Improvements in Steels for Whetting Cutlery.
I, EDWARD TUTHILL MARKILAM, of 41 and 42, Cloth Fair, in the City of London,
Wholesale Cutler and Electroplater, do hereby declare the nature of this invention
to be as follows:
The object of my invention is to provide a steel for whetting cutlery that shall
afford facility for both sharpening and setting, thus taking the place of the two
separate tools heretofore used. For this purpose I make the blade of the steel
with two kinds of surfaces, one kind rough for sharpening and one kind smooth
for setting. The form of the tool both in the length direction and in cross
section may be greatly varied. Thus the cross section may for instance be some-
what like oval that is with two opposite curved faces roughened for sharpening
purposes while the two narrow edges are plain or smooth for setting purposes. In
the length direction the form may for instance be with about parallel edges for
some distance from the handle and then gradually tapering towards the point.
But the tool may if desired be of the same width and thickness throughout the
length. Or it may be a gradual taper from the point to the handle both in
thickness and width. Another suitable section of blade is that of a flattened six
sided form having four large sides or faces rough and smooth on opposite sides and
two smaller or narrow faces or edges which are smooth and which may be used
for giving a finishing setting; or instead of the six sides I may have only four,
the two narrow edges or sides being omitted.

Improvements in Steels for whetting Cutlery.
I, EDWARD TUTHILL MARKHAM, of 41 and 42, Cloth Fair, in the City of London,
Wholesale Cutler and Electroplater, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement: —
The object of my invention is to provide a steel for whetting cutlery that shall
afford facility for both sharpening and setting, thus taking the place of separate
tools heretofore used. For this purpose I make the blade of the steel with
different kinds of surfaces for accelerating the sharpening and setting. The form
of the tool both in the length direction and in cross section may be varied but
I prefer to make it of the cross section shewn in Fig. 1 or somewhat oval that is
077

page_text: with two opposite curved faces a a coarsely cut or grooved longitudinally for
sharpening while the two narrow faces or edges bb are very finely cut or grooved
for setting purposes. The faces a a might be flat but their action would not be
so useful or effective.
In the length direction the form may, for instance as shewn in Fig. 2 be with
about parallel edges for some distance from the handle and then gradually tapering
towards the point but the tool may if desired be of the same width and thickness
throughout the length or it may be a gradual taper from the handle to the point
both in thickness and in width.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
The combination in one cutlery whetting and setting steel of two different kinds
of operating surfaces the said steel being of a flat or oval section with narrow
flat edges and having the flat or curved surfaces a a coarsely grooved or cut and
the flat finishing edges bb very finely grooved or cut substantially as set forth.
Dated this Seventh day of June 1898.
