The ?ange I2 is thickened This invention relates to an improved and novel hand tool for cutting sheetYmaterial; especially rawhide and leather, whereby to facilitate cut ting pregauged stringslto be used by saddle somewhat at one end and provided with a slot I3 forming an appropriate sheath to accommo 5 makers and cowboys, and the like. Admittedly, there is a long felt need existing a set screw I5 threaded into the so-called sheath. date the removable‘ and renewable cutting blade I4. Incidentally, the blade is held in place by 5 On the opposite ?anged end is an outstanding for the development and perfection of a satis- , portion laterally offset to de?ne a shoulder as 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. 30 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. 45 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 2,121,681 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. 10 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. 15 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 between the guard ?nger and plate, and a set ?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. posed above the work receiving side of said plate having a kerf atone end receiving the cutting edge of said blade, having a slotted attaching tang at the opposite end engageable with said JOSEPH A.
