a cartridge body, comprising:
a deck comprising an inner deck portion, an intermediate deck portion, and an outer deck portion on a first side of the cartridge body, wherein said intermediate deck portion is laterally outboard of said inner deck portion, and wherein said outer deck portion is laterally outboard of said intermediate deck portion;
a plurality of staple cavities comprising an inner staple cavity defined in said inner deck portion, an intermediate staple cavity defined in said intermediate deck portion, and an outer staple cavity defined in said outer deck portion, and wherein each staple cavity of said plurality of staple cavities comprises an opening in said deck defining a cavity perimeter and a pair of endwalls;
a pair of projections extending from said deck, wherein each projection of said pair of projections abuts said cavity perimeter of only said intermediate staple cavity, and wherein each projection of said pair of projections comprises:
a cuff portion comprising a cuff interior surface seamlessly extending from one endwall of said pair of endwalls, a cuff exterior surface opposite said cuff interior surface, and a lateral cuff width defined by said cuff exterior surface;
a first transition portion sloping downwardly from a first end of said cuff portion to said intermediate deck portion, wherein said first transition portion comprises a first transition exterior surface; and
a second transition portion sloping downwardly from a second end of said cuff portion to said intermediate deck portion, wherein said second transition portion comprises a second transition exterior surface, wherein a lateral transition width is defined between said first transition exterior surface and said second transition exterior surface, and wherein said lateral transition width is wider than said lateral cuff width;
a staple positioned in said intermediate staple cavity, wherein said staple comprises a base and legs extending from said base, and wherein each leg is partially surrounded by one projection of said pair of projections;
a staple driver; and
