Improved Method of Securing the Scales or Handles to Knives,
Forks, and the like.
We, WILLIAM SEEDHOUSE of No. 62 Trafalgar Street, Sheffield, Cutlery
Manufacturer, and ALBERT JOHN HOBSON of the Firm of Thomas Turner
& Co., Suffolk Works, Suffolk Road, Sheffield, Cutlery Manufacturers, do hereby
declare the nature of this invention and in what manner the same is to be
5 performed, to be particularly described and ascertained in and by the following
statement:--
This invention relates more particularly to table cutlery having flat tangs to
which are fitted, so as to form a convenient handle, scales or pieces of wood, horn
or other suitable material, the said scales being generally dependent upon pins,
screws, or rivets for holding them together: and the object of our invention is to
dispense with all such fastenings and at the same time to secure the scales or
handles more firmly with less skilled labour.
In carrying our invention into practice, we take say an ordinary flat tang table
knife blade, and through the tang part, we punch a number of holes, we also take a
pair of scales and in the internal faces thereof we form a longitudinal dovetail
groove and slightly enlarge the outer end of said groove to form a better mouth or
opening for the reception of the molten metal hereafter to be poured therein.
When the scales and the blade have been secured in a suitably shaped mould or
clamp and if it be desired either for ornament or extra security, we also put
countersunk or conically shaped holes through the scales to correspond with holes
before referred to as being punched through the blade tang.
It is now only necessary to insert the scales and the blade in a suitable mould or
clamp as is well understood, when by filling the longitudinal groove in scales also
the holes through the tang the whole will become firmly secured together for their
whole length and form a more durable handle.
handle by a metal cap either with or without a metal bolster, technically known as
When it is desired to finish the
a "shell bolster," it is only necessary to have the blade with its tang cut out in one
piece from sheet steel, take scales prepared with groove as before and insert all in
a suitably shaped mould as before, when by filling such mould the metal cap and
bolster will be produced at the same operation as for securing the scales.
And in order that our invention may be better understood, we will now refer to
and explain the drawings hereunto annexed wherein,
Fig. 1. shows a portion of a knife blade with a solid bolster, and sundry holes
unched in tang.
Figs. 2 & 3 are respectively side and edge views of the same and show the form
nd extent of the molten metal poured in and constituting the fastening for scales,
aid scales being removed to enable the metal to be seen.
Figs. 4 & 6 are also respectively side and edge views illustrating scales for
ttaching by groove alone.
Fig. 5. shows a similar scale with groove and also having two countersunk holes

Fig. 7. represents a full finished knife and handle ready for use.
In practice, for blades having a solid bolster B, and a flat tang C, the blade A
made ready by trimming the bolster as usual, and punching holes through tang C
in Fig. 1. The scales D are prepared plain in the usual manner, we then cut
t or form a longitudinal dovetail groove E the whole length as in Fig. 4, and,
en extra security or ornament is required, put in holes as in Fig. 5. We then

scales upward, fill up the groove E and holes X with molten white metal as is well
understood, and so make all firm and solid, the handle and knife being complete
as in Fig. 7. except in respect of the usual finishing off. If however the scales are
broken away the metal marked F with projecting pieces X will be seen attached
to the tang C as in Figs. 2 & 3.
Likewise by taking a plain blade without holster B and putting it in a suitable
mould with a pair of scales D, the metal F will pass right through and so form
upon the blade A what is known as a shell bolster, and at the same operation,
when required, and in a properly shaped mould, a metal cap will also be produced on
the end all being as before, solid and complete at one operation, properly secured
without pins, screws, rivets or other extraneous fastenings, as now found to be
necessary, while the metal in the longitudinal groove renders the scale equally
secured throughout its whole length.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. In the flat tang of a blade shaped to receive scales, the formation therein of
holes for the purposes described and as illustrated by Fig. 1.
2. In scales to be attached to the flat tang of a blade, the formation therein of
a longitudinal dovetail groove, with or without transverse holes or openings for the
purposes described and substantially as illustrated by Figs. 4 & 5.
3. The whole combined method of securing, throughout their whole length, scales
or handles to blades, substantially as described and illustrated.
