<p>My "useless" screwdriver I made in metalworking class consisted
of steel or iron rod that I heated in a forge. While hot, I
hammered one end flat and then ground it into final shape. This
was then reheated and then quenched in water to temper it. For the
handle, I placed the rod with the finished blade in a sand mold
with a space to pour molten aluminum to fill out the handle.
Finally I ground the rough edges of the mold seam off the handle.<br>

<p>Viola! A pry bar that thinks it is a screwdriver :)</p>
