PROVISIONAL SPECIFICATION.
Improvements in or connected with the Sharpening of Knives.
I, HENRY FRANK CHOPE of 53, Southbridge Road, Croydon, in the County of
Surrey, Ironmonger do hereby declare the nature of this invention to be as
follows:-
My invention relates to the sharpening of knives on ordinary table steels and
consists of attachments to either the knife or the steel for the purpose of guiding
the knife at the proper angle for sharpening it.
When secured to the steel the attachment or guide preferably consists of a
spring clip of hard sheet brass or other suitable material to engage with the steel,
and a loop or bow in which are slots at various angles to suit knives of different
thickness.
The slots may be either at right angles or oblique to the steel.
I may also form the attachment or guide from a block having a hole for the
steel, upon which it may be fixed by set screws, springs or other suitable means.
When secured to the knife the attachment or guide preferably consists of a bar
or rod of metal, having a longitudinal slit to engage with the back of the knife, to
which it is fixed by a wedge or other suitable means.

Improvements in or connected with the Sharpening of Knives.
I, HENRY FRANK CHOPE, of 33, St. John's Grove, late of 53, Southbridge
Road, Croydon, in the County of Surrey, Ironmonger 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 :-
My invention relates to the sharpening of knives on ordinary table steels, and
consists of an attachment to the steel for the purpose of guiding the knife at the
proper angle for sharpening it.
The attachment or guide may consist of a spring clip of hard sheet brass or
other suitable material to engage with the steel, and a loop or bow in which are
slote at various angles to suit knives of different thickness. The slots may be
either at right angles or oblique to the steel. The clip itself and the loop or bow
are formed in one piece, the sheet of metal being bent along the middle to form the
loop or bow and along each side of the middle to form corrugations or depressions
for gripping the steel. The edges of the sheet which are parallel to the lines of
bending may be turned or bent inwards or outwards to form feet or supports for
the attachment or guide.
I may also form the attachment or guide from a block having a hole for the
steel, upon which it may be fixed by set screws, springs, or other suitable means.
The construction which I have found most suitable for the purpose is a block of
wood, having a longitudinal hole for the steel and transverse slits opening into the
hole at the proper inclination. In this case the steel merely passes loosely through
Pred. }

page_text: the longitudinal hole; for I have not found it necessary to employ set-screws or
other means for fixing it thercin.
The accompanying drawing clearly illustrates this construction, Fig. 1 being a
front elevation and Fig. 2 an end elevation.
The block A, preferably of polished oak or other hard wood, has a longitudinal
hole B to receive the steel C, which is held by the handle in the usual way.
Two
oppositely inclined slits D are cut from the top or ends and lead to transverse
holes E, situated slightly above the axis of the longitudinal hole B. In operation
the block may rest on the table, and the knife F is drawn through each slit
alternately or otherwise until the sharpening is completed. My knife-sharpening
guide will be of great service to those who are not expert in the use of a steel,
and being made of polished wood will form a most ornainental object for the
table.
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. An attachment to ordinary table steels for the purpose of guiding knives in
the operation of sharpening, substantially as hereinbefore described.
2. A wooden block, having a longitudinal hole for the steel and transverse slits
for guiding knives in the operation of sharpening, substantially as herein before
described and as illustrated in the accompanying drawing.
Dated this 9th day of April 1895.
