CHARLES IBBOTSON Cutlery Manufacturer 58 Cambridge Street, Sheffield
do hereby declare the nature of this invention to be as follows:-
To enable me to fix wood or other handles onto scale tang table or butchers'
knife blades without pins or revits, first, I cut the blade & taug in one piece
out of sheet steel, the tang full breadth of handle, but only half length, I then
dovetail the head end of tang the shape of an inverted saw tooth or VI then
slit the handle straight across with a saw half way down its length, holding the
saw a little to each edge which leaves a small peak or dovetail in centre, which
will fit into the V in end of tang; I now fix tang inside slit in handle, forcing
it tight into fitting the V in blade tang, this prevents tang from slipping sideways,.
I then run on a white metal bolster at blade end, this thoroughly fastens the
handle without revits, I also attain same results by taking same kind of blade and
handle, but instead of dovetailing the blade tang V shape, I form the blade taug
with a small projecting peg in center of end of tang, I then slit the handle straight
across, halfway down its length, I then drill a small hole in center-of-slit in handle,.
I then fix the blade tang in slit, and force the projecting peg on center of tang
end, into the hole in center of slit in handle, which prevents tang from slipping
sideways, I now run on a white metal bolster, which makes a fast handle
without revits.
What I claim as new is the V shaping and the projecting peg on tang ends.
of blades, and corresponding, shaping of slits in handles to fit the tang ends.

Improvements in Hafting Table and Butchers' Knives.
CHARLES IBBOTSON Cutlery Manufacturer 58 Cambridge Street Sheffield
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 :—
To enable me to fix wood or other handles onto scale tang or whittal tang
table knives, butchers' knives & sheath knives, without pins or revits. Firstly
for scale tangs I fly or cut out the blade & tang in one piece out of sheet steel,
the tang full breadth of handle, but only one quarter, or one half or other length
as required, I then dovetail the head end of the tang the shape of a V (see Figure 1).
I then slit the handle straight across with a saw half way or other distance down
its length as required, holding the saw a little to each edge which leaves a small
peak or dovetail in center which will fit into the V in end of tang, I now fix tang
inside the slit in handle, forcing it tight into fitting the ✓ in blade tang
(see Figure 2.) this prevents tang from slipping sideways, I then run on a white
metal bolster at blade end which grips the handle and fastens it without pins or
revits. I also attain same results by taking same kind of blade and handle, but
instead of dovetailing the blade tang V shape, I form the blade tang with a
projecting peg or whittal taug, any length required in center of end of tang, I then
slit the handle straight across, half way (or any other distance as required) down its
length, I next drill a small hole in center of slit in handle; fix the blade tang in
slit in handle & force the projecting peg or whittal tang on end of blade tang

page_text: into hole in center of slit in handle (see Fig. 3 & 4) which prevents the tang from
slipping sideways out of the slit in handle, I now run on a white metal bolster as
before, which makes the handle quite fast without pins or revits.
The following letters explain the different drawings herewith.
A. Blade & tang as flyed out in one piece.
B. Handle showing slit as made by saw, any length as required.
C. Section of handle showing peak or dovetail (Sheet 1.) and hole for projecting
peg (Sheet 2.) & hole for whittal tang (Sheet 3.).
D. Finished knife, the dotted lines show how the blade tangs and handles fit.
E. White metal bolster, run on, which holds the blade and handle in position
and thoroughly fast.
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 [
claim is
The shaping & projecting peg or whittal tang on end of blade tang with the
corresponding dovetailing & hole in handle, combined with the fixing and fastening
of the tang without pins or revits.
