Claims
I claim:
1. A knife comprising an elongated blade having an upper edge and a
lower cutting edge, a front portion and a widened rear portion, the
cutting edge being substantially straight in said rear portion and
curving convexly therefrom to said front portion, an opening in
said blade in said rear portion between said upper edge and said
substantially straight portion of said cutting edge and
substantially directly over said straight portion, and a handle
mounted to said blade above said opening, whereby a user may grasp
said handle with fingers received through said opening.
2. A knife according to claim 1 wherein the cutting edge and upper
edge are substantially parallel throughout at least a portion of
said widened rear portion.
3. A knife according to claim 1 wherein said blade has a rear edge
and said rear edge is substantially normal to the upper edge and
adjacent cutting edge.
4. A knife according to claim 3 wherein the blade has a curved
portion and a squared off front end lying substantially parallel to
the rear edge.
5. A knife according to claim 1 wherein the handle straddles the
upper edge of the blade and has a gripping portion terminating
downwardly in register with upper edges of the opening.
6. A knife according to claim 5 wherein the handle has portions
extending downwardly opposite the forward and rearward ends of the
opening.
7. The knife of claim 1 further including a front edge defined on
said blade and extending between said upper edge and said cutting
edge.
8. The knife of claim 1 wherein said opening resides entirely
within the edges of said blade.
Description
This invention relates to a kitchen knife of general utility
comprising a wide tapering blade and a handle straddling the back
of the knife in its wider portion, the rear end of the knife being
squared off and an elongated aperture, to receive the user's
fingers, being provided adjacent the handle.
It is an object of the invention to provide a knife having
excellent balance, the blade being designed for cutting through
such foodstuffs as meat, bread, vegetables and fruits by a
reciprocatory or "sawing" motion and also to be rocked, as on a
cutting board or bowl, to slice or chop a food into small strips or
pieces.
A practical embodiment of the invention is shown in the
accompanying drawing wherein:
FIG. 1 represents an elevation of the knife
FIG. 2 represents a vertical section on the line II--II of FIG. 1,
on a somewhat larger scale, and
FIG. 3 represents a detail elevation showing a modified form of tip
end.
Referring to the drawing, the knife blade 11 is shown as having a
straight back 12, a straight cutting edge portion 13 extending
about one-third the length of the blade, adjacent to the rear end
14, and a smoothly curved cutting edge portion 15 extending from
the straight portion to the tip end 16. The edge portion 13 lies
parallel to the back 12 and spaced therefrom by a substantial
distance, e.g., 3 inches. The rear end 14 and tip end 16 are
substantially normal to the back 12 and edge portion 13 or may be
angled about 5.degree. from normal. Instead of being squared off as
at 16, the tip end may be a sharp point 17, as shown in FIG. 3.
In the wide blade area above the edge portion 13 there is formed an
elongated aperture 18, shown as being centered above the center
line of the blade and of a size to receive easily the fingers of
the user, e.g. 31/2 by 1 inch.
A wooden handle 20 straddles the back of the blade above the
aperture 18, the handle having a smoothly rounded top surface 21,
rounded end portions 22, 23 projecting downwardly at the front and
rear ends of the aperture and a gripping surface 24 which is
smoothly rounded and forms a continuation of the upper edge 25 of
the aperture, as clearly shown in FIG. 2. The handle is held
rigidly on the blade by means of rivets 26.
When the blade edges 13, 15 are formed by a single bevel (at an
angle of about 10.degree.) the knife is adaptable to the neat
cutting of materials such as cheese as well as to other cutting
procedures for which double bevel blades are normally used. A bevel
at the angle mentioned facilitates sharpening without the
possibility of damaging the handle. A double bevel could be
provided if desired. The blade may suitably be stainless steel with
a hardness of 50-55R. and the handle may be any customary hard wood
or a durable plastic.
In use, the location of the handle on the back of the knife blade
in line with the cutting edge improves the user's control of the
blade and facilitates such operations as cutting, slicing and
chopping. There is provided, also, a long blade (e.g. 15 inches)
which is not further extended to an inconvenient length by having a
handle on the end.
In view of the foregoing description it will be apparent that the
invention is not limited to the specific details set forth therein
for the purposes of illustration, and that various other
modifications are equivalent for the stated and illustrated
functions without departing from the spirit and scope of the
invention.
