The invention discloses a
ceramic knife and a manufacturing method thereof. The
ceramic knife comprises a plastic hilt, a
ceramic blade and a
metal piece, wherein, the ceramic blade is spliced in the plastic hilt through a connecting sheet; the
metal piece is arranged in the outer position of the connecting sheet; a position equipped with the
metal piece on a structure to be heated is heated through a thermatron when the
ceramic knife is manufactured, molten plastic material is welded on the metal piece and the connecting sheet, and the
ceramic knife is obtained after the molten plastic material is cooled down. The
ceramic knife has a simple structure, the connection stability between the ceramic blade and the plastic hilt is easy to control, the finished product ratio is high, the manufacture effect can be controlled effectively, the manufacturing cost can be lowered greatly, the firm degree of formed structure is improved greatly by compared with the gluewater connection, the ceramic knife also has the
advantage of compact and beautiful appearance, and the installing and fixing speed of the ceramic knife can be increased greatly; in addition, the metal piece in the ceramic knife can be detected through a metal
detector when security inspection is carried out, so that safety accidents caused by the ceramic knife can be avoided.
