PROVISIONAL DEVITTUATION.
An Improved Paper Knife and Envelope Opener.
I, ALFRED JUBB of Station Street, Huddersfield in the County of York, Stationer.
do hereby declare the nature of this invention, which has been communicated to me
by Brower Brothers of Broadway New York United States of America to be as
follows:-
This invention consists in a special form of knife which has a narrow, pointed,
two-edged blade formed integrally with the handle.
In the construction of this knife I employ a narrow strip of sheet metal, by
preference steel, which may be electro or nickel plated and by means of a die,
cutter, or grinding apparatus I remove a portion of the metal from each side of the
strip for a few inches from one end thereof, leaving a narrow portion to form a
blade which is subsequently ground sharp upon both edges and a point is formed.
The parallel slip which is to form the handle is then bent at a right angle to the
line of the blade and again bent to a line parallel with the line of the blade and the
end is again bent at a right angle to this line whereby a portion of the slip forming
the handle of the knife stands up clear of and parallel with the surface upon which the
knife may be resting and is consequently readily grasped.
A hole is formed in the end of the handle to enable the knife to be suspended from -
a hook or nail.

COMPLETE SPECIFICATION.
An Improved Paper Knife and Envelope Opener.
1, ALFRED JUBB of Station Street Huddersfield in the County of York, Stationer,
do hereby declare the nature of this invention (which has been communicated to
me by Brower Brothers, of Broadway, New York,. in the United States of America)
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention consists in a special form of knife which has a narrow, pointed, two
edged blade, formed integrally with the handle.
In the construction of the knife I employ a narrow strip of sheet metal, by
preference steel, which is stamped in a die to the required form, or otherwise brought
into shape, and subsequently ground, polished, and nickel plated.
The parallel portion of the slip of metal which is to form a handle, is bent at a
right angle to the line of the blade, and again bent to a line parallel with the line of
the blade, and the end is again bent at a right angle to this line, whereby a portion
of the slip forming the handle stands up clear of the table or desk upon which the
knife is resting, and is therefore readily grasped.
A hole is formed in a projecting part at the end of the handle, whereby the knife
may be suspended from a hook or nail.
In order to enable my Invention to be fully understood I will proceed to describe
the same with reference to the accompanying drawings in which
Figure 1 represents a side elevation and Figure 2 a plan of my improved paper
knife.
The blade is represented at B, the handle at H, and the projecting portion of the
handle in which is formed a hole for suspension at A.

page_text: The blade is double edged, to enable it to cut in either direction, and is by preference
formed in one piece with the handle.
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 construction and form of a paper knife or envelope opener, the blade and
handle of which are formed together of one piece of metal, or other suitable material,
substantially as described and represented in the accompanying drawings.
2. In a paper knife or envelope opener, the handle and blade formed in parallel
planes, in order that the handle may be raised from the table or desk, and thereby
readily grasped, when the blade of the knife lies flat upon the table or desk, sub-
stantially as described and represented in the accompanying drawings.
Dated this Seventh day of October 1889
