A woodwork slicer apparatus is disclosed for slicing a thick veneer, which is pressed and advanced by a material feeding belt to a table surface. The material feeding belt, driven by power, is arranged so as to oppose a table, which includes a knife. The relief face of the knife is disposed so as to oppose a rand. There is a space between the relief face and the rand that is substantially the same as the thickness of the veneer to be sliced. Further, a guide, which is fixed by a fixing means so as to be in contact with the rand, is provided. For the above reasons, the veneer to be sliced is prevented from being cracked and is guided into a feeding direction along with the guide.
