6 Claims. (Cl. 30-295)
This invention relates to knives of that type
provided with a ?nger rest operating over the un
sharpened edge of the knife blade adjoining the
inner end of the handle and has for its object the
provision of a ?nger rest construction and
mounting. therefor, that will ?rmly and securely
anchor the ?nger rest in position and so hold
it there that‘it will have no tendency to become
loose or be capable of any appreciable movement
10 relatively either to the blade or to the handle of
the knife.
With the above and other objects in view, as
will be apparent, this invention consists in the
construction, combination and arrangement of
ing formed from any adaptable material, pref
erably and usually of wood. A knife blade II,
provided with a shank I2, is attached to the han
dle I0 by having the shank I2 embedded in the
handle II]. This shank I2 may be held in its po
sition within the handle I0 by friction but if so
desired, a headed pin or brad I3 may be driven
into one side of the handle I0 to engage said 10
shank I2 thereby ?rmly holding the shank in the
handle ID.
The inner end 'of the handle I0 is shouldered,
as at I4, and has a ferrule I5 mounted thereon.
parts all as hereinafter more ‘fully described,
The outer extremity I6 of’ the ferrule I5 is closed
claimed and illustrated in the accompanying
by a face which covers the end or inner end of
the handle I0 and through which the shank I2
must pass to become embedded in said handle.
To that end a vertical slot I1 is provided in the
facepl? of the ferrule 15 and is crossed and inter
drawing, wherein:
‘
Fig. 1 is a side elevation of a knife constructed
in accordance with the present invention‘;
Fig. 2 is a bottom plan view thereof;
Fig. 3 is an elevation of the knife as ‘viewed
from the point of the blade thereof; and
Fig. 4 is an elevation of the end face of the
ferrule mounted on the inner end of the handle
25 of the knife, showing the construction by which
it cooperates with both the ?nger rest and the
shank of the knife blade.v
Heretofore in the construction of knives em
bodying ?nger rests, it has generally been cus
tomary to either form the ?nger rest integrally
with the unsharpened edge of the blade adjoining
the inner end of the handle; or to provide a lat
erally disposed extension at the inner extremity
of the ?nger rest, having an opening therein‘for
the passage of the blade shank whereby the ex
tension is clamped between the inner end of the
handle and the inner extremity of the blade; or
to provide a tongue or tongues at the inner end
of the finger rest which are driven into the handle
upon each side of and usually flush against the
shank of the blade. These prior constructions
are open to certain objections, principally be
cause of the ?nger rest frequently becoming loos
ened and having some appreciable movement rel
atively to the blade and handle.
The present invention contemplates a ?nger
rest that will be securely and ?rmly held in its
position with reference to the unsharpened edge
of the blade adjoining the inner end thereof and
v which will be substantially incapable of becoming
loosened or having movement relatively to either
the blade or the handle, thereby overcoming the
principal objections to most forms of ?nger rests
which have gone before.

knife having any suitable shape and size and be

Reference being had more particularly to the
cepted by a horizontal slot I8 likewise formed in
the face. I6. These slots I‘! and I8 are positioned
centrally with respect to the diameter of the fer
rule I5 and cross or intercept each other at the
approximate center of the face I6 of the ferrule.
The shank I2 of the blade I I passes through the
vertical slot I ‘I in the face I6 of the ferrule I5
and rather snugly occupies the entire slot. Thus
when the shank I2 of the blade II is in its op
erative position, the ferrule I5 is ?xed on the 30
reduced or shouldered extremity I4 of the handle
I0 and any tendency for movement thereof with
reference to either the handle ID or the blade I I
is largely overcome.
A ?nger rest I9 of any suitable shape and con 35
struction bears over the inner end portion of the
unsharpened edge‘of the blade I I and provides or
creates a relatively wide rest for the index ?nger
of the user of the knife. The inner extremity 28
of the ?nger rest I9 is bent downwardly at sub
stantially right angles to the body of the ?nger
rest to occupy a position ?ush against the face
I6 of the ferrule I5. This right angularly dis
posed extension 20 of the ?nger rest I9 termi
nates in substantial alignment with the horizon
tal slot I8 in the face I6 of the ferrule I5.
At its extremity this right angularly disposed
extension 20 of the ?nger rest I 9 is provided with
two tongues 2| spaced one from the other later
ally of the extension and extending rearwardly
therefrom upon each side of the shank I2 of the
blade II. One of these tongues passes through
each portion of the slot I8 in the face I6 of the
ferrule upon opposed sides of the vertical slot I1
and therefore may be and are embedded horizon- -

tally in the inner end portion of the handle I0
?anking and adjoining the shank [2 of the blade
I I which rests vertically within the handle.
Movement of the ?nger rest I9 laterally with
reference to the plane of the blade II, or to the
handle I0, is effectively prevented by the engage
ment of the tongues 2I with the limits of the slot
having a handle shank at one extremity thereof,
of a handle adapted to receive and engage said
shank, a ?nger rest coacting with the inner end
portion of the unsharpened edge of the blade, a
ferrule mounted on the inner end of said handle
having a vertical slot therein for the passage of
the handle shank and a horizontal slot crossing
I8 in the face I6 of the ferrule I5 and any move
said vertical slot, and rearwardly extending
tongues carried by said ?nger rest adapted to
ment of the ?nger rest I9 longitudinally of the
10 blade II and away from the handle I0 is pre
vented by the partial engagement of the exten
sion 20 of the ?nger rest I9 between the inner
extremity of the knife blade II and the face I6
of the ferrule I5.

This construction provides additional security
over and above the normal frictional engage
ment of the tongues 2| with the handle I0 for
holding the ?nger rest I9 ?rmly and securely in
position.

From the foregoing it is manifest that the pres
pass through said horizontal slot and be em 10
bedded in said handle upon each side of the
handle shank aforesaid.
4. In a knife, the combination with a blade
having a handle shank at one extremity thereof,
of a handle adapted to receive and engage said
shank, a ?nger rest coacting with the inner end
portion of the unsharpened edge of the blade, a
ferrule mounted on the inner end of said handle
having a closed outer end and a vertical slot
therein for the passage of the handle shank and 20
a horizontal slot intercepting said vertical slot, a
ent invention provides a mounting for a ?nger
rest cooperating with the unsharpened edge of a
right angularly disposed extension on said ?nger
knife blade that will prevent the ?nger rest from
rest, and rearwardly extending tongues on said
extension adapted to pass through the horizontal
becoming loosened or having any substantial or
25 noticeable movement relatively to the knife blade
or to the handle of the knife. In other words,
any turning action of the blade II, ferrule I5, or
?nger rest I9 with respect to the handle I0, is
effectively overcome by the coaction of the shank
30 I2 and the tongues v2I with the slots I1 and I8
of the ferrule and with the body of the handle I0.
What is claimed is:
1. In a knife, the combination with a blade
having a handle shank at one extremity thereof,
35 of a handle adapted to receive and engage said
shank, a ?nger rest‘coacting with the inner end
portion of the unsharpened edge of the blade, a
ferrule mounted on the inner end of said handle
having a closed outer end and a vertical slot
therein for the passage of the handle shank and
a horizontal slot crossing said vertical slot, and
slot aforesaid and be received or embedded with 25
in the handle upon each side of said handle
shank.
