Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to pliers, and more particularly to pliers with a tool head that has colored surfaces formed on the tool head for identification. 
   2. Description of Related Art 
   With reference to  FIG. 8 , a conventional pair of pliers comprises a head ( 50 ), a handle ( 60 ) and plastic sleeves ( 62 ). The head ( 50 ) is composed of a pair of jaws. The handle ( 60 ) is composed of a pair of grips formed respectively with the jaws. The plastic sleeves ( 62 ) are mounted respectively on the grips of the handle ( 60 ). The head ( 50 ) of conventional pliers is usually made of metal and is either blacked or natural. Therefore, the head ( 50 ) of conventional pliers are either the original color of the metal or a blacked color. Consequently conventional pliers are unattractive, have only one color and do not have any features that can be used for identification. When many similar conventional pliers are mixed together, individual types or brands of conventional pliers are hard to distinguished from each other. Therefore, conventional pliers do not have either visual or the identification features to promote sales or make pliers of different brands uniquely identifiable. 
   The present invention has arisen to mitigate or obviate the disadvantages of the conventional pliers. 
   SUMMARY OF THE INVENTION 
   The main objective of the present invention is to provide an identification capability and attractive features to pliers. 
   Pliers in accordance with the present invention have heads with colored surfaces to enhance the attractiveness of the pliers and provide an identification feature. 
   Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   With reference to  FIG. 1 , a first embodiment of pliers ( 10 ) in accordance with the present invention are made of metal and comprise of a handle ( 11 ), a head ( 13 ), a rivet ( 15 ), at least one colored layer ( 17 ) and optionally, plastic sleeves ( 16 ) on the handle ( 11 ). 
   The handle ( 11 ) is a pair of grips (not numbered), and the head ( 13 ) is a pair of jaws (not numbered). The head ( 13 ) has an exterior surface. The jaws are integrally formed with and extend from the grips respectively to form two complementary half bodies (not numbered) of the pliers. The half bodies are pivotally connected to each other by pivotally attaching the rivet ( 15 ) at a joint between the grips and the jaws. Optionally, a plastic sleeve ( 16 ) is applied to each grip of the handle ( 11 ) to aid in holding the pliers. In the first embodiment, a colored layer ( 17 ) is attached to the exterior surface of the head ( 13 ) at the joint around the rivet ( 15 ) on the pliers. The colored layer ( 17 ) is selectively formed on the pliers by coating, sandblasting, bonding, etc. and is at least one color to make the pliers vivid, attractive and uniquely identifiable. 
   With further reference to  FIG. 2 , a second embodiment of pliers in accordance with the present invention has a colored layer ( 17 ) formed on the exterior surface of the head ( 13 ) in areas complementary to the first embodiment. The colored layer ( 17 ) is attached to the distal portions of the jaws of the head ( 13 ). 
   With reference to  FIG. 3 , the pliers are molded with excess metal in desired areas of the head ( 13 ), specifically the areas to which the colored layer ( 17 ) is to be attached. After pliers are molded, the pliers have smooth surfaces, and metal in the desired areas etched or machined to create rough surfaces to which the colored layers ( 17 ) are applied. The etched or machined areas are recessed so the colored layers ( 17 ) fill the areas and are flush with adjacent areas of the pliers after attaching the colored layers ( 17 ). 
   With reference to  FIG. 4 , a third embodiment of pliers such as side-cutters ( 20 ) in accordance with the present invention are made of metal and is composed of a handle ( 21 ), a head ( 23 ), a rivet ( 25 ), at least one coloring layer ( 27 ) and optionally, plastic sleeves ( 26 ) on the handle ( 21 ). 
   The handle ( 21 ) is a pair of grips (not numbered), and the head ( 23 ) is a pair of jaws (not numbered). The head ( 21 ) has an exterior surface. The jaws respectively have a distal portion (not numbered), a middle portion (not numbered), teeth (not numbered) and a cutting edge (not numbered) and are integrally formed with and extend from the grips respectively to form two complementary half bodies (not numbered) of the pliers. The teeth are formed on the distal portions of the jaws to hold objects. The cutting edges are formed on the middle portions of the jaws adjacent to the teeth to cut objects. The half bodies are pivotally connected to each other by pivotally attaching the rivet ( 25 ) at a joint between the grips and jaws. Optionally, a plastic sleeve ( 26 ) is applied to each grip of the handle ( 21 ) to aid in holding the pliers. A colored layer ( 27 ) is attached to the exterior surface of the head ( 23 ) at the joint around the rivet ( 25 ) on the middle portion of the jaws of the pliers. 
   With further reference to  FIG. 5 , a fourth embodiment of pliers in accordance with the present invention has a colored layer ( 27 ) formed on the exterior surface of the head ( 23 ) in areas complementary to the third embodiment. The colored layer ( 27 ) is attached to the distal portions of the jaws of the head ( 23 ). 
   With reference to  FIG. 6 , a fifth embodiment of pliers such as needle nose pliers ( 30 ) in accordance with the present invention are made of metal and is composed of a handle ( 31 ), a head ( 33 ), a rivet ( 35 ), at least one colored layer ( 37 ) and optionally, plastic sleeves ( 36 ) on the handle ( 31 ). 
   The handle ( 31 ) is composed of a pair of grips (not numbered), and the head ( 33 ) is composed of a pair of jaws (not numbered). The head ( 33 ) has an exterior surface. The jaws respectively have a distal portion (not numbered), a middle portion (not numbered), teeth (not numbered) and a cutting edge (not numbered) and are integrally formed with and extend from the grips respectively to form two complementary half bodies (not numbered) of the pliers. The teeth are formed on the distal portions of the jaws to hold objects. The cutting edges are formed on the middle portions of the jaws adjacent to the teeth to cut objects. The half bodies are pivotally connected to each other by pivotally attaching the rivet ( 35 ) at a joint between the grips and jaws. Optionally, a plastic sleeve ( 36 ) is applied to each grip of the handle ( 31 ) to aid in holding the pliers. A colored layer ( 37 ) is attached to the exterior surface of the head ( 33 ) at the joint around the rivet ( 35 ) on the middle portion of the jaws of the pliers. 
   With further reference to  FIG. 7 , a sixth embodiment of pliers in accordance with the present invention has a colored layer ( 37 ) formed on the exterior surface of the head ( 33 ) in areas complementary to the fifth embodiment. The colored layer ( 37 ) is attached to the distal portions of the jaws of the head ( 33 ). 
   Since the pliers in accordance with the present invention have different colored layers formed on the head, the pliers have a vivid feature to catch consumers&#39; attention. Additionally, the colored layer of multiple colors can be designed in different patterns for different brands or kinds of pliers so the pliers can be easily identified 
   Although the invention has been explained in relation to its preferred embodiment, many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
