Improvements in Knives.
I, RUSS JACKSON CHRISTY of Fremont, Ohio, U.S.A., Mechanic, do hereby
declare the nature of my invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This knife is composed entirely of metal, both blade and handle. The blade
has teeth of serpentine form, the teeth and spaces between the teeth being
curved in reflex curves. The teeth and interdental spaces are ground to a sharp
edge, and the bevel is preferably all one face of the blade. In such case the teeth
and the spaces between the teeth can be sharpened by grinding the flat or
unbeveled face of the blade on a common grindstone. The blade is provided with
dovetailed recesses, by which the handle is attached.
The handle consists of a beut wire, grooved or slotted at the parts which embrace
the blade, and secured to the blade by compressing on the blade.
Fig. 1 is a side elevation of the knife showing the beveled side of the blade, and
the wire handle attached to the back and end of the blade. The handle is shown
in end elevation in Fig. 2, and a part of the blade is shown in Fig. 3.
Fig. 4 is a side view of a knife with handle attached at both sides of the blade.
Fig. 5 is a section of same on line xx, and Fig. 6 is a reverse view of part of the
blade.
Fig. 7 is an enlarged perspective view of part of a blade showing beveled face,
and Fig. 8 a similar view of plane face of the blade.
The blades A are preferably made of sheet steel, the plane faces being parallel.
The notches B B are cut from the blades, in proper position to attach the handle.
The wire handle C is slotted in one or both sides as at D, or in the side and
across the end, and the wire is bent to such form as to make a convenient bandle.
The slotted part of the wire is made to embrace the blade at the notches, and the
metal is compressed so that it enters the notches B. The metal thus forms tongues
which flow into and enter the notches, and the blade and handle are thus firmly
secured together. The part of the wire which embraces the blade serves to brace
and strengthen the same.
The teeth E may be formed by grinding on a corrugated grindstone, or on a
stone with a rounding face. The teeth and the spaces between them are preferably
counterparts of each other, and the bevel all on one side.
This knife is a convenient knife for the pantry. The handle serves to hang up
the knife when desirable. The handle is very strong, and firmly secured without
rivets. The peculiar toothed blade is operated like a saw, and will cut bread,
cake, and the like without crumbling. It can be used a very long time for cutting
bread without the necessity of grinding, and can be ground on a common grindstone
so that the teeth and the spaces between the teeth are sharp. The blade and handle
are frequently nickel plated.
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 knife having a notched blade and a slotted wire handle, the blade and
handle united together without rivets in the manner substantially as described.

page_text: 2. The bread knife having blade with the peculiar curved teeth substantially as
described, the teeth and interdental spaces being beveled to an edge in the manner
substantially as described.
