Abstract: A manually operable culinary apparatus includes a bottom cradle with a planar base member, a plurality of walls, a plurality of support plates, and a cutting implement detachably engaged with the bottom cradle in such a manner that the cutting implement is abutted directly on the bottom cradle when vertically and linearly displaced along a vertical plane such that a bottom-most tip of the cutting implement travels beyond the support edges and terminates medially between the support edges respectively. The apparatus further includes a mechanism for selectively adjusting first and second lateral spatial distances defined between the support plates and the anterior and posterior walls respectively.
