This tool, of which our engraving is a good representation, comprises
a screw wrench, a pipe wrench, a hammer, a nail claw, a screw-driver,
and a bit handle, or socket wrench.
The bit handle is the entire tool, the square socket or opening being
made in the end of the handle, in which the shanks of bits may be
inserted.
The screw driver is formed on the end of the screw bar, attached to
the outer jaw of the wrench, and is taken out from the hollow of the
handle when required for use.
The use of the other parts of the tool will be apparent from the
engraving.
The tool is very compact, and has this advantage over the ordinary
screw wrench, that its leverage increases as it is opened to receive
nuts of larger size.
