1. 1 . A dual hook device comprising: a) a grab hook having an open cradle; b) a sling hook having a closed cradle; wherein the grab hook and the sling hook are aligned and fixedly connected linearly through their bend centers head to toe with the grab hook and sling hook cradles either facing the same way or facing 180 degrees apart aligned and wherein the sling hook is directly connected to the bend center of the grab hook; and wherein the bend centers are centers of each rounded sections of the cradles; c) wherein a chain connector is positioned fixedly on a head of the grab hook and the sling hook is positioned on a toe of the grab hook, and wherein the chain connector is connected linearly through the bend centers of the grab hook and the sling hook cradles and lays planar with respect to the grab hook and the sling hook; wherein the sling hook comprises a head and a toe; the toe of the sling hook fixedly connected to the head of the grab hook; and wherein a centerline passes through centers of the heads and the toes of the sling hook and the grab hook and a center of the chain connector.

The copyright owner has no objection to the reproduction by anyone of the patent document or the patent disclosure as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all copyright rights whatsoever. BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a device consisting of both a grab hook and a sling hook forged to form one device for the purpose of hooking chains, ropes, cables, lifting heavy objects, and the like. Description of Related Art The use of different types of hooks is standard industry practice when used in applications such as lifting, logging, and moving heavy objects. These hooks are also used as cargo securement hooks used to secure heavy loads onto trucks, trains, and ships when transporting goods. A grab hook is a type of chain shortening or choking hook that's designed to grab a single link of chain for which it is being used with. These hooks are designed for overhead lifting and cargo securement applications. Grab hooks offer a unique design due to their narrow throat opening and can have a cradle or groove at the bottom of the throat. A chain, rope, or the like, is attached to an object and once secured; the chain or rope is attached to the open cradle or groove at the base of the grab hook. A sling hook is a type of lifting hook that's characterized by the use of a retainer latch and is frequently used in overhead lifting applications. Rather than featuring a narrow throat design as described with the grab hook, the sling hook features an open bowl design. All sling hooks have a safety latch that is used to secure the chain, rope or the like inside the bowl in slack conditions. The retainer latch on sling hooks consists of a long, solid metal bar. The retainer latch can be opened by pressing inward on it. To wrap the end of a chain or rope around a sling hook, for instance, you can simply press the chain or rope against the retainer latch. With that said, retainer latches only offer a one-way action. The retainer latch is designed to maintain the chain or rope within the confines of the bowl if the rigging presses against it after being installed. The retainer latch is not designed to withstand any load seen by the sling hook. The main difference between grab hooks and sling hooks is that the former doesn't have a retainer latch, whereas the latter does have a retainer latch. There are several different types of grab hooks, some of which include clevis and eye type connections. Regardless, all grab hooks have an open design without a retainer latch. Sling hooks, conversely, have an open bowl design with a retainer latch. They are also available with a clevis or eye type connection. Each of these hooks come in different sizes. Depending on the chain size being used and how the load is being lifted, a different type and size of hook would be selected. It is normal for individuals using such hooks to have both grab hooks and sling hooks in their toolbox in order to be prepared for all situations. BRIEF SUMMARY OF THE INVENTION The present invention relates to the discovery that if a grab hook and a sling hook used for chains, ropes, cables, lifting heavy objects, and the like are connected linearly with the hooks facing the same direction or 180 degrees aligned, there would not be a need for having multiple versions of hooks. One additional advantage is that while there is a hook on one side being used, the other hook can be used ergonomically as a handle which prevents fingers from getting caught in the hook being used, adding an advantage that is not in use of individual hooks. A single dual purpose hook device can avoid the problems described above. Accordingly, in one embodiment, there is a dual hook device comprising: a) a grab hook having an open cradle; b) a sling hook having a closed cradle;i. wherein the grab hook and the sling hook are aligned and connected linearly through their centers head to toe with the grab hook and sling hook cradles either facing the same way or facing 180 degrees apart aligned; and c) wherein a chain connector is positioned on the head of the grab hook and the sling hook is positioned on the toe of the grab hook. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a grab hook and a sling hook joined together head to toe. FIG. 2 is a perspective view of the grab hook and the sling hook attached head to toe, with the bowl facing the same way. DETAILED DESCRIPTION OF THE INVENTION While this invention is susceptible to embodiment in many different forms, there is shown in the drawings, and will herein be described in detail, specific embodiments with the understanding that the present disclosure of such embodiments is to be considered as an example of the principles and not intended to limit the invention to the specific embodimen
