Abstract: Apparatus and method for preparing cooked crabs for fast separation of lump crab meat from shell by a manual cleaving action is disclosed. The apparatus comprises a cutting board, having a cleaving means for severing a crab body in three easy steps. The cleaving means is used to sever the crab body along three imaginary lines as directed by instructional illustrations located on the cutting board. The cleaving means severs the crab body from the under side into three portions along diagonal imaginary lines extending between the front and rear of the crab. A third cut is made centrally along the central portion but does not cut through the upper shell of the crab thereby releasing the breastplate of crab with the lump crabmeat attached thereto for easy removal.
