This is the scalloped S173SC on a coded handle. The serrated edge means it spreads on the flat and then draws through a roll or a finished round, so a station handling meat fillings does not need to reach for a second blade to halve the sandwich.
Red assigns it to meat products. That matters more on a scalloped spreader than a plain one, because the serrations hold residue that a flat blade would not, making a shared tool harder to clean between fillings.
Dexter-Russell has made cutlery in Southbridge, Massachusetts since 1818 and is the oldest cutlery manufacturer in the United States. The Sani-Safe line is its NSF-certified foodservice range, built around a textured polypropylene handle moulded to the tang so there is no seam for food to lodge in.
