A dual headed hammer is a hammer with special features for framing and finishing applications. A first head of the hammer has a smaller head and face for finish carpentry applications, and may have a gridded-face to prevent nail slippage. A nail-extractor is located midway between the head and the handle. The opposite end of the hammer has a larger second head for framing applications. Additionally, the larger second head has a plurality of nail holders, complete with magnets, on the top and lateral sides of the second head. The handle is sized such that the total length of the invention is exactly 17.5 inches to aid in construction of walls that use 2×4 studs, 16 inches on center.

What is claimed is: 1. A dual headed hammer comprising: a linearly elongated handle having an upper portion opposite to a lower portion, said handle having measurement etchings measuring 1.5 inches in length from a base of said handle and extending to an uppermost ringed etching, said handle measuring 16.75 inches in length from a top surface of said hammer to a lower surface for quickly and accurately determining placement or location of a wall stud; and a dual head receiving and physically impinging said upper portion of said handle in a receiving orifice, each one of said heads for driving a nail. 2. The dual headed hammer of claim 1, wherein said handle includes a curvilinear form at said base of said handle, said curvilinear form curved toward a posterior of said hammer, said curvilinear form ergonomically shaped to reduce stress and injury to a user's hands, wrists and arms. 3. The dual headed hammer of claim 1, wherein said dual head comprises: a first head formed at an end of said dual head having a first face for striking a head of a nail; a second head formed at an end opposite to said first head and having a second face for striking a head of a nail; a plurality of nail holders formed in said second head. 4. The dual headed hammer of claim 3, wherein said first head has a diameter measuring between 0.375 inches and 1 inch, said first head sized to perform finish carpentry applications, thereby preventing denting and dinging of the finish material. 5. The dual headed hammer of claim 3, wherein said first face comprises a heat-treated grid surface, said grid surface providing a frictionally enhanced surface resistant to slipping when said first face strikes said head of said nail. 6. The dual headed hammer of claim 3, wherein said first face comprises a smooth surface not imparting a gridded imprint when said first face strikes a surface. 7. The dual headed hammer of claim 3, wherein said second head has a diameter measuring between 0.75 inches and 2 inches, said second head sized to perform framing applications, thereby providing the weight and force necessary to drive large framing nails. 8. The dual headed hammer of claim 3, wherein said second face comprises a heat-treated grid surface, said grid surface providing a frictionally enhanced surface resistant to slipping when said second face strikes said head of said nail. 9. The dual headed hammer of claim 3, wherein said second face comprises a smooth surface, said smooth surface not imparting a gridded imprint when said second face strikes a surface. 10. The dual headed hammer of claim 3, wherein said plurality of nail holders comprises: a top nail holder having an arcuate channel formed in a top surface of said second head, said top nail holder sized to accommodate large nails; a first lateral nail holder having an arcuate channel formed in a lateral surface of a second head, said first lateral nail holder sized to accommodate small nails; and a second lateral nail holder having an arcuate channel formed in a lateral surface of said second head, opposite to said first lateral nail holder, said second lateral nail holder sized to accommodate intermediate nails. 11. The dual headed hammer of claim 10, wherein said top nail holder, said first lateral nail holder and said second lateral nail holder each further comprise a magnet housed within said arcuate channel, said magnet providing means for securely holding a nail in place while a user strikes a nail. 12. The dual headed hammer of claim 1, wherein said dual head further comprises a nail extractor, said nail extractor formed in a top surface of said dual head and adjacent to said first head, said nail extractor for extracting impaled nails. 13. The dual headed hammer of claim 12, wherein said nail extractor comprises: a first section; a second section, said second section and said first section converging at an acute angle; a third section, said third section and said second section converging at an obtuse angle; a fourth section, said fourth section and said third section converging at an acute angle, said fourth section and said first section converging at an obtuse angle; said first section, said second section, said third section, and said fourth section forming a diamond shaped nail extractor. 14. The dual head hammer of claim 1, wherein said receiving orifice is an elliptically shaped orifice formed in said dual head, said receiving orifice physically receiving and impinging said upper portion of said handle. 15. A dual headed hammer comprising: a linearly elongated handle having an upper portion opposite to a lower portion, said handle having measurement etchings measuring 1.5 inches in length from a base of said handle and extending to an uppermost ringed etching, said handle measuring 17.5 inches in length from a top surface of said hammer to a lower surface for quickly and accurately determining placement or location of a wall stud; and a dual head receiving and physically impinging said upper portion of said handle in a receiving orifice, each one of said heads for driving a nail. 16. The dual headed hammer of claim 15, wherein said dual head comprises: a first head formed at an end of said dual head having a first face for striking a head of a nail; a second head formed at an end opposite to said first head and having a second face for striking a head of a nail; a plurality of nail holders formed in said second head. 17. The dual headed hammer of claim 16, wherein said plurality of nail holders comprises: a top nail holder having an arcuate channel formed in a top surface of said second head, said top nail holder sized to accommodate large nails; a first lateral nail holder having an arcuate channel formed in a lateral surface of a second head, said first lateral nail holder sized to accommodate small nails; and a second lateral nail holder having an arcuate channel formed in a lateral surface of said second head, opposite to said first lateral nail holder, said second lateral nail holder sized to accommodate intermediate nails. 18. The dual headed hammer of claim 15, wherein said dual head further comprises a nail extractor, said nail extractor formed in a top surface of said dual head and adjacent to said first head, said nail extractor for extracting impaled nails. 19. The dual headed hammer of claim 18, wherein said nail extractor comprises: a first section; a second section, said second section and said first section converging at an acute angle; a third section, said third section and said second section converging at an obtuse angle; a fourth section, said fourth section and said third section converging at an acute angle, said fourth section and said first section converging at an obtuse angle; said first section, said second section, said third section, and said fourth section forming a diamond shaped nail extractor.
