Steel pens, which have almost superseded quill pens, are made in

great quantities, and, like needles and pins, can only be produced

at a sufficiently low price to meet the requirements of the people,

by those who have erected buildings and fitted up machinery so as to

make the process sufficiently rapid to be cheap. The steel is first

selected of the proper quality, and rolled out into sheets of the

thickness required and of breadth sufficient for the length of the

pens to be made; these are punched out of the proper shape by a punch

worked by a screw, which cuts out a piece at every blow, and also the

perforation which terminates the split. The maker’s name or any other

device is stamped on this flat piece of steel, called a “blank,”

which is then coiled up into the shape required (whether a “barrel”

pen or a “nib”) by a sort of press, worked by a girl, as seen in the

engraving, and the split made by a machine, also engraved. In both

these machines the screw is worked with the left hand, while the

right is engaged in placing the pens under it and pushing out the

pen with the finger after it is bent or slit, these operations, from

constant practice, being performed with great rapidity. The pens have

next to be tempered, by being made red-hot and then thrown into water

or oil, and are afterwards polished by putting them into a barrel

with fine sand, which is turned round by a windlass for several

hours. The nibs or points are then finished at a stone which turns

round, and a varnish of a brown color--made by dissolving shellac

and asphaltum in naptha--is given to the surface to keep them from

rusting. Sometimes the surface is “blued,” which is done by heating

the pens on an iron plate till the blue color appears (see “Steel”).

Pens are sometimes made of other metals besides steel, as brass, or

zinc, and sometimes of gold. Those made of gold are, of course, too

expensive for general use, but as they are never corroded by the ink,

they last a very long time, and can always be cleaned by washing; and

as the whole wear is at the point, this is tipped with an alloy which

is exceedingly hard.
