Simply insert the OXO Good Grips Shrimp Cleaner into the end of the shrimp and the ridged edge will split the shell and remove the vein in one motion. The guard helps protect your hands while youre working with slippery shrimp, and the asymmetrical design allows for use at a variety of angles. A soft handle makes this Shrimp Cleaner comfortable to use and non-slip, even in wet hands.
