A final object thereof is to provide a cutting implement with rotary means on the handle thereof, designed, when actuated, to space apart the several parallel knife blades variably so that slices of different thicknesses .may be cut.

`l/Vith the above and other objects the invention consists in the `arrangement,combination and details in the drawing and specification, and then more particularly pointed out in the appended claim. n

In the drawing, wherein similar reference characters designate similar out the respective views,

Figure l is a longitudinal section through niy invention;

Figure 2 is a top plan View thereof,

Figure 3 is a side elevation thereof7 Figure 4 is a cross sectional view of the complete device,

Figure 5 is an end elevation of the device looking from the rear,

Figure 6 is a cross-sectional View taken through the slidable members of the device.

I provide a construction of knife wherein the plurality of blades are transversely ad` justable in a simple manner. A rectangular case 19 provides the handle for the knife and secured therearound and secured upon the flat sides thereof are the four preferably Wooden segment shaped pieces 20 secured by A further object thereof is to provide a` of construction disclosed parts through-V threaded pins or thelikefastenersl 2li-'to the flat sides of this casef Inside of this caseare slidably mountedl the channel-shaped cutters.` :One cutterisconrposed of the vertical knife edged :Wall 22 Whose Vparallel right-angular lateral langes;
