An apparatus which simplifies removal of onion skin from an onion with its top and bottom removed, comprising: a skin contacting side; a cutting and spreading element extending downwards from a top end of the skin contacting side; the cutting and spreading element tapers downwardly from an upper wide portion to a bottom end to form a cutting tip located on a first vertical plane; the cutting tip is configured to create a cut along a contour on the onion as the cutting tip cuts into outermost onion layer(s) at a top end of the onion and slides downwards from the top end of the onion towards a bottom end of the onion; the upper wide portion of the cutting and spreading element is configured to enlarge the cut's width for facilitating user to spread the cut outermost onion layer(s) laterally from the cut with enlarged width and remove the outermost onion layer(s) with outer hard skin of the entire onion in one go; characterized in that: the apparatus further comprises a lifting member (31, 32) which extends outwards from the skin contacting side above the cutting and spreading element; the lifting member is wedge-shaped and projects downwards from an upper thick edge (311, 321) ending with a lower lifting edge (312, 322); the lifting member has an inner end (313, 323) which is proximal to the skin contacting side and an outer end (314, 324) opposite to the inner end; the lower lifting edge at the inner end is located on a second vertical plane which is at a first distance forward from the first vertical plane, and the lower lifting edge at the inner end is at a horizontal level which is at a second distance upward from the cutting tip; the lower lifting edge is configured to slot behind an inner edge of the cut outermost onion layer(s) after the cutting tip cuts into the outermost onion layer(s) to lift up portions of the onion layer(s) in contact with the cut outermost onion layer(s) as it slides downwards until it passes through the bottom end of the onion, thereby allowing the user to split apart the lifted portions along the cut to remove the outermost onion layer(s) together with outer hard skin of the entire onion in one go. a skin contacting side; a cutting and spreading element extending downwards from a top end of the skin contacting side; the cutting and spreading element tapers downwardly from an upper wide portion to a bottom end to form a cutting tip located on a first vertical plane; the cutting tip is configured to create a cut along a contour on the onion as the cutting tip cuts into outermost onion layer(s) at a top end of the onion and slides downwards from the top end of the onion towards a bottom end of the onion; the upper wide portion of the cutting and spreading element is configured to enlarge the cut's width for facilitating user to spread the cut outermost onion layer(s) laterally from the cut with enlarged width and remove the outermost onion layer(s) with outer hard skin of the entire onion in one go; characterized in that: the apparatus further comprises a lifting member (31, 32) which extends outwards from the skin contacting side above the cutting and spreading element; the lifting member is wedge-shaped and projects downwards from an upper thick edge (311, 321) ending with a lower lifting edge (312, 322); the lifting member has an inner end (313, 323) which is proximal to the skin contacting side and an outer end (314, 324) opposite to the inner end; the lower lifting edge at the inner end is located on a second vertical plane which is at a first distance forward from the first vertical plane, and the lower lifting edge at the inner end is at a horizontal level which is at a second distance upward from the cutting tip; the lower lifting edge is configured to slot behind an inner edge of the cut outermost onion layer(s) after the cutting tip cuts into the outermost onion layer(s) to lift up portions of the onion layer(s) in contact with the cut outermost onion layer(s) as it slides downwards until it passes through the bottom end of the onion, thereby allowing the user to split apart the lifted portions along the cut to remove the outermost onion layer(s) together with outer hard skin of the entire onion in one go.
