The present invention is directed to a mold. The present invention is also directed to a device for processing the same, and a replica made therefrom. A device for processing the mold comprises a cutting unit carving a surface of the mold; a housing accommodating the cutting unit and having an aperture through which a portion of the cutting unit protrudes; at least one piezo-electric element disposed between the cutting unit and the housing; and a signal generator applying an electrical signal to the piezoelectric element. The mold comprises a plurality of linear peaks and grooves that are formed on a surface of the mold, wherein both or one of the peaks and grooves have random or periodic meandering-shape. A replica manufactured by the mold comprises a plurality of linear crests and valleys that are formed on a surface of the replica, wherein both or one of the crests and valleys have random or periodic meandering-shape.
