Fuente: WIPO "tomato" A cutting board apparatus includes a base member with a cutting surface and four sidewalls extending upwardly from the edges of the base member to contain food items during cutting operations. Three sidewalls are fixed to the base member while a fourth sidewall is removably coupled through retention mechanisms disposed on the two opposing sidewalls. The retention mechanisms allow the removable sidewall to be secured in an installed position during cutting operations and to be disengaged and removed when transfer of prepared ingredients is desired. When installed, the four sidewalls create a complete perimeter barrier preventing food scatter. When the fourth sidewall is removed, an unobstructed opening is created at one edge of the cutting board, enabling direct transfer of cut ingredients into cooking vessels or containers without tilting the board or using additional tools. The apparatus improves food preparation efficiency while reducing waste and maintaining kitchen cleanliness.
