FISHING KNIFE Application led June 30, 1931. Serial No. 547,961.

This invention relates to cutlery and more particularly to a pocket knife intended for use as a fishing knife. V

One object of the invention is to provide a pocket knife having a handle and a large blade for use when cutting bait, the handle being equipped with a sharpeninol stone by means of which fish hooks which have become dull may be easily sharpened.

Another object of the invention is to so form the handle that the sharpening stone may be firmly mounted in a seat in the hack of the handle and supported therein by resting upon the spring of the knife.

Another object` of the invention is to so form the seat and stone that the stone will be firmly held in place, but by loosening a side facing of the knife handle, the stone may be removed and a new one set in place when necessary.

The invention is illustrated in the accompanying drawing wherein:

Figure l is a View showing the improved knife in side elevation, Y

FigureI 2 is a longitudinal sectional view thro-ugh the knife,

Figure 3 in taken transversely through the knife along the line 3-3 of Figure 2, and

Figure e is a perspective view of the sharpening stone.

The frame of this knife is preferably formed from sheet metal of sufficient thickness to provide a sturdy handle. The blank i from which the frame is formed is folded 5 longitudinally intermediate its width thereby forming a frame which is U-shaped in cross section as shown in Figure 3 and has side walls l and a back wall 2 which may be referred to as a rear edge wall.

The walls l and 2 define a pocket 3 to receive a blade. 4 which extends substantially the full length of the pocket when closed and is pivotally mounted by a pin 5 which extends through an opening 6 formed in the heel 7 of the blade and through aligned openings formed in the side walls l.

A spring 8 is employed to yieldably hold the blade in either a closed or opened position and the spring extends longitudinally in the pocket where it is secured by pins 9 and l0. It should be noted that the portion of the spring between the pin 9 and the rear end of the handle has contacting engagement with the inner face of the wall 2. After the spring has been secured in the pocket the wall 2 and theadjacent -faceof the spring Sare ground or otherwise cut to forni a pocket or seat 1l which has undercut end portions as clearly shown in Figure 2.l Attention fis called to the fact that this seat extendsthe full width of the wail 2 and is of'such depth that it extends downwardly into the side walls as shown in Figure 3 and also into the portion of the spring which bears against the inner face of the rear wall. U5 By this arrangement a sharpening stone l2 which corresponds in width to the seat and has beveled ends 13 may be slid transversely into the seat with its beveled ends tting into the undercut end portions of said '70 seat. Vhen it is in place the stone will rest upon the spring and since its beveled ends are overlapped as shown in Figure 2 it will be prevented from dropping out vof the seat. The stoneV is of greater thickness than the seat and therefore it will project outwardly from the same and when a fish hook needs sharpening it may be engaged in agroove 14; formed in the outer face ofthe stone` and reciprocated longitudinally therein until a sharp point is restored.

The facings l5 whichare disposed against the outer faces ofthe side walls l of the frame areV secured thereto by the pins 5 and l0 and by referring to Figure` 3 it will be 85 seen that these facings overlap side faces of the stone and thereby serve to prevent the sto-ne from sliding transversely out of the seat.V rl`herefore it is not necessary to employ cement or securing'pins in order to firmly 90 hold the stone in its seat. It will be obvious that the' stone must be fitted into the seat before one of the facings is secured and it will also be readily apparent that by releasing one of the facings this facing may be swung about the pin 5 and a sto-ne which has become worn out may then be easily slid transversely out of the seat and a new stone set in place.

I havetherefore provided a iishing knifeV which is very7 strong in construction and has associated therewith a stone upon Which fish hooks may be sharpened.

It will be understood that use of the stone is not limited to knives having a handle of the specific construction shown but may be applied to any knife in Which the handle has a rear edge portion adapted to be cut to form a stone receiving seat and a spring serving as a support for the stone.

IVhat is claimed is:

l. A cutting tool handle including a frame having a back Wall recessed to form a seat extending longitudinally thereof, a spring bridging said seat, and a. sharpening element engaged in said seat and resting upon said spring.

2. A cutting tool handle including a frame having a back Wall recessed to form a seat extending longitudinally thereof, a spring bridging said seat, a sharpening element engaged in said seat and resting upon said spring, and side members secured to the frame and overlapping the side faces of said sharpening element to prevent the sharpen ing element from moving transversely out of the seat.

3. A cutting tool handle including a frame having a back Wall recessed to form a seat extending longitudinally thereof, a spring bridging said seat, a sharpening element engaged in said seat and resting upon said spring, the seat having undercut ends and the sharpening element having its ends bevelled and extending intor the undercut ends of the seat and its side faces exposed at sides of the seat, and side members secured to the frame and overlapping the side faces of said sharpening element to prevent the sharpening element from moving transversely out of the seat.

4. A cutting tool handle including a frame having a longitudinally recessed back Wall, a spring disposed at said back Wall and having a portion thereof cut away to form a seat registering with the recess in said back Wall, the ends of the seat and the end Walls of the recess being under cut, a sharpening element fitting in said seat and having its exposed surface projecting beyond the end wall and grooved and its opposite ends inclined to conform to the under cut ends of the seat and recess respectively, and side members secured to the frame and bearing against the sharpening element for retaining said sharpening element Within its seat.

In testimony whereof I aiiix my signature.
