Abstract
A utensil for opening a shell of a crustacean, such as crab, lobster and the like, has a pair of pivotally connected elongated members. Each elongate member has a handle portion and a head portion. A cutting blade is positioned in each of the head portions, the cutting blade having sharp inner edge to form a selected cut line through the shell of the crustacean. The cut line can be a uniformly straight line or defined by punctured openings that are made by serrated teeth provided on at least a portion of the cutting blade inner edge. The cutting blades are selectively brought in contact with the shelled crustacean positioned between the blades to sever the shell along a selected cut line without damaging the meat of the crustacean.
