PROVISIONAL SPECIFICATION.
Improved Form and Manufacture of "Knife Blades."
I, GEORGE HOPKIN WELLS, of 16, Portland Street, in the City of Sheffield,
Coach Smith, do hereby declare the nature of this invention to be as follows:-
Dealing with the method of manufacture and style of knife blades as hitherto
adopted, as and being made of a taper continued from the cutting edge to the
back or top of the blade, I, in lieu thereof, shape or make the same as follows
vizt. I make the taper commence from both the top and bottom of the blade,
and of correspondingly increasing width, so as to meet, and so meeting, in the
centre of same (as the thickest part) whereby, whilst providing and securing
the requisite strength for solidity and firmness in operation, I especially avoid
the difficulty usually experienced, in forcing through the material acted upon,
the whole surface of the blade so as hitherto augmented by the increasing
width of the taper throughout I find, on account of the point of strength being,
in my arrangement, so near the cutting edge, that slight tapers will suffice
(the top one however, being generally of the least thickness of the two) and in
any case, I usually make or leave the upper or dummy part or edge of the
blade, slightly thicker than that of the lower or cutting part of same.
invention is applicable to most knives in use, such as carvers, table knives,
butchers' knives, and otherwise.

This
Improved Form and Manufacture of Knife Blades.
I, GEORGE HOPKIN WELLS, of 16, Portland Street, in the City of Sheffield,
Coachsmith, 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:-
Dealing with the method of manufacture and style of knife blades as hitherto
adopted, as and being made of a single taper continued from the cutting edge to the
back or top of the blade, I, in lieu thereof, shape or make the same as follows
namely I make the taper commence from both the top and bottom of the
blade, and usually of correspondingly increasing width, so as to meet and so
meeting in the centre of the blade (as the thickest part) whereby, whilst pro-
viding and securing the requisite strength for solidity and firmness in operation,
I amongst other things, avoid the difficulty usually experienced, in forcing
through the material acted upon, the whole surface of the blade, so, as hitherto,

of the point of strength, being, in my arrangement, so near the cutting edge,
that slight tapers will suffice, the top one however, being in some cases of the
least thickness of the two. In any event, I usually make or leave the upper
part or edge of the blade, as a dummy one, and slightly thicker than that of the
lower or cutting part, and in some cases, it is found convenient to make the
centre or thickest part of the taper or tapers, either a little above or below
the centre of the blade. From the point of strength being, as stated, so near
the cutting edge, the blade also may be made somewhat thinner than is usually
the case, but this is a point which can only, in practice, be determined by the
quality and kind of blade required, and the purposes for which the same
employed.
This invention being, manifestly, so as to secure an effectual cutting edge,
with efficiency in operation, is applicable to most knives in use, such as carvers,
table knives, butchers' knives, and otherwise, but is especially applicable to
carvers. The accompanying drawing illustrates the invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, declare that what
I claim is
A new form or adaptation of same to knife blades, and method of manufacture,
to facilitate the operation in use, in the manner and substantially for the
purposes as hereinbefore described.
