AbstractIn one exemplar embodiment, a knife for de-veining, peeling and butterflying shrimp is disclosed having a handle and an elongated arcuate knife blade secured to the handle and extending forwardly thereof, the knife blade having an intermediate toothed blade portion disposed adjacent the handle and an arcuate blade portion extending forwardly of the intermediate toothed blade portion, the arcuate blade portion having a curvature approximating the body curvature of a de-headed shrimp. The arcuate blade portion has an upper convex cutting edge disposed thereon and a lower concave cutting edge adjacent the tip of the blade. The intermediate toothed blade portion has a plurality of spaced teeth aligned in a ramp configuration from front to rear adjacent the handle. When used, the knife tip is thrust through the body of a de-headed shrimp to slice the shrimp body along its longitudinal length to a depth traversed by the upper and lower cutting edges. The lower teeth of the intermediate toothed blade portion engage the shrimp vein in the visceral cavity and strip the vein from the shrimp body. The ramp-shaped intermediate toothed blade section also engages the shrimp shell to raise and loosen the shell from the shrimp body and then cleanly cut the shrimp shell longitudinally in alignment with the body slit created by the knife blade portion.
