COMPLETE SPECIFICATION..
Improvements in Knife Sharpeners.
I, HENRY LANDGRAF, a citizen of the United States, residing at 8 Maiden
Lane, of New York City, in the County of New York, and State of New York,
U.S.A. Jeweller, 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 knife sharpeners or "steels," such as are usually
employed for sharpening carving knives, table knives, and other knives of this
class, and the object thereof, is to provide an improved device of this class,
which is simple in construction and operation, and which in addition to the usual
"steel," is provided with a plurality of "steel" disks mounted on separate shafts,
the perimeters of which are beveled or sharpened, and which are adapted to form
an edge on a knife when the latter is drawn between the same.
The invention is fully disclosed in the following Specification, of which the
accompanying drawing forms a part, in which ;-
Fig. 1, is a side view of my improved knife sharpener; and,
Fig. 2, a plan view thereof.
In the practice of my invention, I provide a sharpener for knives, and similar
articles comprising a handle A, with which is connected a "steel" B, of the
usual form, and the "steel" B, is connected with the handle A, by means of
parallel jaws D, and mounted in said parallel jaws D, are two shafts d, which
are arranged at a predetermined distance apart; and mounted on each of the
shafts d, are a plurality of circular disks d 2.
The perimeters of the disks d2, on one of the shafts d, are all beveled on the
same side, and those on the other shaft are beveled on the opposite side, this
construction being clearly shown in Fig. 2, and the arrangement of the disks d 2,
on the shafts d, is such that the edges of the disks on one shaft, slightly overlap
the edges of the disks on the other shaft, as is also clearly shown in Figs. 1 and 2,
and the operation will be readily understood from the foregoing description when
taken in connection with the accompanying drawing.
In employing the "steel" B, to sharpen a knife, the latter is applied thereto, in
the usual manner, and as will be readily understood by all those familiar with this
class or devices, and when the knife is really dull and it is desired to form an edge
thereon, the blade is drawn transversely. between the separate series of disks, as
will also be well understood, and the upper sides of the jaws D, are each provided
with a notch or recess C, which is in line with the space between the disks d 2, of
the separate shafts d.
This device is simple in construction and operation, and is comparatively
inexpensive, and it will be seen that by means of the combination of two simple
forms of construction, I produce a knife sharpener which is perfectly adapted to
accomplish the result for which it is intended, and which involve the best elements
of devices of this class.
My invention is not limited to the form of the various parts thereof, and I
reserve the right to make all such changes therein, and modifications thereof, as
fairly come within the scope of the invention.
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 herein described knife charnaner comprising a handle and "steal"

page_text: as B, said "steel" being connected with said handle by parallel jaws, in which
are mounted two shafts, each shaft being provided with a plurality of disks,
substantially as shown and described.
2. The herein described knife sharpener, comprising a handle, and a "steel"
as B, said "steel" being connected with said handle by parallel jaws, in which
are mounted two shafts, each shaft being provided with a plurality of disks,
and the disks on each shaft being beveled so as to form cutting edges, the
disks on one shaft being all beveled on the same side, and those on the other
shaft being beveled on the opposite side, substantially as shown and described.
3. The herein described knife sharpener, comprising a handle, and a "steel"
as B, said "steel" being connected with said handle by parallel jaws, in which are
mounted two shafts, each shaft being provided with a plurality of disks, and the
disks on each shaft being beveled so as to form cutting edges, the disks on one
shaft being all beveled on the same side, and those on the other shaft being
beveled on the opposite side and the disks being so located that the cutting edges
thereof, slightly overlap, and the jaws between which the disks are pivoted being
provided with notches or recesses, at the points where the edges of the disks meet,
substantially as shown and described.
