ABSTRACT
As a result of modern development in Science and
Technology, most of the large scale industrial used machine were now
modernized to simple small and efficient machines. Some of these
machines were either operated manually or the aid of electricity.
For this reason, big metal sharpening machine was here reduced to
simple term, which can be operated manually such as file and grinding
machine for production firms and homes. This machine performs the same
functions as the large industrial metal sharpening and dulling device
which was reduced, but requires straight and also consumes time.
The
simple metal sharpening and dulling device was constructed with a metal
steel which is an old engineering materials. The following properties
were put into consideration such as long lasting of the metal, its
resistance to stresses and the preservation treatment of the metal steel
since the efficiency of the machine depends on the strength of the
metal steel and the grinding stone.
