This invention relates to an improved and novel

factory hand-type cutting tool such as is re
quired to efficiently cut so-called leather strings at I6. The numeral I ‘I designates an appropri
10 such as are employed in belt lacings and braided 4
work of different types. With this suggestion and
challenge in mind, I have therefore evolved and
produced a simple and economical hand cutter
which will do the work well and which adapts
15 itself to satisfactory cutting of water soaked raw
hide, buckskin and old and new sheets of leather
and equivalent material.
In selecting what I now believe to be well
chosen features, I have brought into being a
20 unique hand cutter susceptible of accommodating
an ordinary penknife blade and characterized by
' a body formation which functions as the platen,
this being equipped with guard and gauge means
coacting with requisite precision to determine
25 the width of the string to be cut and to permit
uniform properly gauged cutting thereof.
Other features and advantages will become
more readily apparent from the following de
scription and drawings.

In the drawings, wherein like numerals are em
ployed to designate like parts throughout the
views:
Figure 1 is a top plan view of a tool construct
ed in accordance with my ideas showing the man
35 ner in which the same may be used.
Figure 2- is a view like Figure 1 with the work
or sheet of leather removed to expose the details
with greater clarity.
Figure 3 is what may be called an end view,
40 that is, an end elevational view detailing the
blade mounting.
Figure 4 is a top plan view of the body or platen
forming plate with the guard and gauge and blade
removed.

Figures 5 and 6 are sections on the lines 5-5
and 6-6, respectively, of Figure 2.
Figures '7 and 8 are perspective detail views.
Referring now to the drawings by distinguish
ing reference numerals, it will be observed that
50 the main or body unit is denoted by the numeral
9. This is preferably constructed from metal and
may be said to be of general U-shaped form in
cross-sectional dimension. It includes a flat
platen-forming plate or base I0 having spaced
55 parallel depending longitudinal side ?anges II
ately arranged offset shank to accommodate the 10
hand-grip I8. Finally, the numeral I9 designates
a screw-threaded hole to accommodate the bind
ing screw 20 which serves to hold the gauge 2|
in place. The gauge is shown to advantage in the
perspective view in Figure 8 and comprises a 15
simple block-like slide having a slot 22 to accom
modate the clamping or binding screw 20. Then,
too, it is provided on one longitudinal edge with
an outstanding right angularly disposed lug 23
which underlies the guard ?nger 24. The guard 20
?nger itself overlies the plate I0 in spaced par
allelism as shown to advantage in Figure 5. Thus,
this stabilizing lug 23 is interposed between the
?nger and the base plate. It serves to stabilize
the guard and gauge permitting them to main- 25
_ tain proper alignment abreast each other.
The
guard ?nger is provided with a downturned at
taching tang 25 slotted as at 26 to accommodate
a binding screw 21 which threads into a hole
provided therefor in the downturned ?ange II. 30
The free end portion of the guard ?nger is pro
vided with a kerf or notch 28 which serves to
properly seat and stabilize the right angularly
disposed cutting blade I4. It is to be noted that
the attaching tang 25 rests against the shoulder 35
or abutment Iii as disclosed in Figures 1, 2, and 5.
Assuming that the parts are assembled as
brought out in Figures 1 and 2, it is evident, from
Figure 1, that the sheet of leather A is slipped
into the space between the base or platen-form- 4,0
ing plate I0 and the overriding guide and gauge
finger 24. The gauge 2I is set to regulate the
width of the edge or cutting B which forms the
so-called rawhide string to be used for weaving
and other braid work. Obviously, by catching 45
hold of the handle and holding the sheet A in
a vice or other stationary clamp, it is possible
to draw the knife along in a longitudinal direc
tion maintaining one edge of the sheet against
the gauge 2!. It follows, therefore, that these 50
parts may be regulated with respect to each other
to provide the desired spacing and to maintain
uniform width in the out.
It is to be pointed out that by having the slot
26 and the downturned attaching tang 25 of the 55
' 2

guide and guard ?nger 24, it is possible to vary
the parallelism of this ?nger to the plate to
take care of different thicknesses of material, as
is obvious.

It is thought that the description taken in con
nection with the drawings will enable a, clear
understanding of the invention to be had. There
fore, a more lengthy description is thought un
necessary.

While the preferred embodiment of the inven~
tion has been shown and described, it is to be
understood that minor changescoming within
the ?eld of invention claimed may be resorted
to if desired.

I claim:
1. A cutting tool of the classvdescribed com->
prising a base plate having a, sheath, a ‘cutting’
shoulder, and a binding screw to maintain said
slotted tang adjustably in place.
2. In a sheet material stripping tool of the class
described, a body including a work resting plate
having down-turned spaced parallel longitudinal 5
?anges, a shank, and a hand grip carried by said
shank, one of said ?anges being slotted to provide
a blade accommodation and receiving sheath, a
guard ?nger overlying said plate in spaced par
allelism and provided at one end with a right 1O
angularly disposed attaching shank, said attach
ing shank being adjustably connected with the
adjacent ?ange, a slotted-block-like gauge ele
ment slidably resting on said plate, one edge
thereof being in abutting contact with the ad 15
jacent edge of that portion of the guard ?nger
over-lying said plate, said gauge element being
blade mounted adjustably in said sheath, said ' provided on said one edge with 2, lug interposed
plate being further provided with a depending

?ange shouldered at one end, a guard ?nger dis- '
screw carried by said plate and independent of 20
said guard ?nger and inserted through the slot
in said gauge element.
