A mandoline slicer, comprising: a slicing ramp having a proximal ramp portion and a distal ramp portion carried on a frame having opposing sidewalls (33, 34), a gap being defined between the proximal ramp portion and the distal ramp portion; the distal ramp portion having a slicing blade mounted along an edge of the distal ramp portion along the gap, the slicing blade having a sharpened edge facing toward the proximal ramp portion; the proximal ramp portion having a first end adjacent the distal ramp portion and an opposite second end, the second end being pivotally mounted to the frame between the opposing sidewalls (33, 34); the proximal ramp portion further having an upper side and a lower side, the lower side having at least one rib extending downward from the lower side, the rib having a height below the lower side, the height of the rib decreasing as the rib extends from the first end of the proximal ramp portion toward the second end of the proximal ramp portion; and a support structure engaging the at least one rib and supporting the proximal ramp portion, the support structure being movable along a length of the rib; whereby movement of the support structure in a first direction causes the proximal ramp portion to be raised, and movement of the support structure in a second direction causes the proximal ramp portion to be lowered; and wherein the at least one rib further comprises a plurality of ribs, characterised in that each of the plurality of ribs further comprises a plurality of heights, the plurality of heights being defined as separate steps, the steps decreasing in height as the ribs extend from the first end of the proximal ramp portion toward the second end of the proximal ramp portion. a slicing ramp having a proximal ramp portion and a distal ramp portion carried on a frame having opposing sidewalls (33, 34), a gap being defined between the proximal ramp portion and the distal ramp portion; the distal ramp portion having a slicing blade mounted along an edge of the distal ramp portion along the gap, the slicing blade having a sharpened edge facing toward the proximal ramp portion; the proximal ramp portion having a first end adjacent the distal ramp portion and an opposite second end, the second end being pivotally mounted to the frame between the opposing sidewalls (33, 34); the proximal ramp portion further having an upper side and a lower side, the lower side having at least one rib extending downward from the lower side, the rib having a height below the lower side, the height of the rib decreasing as the rib extends from the first end of the proximal ramp portion toward the second end of the proximal ramp portion; and a support structure engaging the at least one rib and supporting the proximal ramp portion, the support structure being movable along a length of the rib; whereby movement of the support structure in a first direction causes the proximal ramp portion to be raised, and movement of the support structure in a second direction causes the proximal ramp portion to be lowered; and wherein the at least one rib further comprises a plurality of ribs, characterised in that each of the plurality of ribs further comprises a plurality of heights, the plurality of heights being defined as separate steps, the steps decreasing in height as the ribs extend from the first end of the proximal ramp portion toward the second end of the proximal ramp portion.
