The present invention generally relates to a multipurpose tool, and more specifically to a reconfigured hammer with an ergonomic design and additional functionality. Accordingly, the present specification makes specific reference thereto. However, it is to be appreciated that aspects of the present invention are also equally amenable to other like applications, devices and methods of manufacture.
A hammer is a tool with a weighted head attached or affixed to a handle that is swung to deliver an impact to a relatively small area of an object. Hammers have a wide variety of designs and are configured to accomplish a wide variety of driving, shaping, and breaking applications. Hammers are used every day in a wide variety of applications, especially by professionals. The traditional hammer design has an uneven weight distribution where most of the weight is located in the head of the hammer. This makes swinging more difficult and allows for less accuracy when striking a nail. It can be difficult to strike nails in various positions with optimal control and efficiency using a conventionally designed hammer.
The most commonly used hammer is the claw hammer. While many hammers only perform the driving or pounding function, claw hammers are additionally configured as a prying tool to pull things apart or remove nails. Thus, the claw hammer is a multifunctional tool that both hammers and pries. The curved claw hammer contains a double-sided head that lets you drive nails into surfaces using the hammer side and remove nails using the curved claw side of the head. This hammer is split and usually curved on the claw side forming a cleft for engaging a nail to be pulled out. The claw is generally rounded allowing for better leverage as the used pulls the handle. The hammer side of the head also is slightly curved to minimize marring the surface you are nailing. The flat side is used to pound nails in.
Claw hammers have been further modified to better perform many different functions. The straight claw hammer, also known as a ripping claw hammer, is used to dismantle items, including wood, tile and plastic. The hammer's claw is not curved and fits between boards and materials to separate them without the hassle of using another tool. Straight claw hammers are heavier than curved claw hammers. Traditional framing or ripping hammers feature a slightly curved, dull claw on the head designed for splitting wood in rough-framing applications. Framing hammers do not contain a curved head, which also leads to indentations in the wood or other surface you are nailing.
In this manner, the improved multipurpose tool of the present invention accomplishes all of the forgoing objectives, thereby providing an easy solution for overcoming the deficiencies of conventional hammers. A primary feature of the present invention is a hammer with an ergonomically correct design that offers ease of use for carpenters, contractors, plumbers, electricians, laborers, or anyone else that uses a hammer. The design enables users to operate the hammer with less manual effort than conventional hammers affording users the ability to strike nails at any angle with ease and accuracy. The new design of the present invention also features a redesigned claw that comes to a point for easy use and maximum efficiency in these various applications.

Thus, in other embodiments, any of the features described herein from different embodiments may be combined.
The present invention, in one exemplary embodiment, is a hammer with weight distributed substantially equally due to a curved handle and a heavily curved claw on the bottom. The uniquely designed tool allows users to swing it almost effortlessly due to the weight distribution between the bottom and the top. The bottom claw enables users to pull nails without the need for a nail puller or other additional tools in most scenarios.
The hammer is comprised of a solid piece of metal that forms a head of the hammer. The metal head is substantially hexagonal in shape and mildly rounded on all of the edges of the face. The head is not rounded or square like traditional hammers. The head may be compressed onto a wooden, fiberglass, solid metal construction, or composite shock absorbent handle and further secured with a grade eight double-sided sleeved screw or bolt in one embodiment. This helps hold the head in place on the handle without loosening. The handle may be aggressively curved.
The hammer may further comprise an additional claw built in or attachable to a bottom of the handle. The additional claw balances the weight of the hammer and allows the weight of the head to be lighter than that of a traditional hammer. The additional claw may be weighted and built as an internal shaft inside of the handle secured by steel belts to prevent it from being pulled out in one embodiment. In another embodiment, the additional claw may be configured with a sleeve that fits over a bottom of the handle with small teeth from front to back holding it in place. The additional claw may be also be further secured with a double sided screw similar to the grade eight double-sided sleeved screw or bolt used to secure the head of the hammer at the opposite end of the handle, or constructed of one solid piece that includes the head, handle and the claw.
The hammer may further comprise a pair of magnetic nail catches on a bottom and a top of the head. A top of the hammer may employ a straight claw with built-in nail puller configured to get flush with a wall or corner to engage a nail. The bottom claw allows for weight distribution and allows users to get into tight places with additional leverage.
