Improvements in Knives, such as Paint and Putty Knives, Druggists'
Spatulas, Kitchen and Table Knives, and the Handles thereof.
I, JOHN EDWARD EVANS-JACKSON of 45 Holborn Viaduct, London, Patent
Agent, 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 :-
This invention relates to knives, such as druggists' spatulas, paint and putty
knives, kitchen and table knives, and the handles thereof.
The object of the invention is to produce a knife with a shankless blade, and a
wire or similar drawn metal handle, in which the handle and blade shall be firmly
and neatly secured together.
Figure 1 is a plan of a knife and handle, showing the bevel of the blade and
bend of the handle mainly on one side, as for kitchen and table knives.
Figure 2 is a plan of a spatula with the bevel of blade on both sides, and handle
centrally attached.
Figure 3 is a perspective of handle, shown on Fig. 2.
Figure 4 is a section of handle, Z, Z, Fig. 3.
Figures 5 and 6 are sections of the knife, on lines x-x, and y-y, Fig. 2.
Figures 7, 8 and
are broken views of different blades.
The knife blade is preferably of steel, and has about the usual taper of knife
blades for similar purposes. The blade A, Figs. 1 and 8 has the corner a cut away.
and the notches B are formed into the edge of the blade, near the end where the
handle is to be attached. These notches are preferably dovetailed, but may be of
other form.
In Figures 2, 7, and 9, the blade A' has both corners a¹ cut away, and along the
oblique edge notches B or B' are cut, bored, or otherwise formed.
The knife handle is made from a piece of wire or other drawn metal. The
piece constituting the handle is bent or bowed to shape, and the inner sides of
the bow are slotted or grooved longitudinally near the ends. The grooves can be
formed before or after the bending of the handle.
As shown in Figures 1, 2, and 3, the ends of the bowed handle are bent to
approximate the form of the end of the knife. The notched end of the blade is
slipped into the grooved end of the handle, and by a blow or pressure the handle
is compressed, so that the metal of the handle closes into the holes or
notches B or B' of the blade. (See Fig. 5.) The natural tendency of the handle
is to close on to the blade. The groove in the handle is made to closely fit the
blade. The blade generally tapers toward the point. Consequently the handle
may be quite firmly secured to the blade by pressure, even if the notches B be
omitted. But when these notches are employed, and the metal of the handle
pressed into the notches, the attachment of parts is exceedingly strong.
The ends of the wire forming the handle are preferably rounded, to give a neat
finish. The wire may be cylindrical, oval, or of other suitable and usual form.
For cheapness of construction the wire will generally be of uniform cross section,
but this is not essential. Steel wire may be used to advantage, or some of the
alloys. The knife may be plated, with nickel, silver, or other metal. Preferably
the plating is done after the blade and handle are permanently attached.
The wire or drawn metal of the handle gives great strength and toughness to the
handle. The blade, being cut from a rolled plate of suitable thickness and taper,

page_text: can be cheaply made, and is susceptible of a better temper and finish than if it had
a thickened shank.
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 I
claim is :-
1. The shankless knife blade having notches in the edges for the attachment of the
handle.
2. The shankless knife blade having the side,near the handle oblique to the edge,
and having notches in said oblique portion, and in the opposite edge, substantially as
described.
3. The combination with the shankless knife blade having notched edges, of the
bent wire handle grooved to embrace said notched portion of the blade, and com-
pressed to the blade, substantially as described.
4. The knife or spatula having oblique edges with dovetailed notches therein,
and the wire handle having groves embracing said edges and compressed into said
notches, substantially as described.
