Improvements in Edge Tools.
I, JOHN ARTHUR INNOCENT, of 8, Conduit Road, Sheffield, in the County of
York, Cutlery Manager; do hereby declare the nature of my said invention to be
as follows:-
The object of my invention is to simplify and cheapen the manufacture of
certain classes of edge tools, such for example as chopping or mincing knives and
the like implements.
A chopping or mincing knife as ordinarily made for use by hand, is formed with
a tang or tangs which are inserted or secured to a detachable handle or haft of wood
or other substance.
By my invention I construct the blade, tang and haft all in one piece of steel or
other suitable metal or metallic alloy, and although such knives or choppers are
sometimes made with a orescent shaped blade and sometimes with a rectangular
shaped blade, a description of the latter form will suffice to explain the nature of
my invention which relates more particularly to the formation of the tang or tangs
and handle in combination with the blade, than to any particular form or shape
of the blade.
I carry out my invention in the following manner. Out of a sheet or strip of
steel of the required temper I cut or shear a rectangular piece of the required size
which I call the blank, one end of which will form the blade of the implement and
the other end the handle of the same, the handle is then formed by turning or
rolling that end of the blank towards the blade end until it forms a tube of
convenient size, such tubular handle being the whole width of the blade and
parallel to it.
Out of the body of the blank, i.e. between the handle and the blade, I then cut,
punch, or stamp a rectangular piece about the width of a persons hand so as to
leave a strip at each side to form a tang, and a broader strip at the bottom to form
the blade, the top edge of the space, so made, being close up to and parallel with
the haudle, which is set back so that its vertical axis is brought in line with the
tange and the blade. The space below the handle already referred to being made
deep enough as well as wide enough for a persons hand to be passed through for
the purpose of gripping the tubular handle. The blade is then ground, hardened
and tempered, when the knife or chopper is ready for use.
In some cases the handle may be covered or partly covered' with leather or other
suitable substance.
As a modification of the above mode of manufacture, I sometimes shear, cut,
punch, or stamp the blank out of a strip all at one operation, in which case the
handle would be afterwards formed, as previously described.
As a further modification, in order to provide my improved chopping or mincing
knife with two or more cutting edges, 1 sometimes screw an additional blade on one
side or an additional blade on each side of my improved chopping or mincing knife,
such blades being kept a proper. distance apart by the insertion of metallic rings or
ferrules or by blocks of wood or other suitable material.
Dated this 25th day of January 1896.

...Improvements in Edge. Tools.
1, JOHN ARTHUR-INNOCENT, of 8 Conduit Road, Sheffield, in the County of
York, Cutlery. Manager, do hereby declare the nature of my said invention and in
what manner the same is tober performed torbe particularly described and
ascertained in and by the following statement :-
"The object of my invention is to simplify and cheapen the manufacture of
certain classes of edge tools; such for example as chopping or mincing 'knives and
the like implements.
A chopping or mincing knife as ordinarily made for use by hand, is formed with
ataug or tangs which are inserted or secured to a detachable lhandle or haft of wood"
or other substance.
By my invention I construct (the blade,.tang andihaft all in one piece of steel or
other suitable metal or metallic alloy and although such iknives or choppers
are sometimes made with a crescent shaped blade and sometimes with a rectangular
shaped blade a description of the latter form will suffice.to explain the nature of
my invention which relates more particularly to the formation of the tang or
tangstand handle in combination with the blade; than to any particular form or
shape of the blade.
Icarry out my invention in the following manner.
Out of a sheet or strip of steel of the required temper I cut or shear a rectangular
piece of the required size which I call the blank, one end of which will form the
blade of the implement and the other end the handle of the same, the handle is then
formed by turning orirolling that end of the blank towards the blade end until it
Informs a tubesoficonvenient size, such tubular handle being theiwhole width of the
blade and parallel to it.
Out of the body of the blank, i.e., between the handle and the blade, I then out,
punch, oristamp a rectangular or other convenient formed piece about the width of
a persons hand so as to leave a strip at each side to form a tang, and a broader
strip at the bottoin to form the blade, the top edge of the space so made, being close
of up to and parallel with the handle, which is set back so that its: vertical axis
a is brought in line with the tangs and the blade. The space below the handle
already referred to being made deep renough as: well as wide enough for a persons
eithand to be passed through for the purpose of gripping the subular handle.
The blade is then hardened, tempered and ground, when the knife or chopper is
ready for use.
:
In some cases the bandle may be covered or partly covered with leather or other
suitable substance.
:
As a modification. of the above mode of manufacture, I sometimes: shear, cut,
punch or stamp the blank out of a strip all at one operation, in which case
the handle would-be afterwards formed, as previously described.
The nature of my invention will be better understood on reference to the
accompanying sheet:ofidrawings, in which,
Fig. 1:represents the blank.
Fig. 2.represents the said blank, with one end turned or rolled to form the
tubular handle.
Fig. 3. is the same after a piece has been cut,punched, or stamped out of
the body.
Fig. 4. is an end view.
*!! ...
The same.letters refer to similar,parts throughout the several views.
a, is the blade of the implement.

page_text: c, is the space formed by cutting, punching or stamping a piece of the material
out of the body of the implement.
d, d, are the strips or tangs connecting the blade with the handle.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is,
1. In a chopping or mincing knife, constructing the whole implement, that is to
say, the blade, the tangs and the handle, all in one piece out of the same piece of
steel or other suitable material in the manner and for the purposes substantially as
herein described and illustrated in the accompanying sheet of drawings.
