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.
Viola! A pry bar that thinks it is a screwdriver :)
