer blade, moves relative to the slit outer blade, the outer blade pieces and the inner blade pieces cut hair;
• and
• a comb component including a plurality of comb teeth adjacent to the outer blade pieces, wherein:
• each outer blade piece includes
• a basal surface opposed to the slit inner blade, and
• a distal surface located at a side opposite to the basal surface,
• each of the comb teeth includes
• a distal surface, and
• a projection that projects in a direction parting from the outer blade pieces, each projection includes a peak, which is an outermost end in the parting direction,
• the comb component includes a corner at a side opposite to the peak, the corner forming at least part of an upper opening of the comb component,
• the slit outer blade is received in the upper opening of the comb component,
• the distal surface of each projection and the corner are located between the distal surface and the basal surface of an adjacent one of the outer blade pieces,
• the distal surface of each of the comb teeth and the distal surface of the adjacent one of the outer blade pieces are flat surfaces substantially parallel to each other and form a height difference therebetween, and
• a dimension in a heightwise direction defined by the peak of each projection and the distal surface of the projection is less than or equal to a thickness of each outer blade piece defined by the distal surface and the basal surface of the outer blade piece.
