A new and improved multi-function hand tool with multiple purpose interchangeable utility heads is provided. This multi-function hand tool with multiple purpose interchangeable utility heads would have a utility head block with two utility head accepting portions providing for maximum versatility and result in a compact tool for convenient transportation and storage. The utility head block is solid to better absorb force upon impact, maintain design integrity and provide for proper weighting of the tool when used as a hammering or striking tool. The attachment mechanisms are designed to maintain integrity and optimum safety, even after consecutive, frequent usage. The utility head block is also designed to safely accommodate different hammer handles for various usage demands or if handles become damaged, thus extending the usable life of the tool. The present invention enables a user to readily selectively change the configuration of the tool that he is using to adapt the tool to various demands of an application by providing interchangeable multiple purpose utility heads and handles which quickly and safely attach to a single utility head accepting block. The overall size, weight and cost of the tool is much less than comparable conventional hand tools that it would replace. Interchangeable utility heads would be inserted into the utility head block by means of a guide shafts and held in place by a combination of a friction fit and ball/spring assembly. The handle would be held in place with the aid of wedges and a bore and tube assembly providing two safety mechanisms to prevent unexpected release of the handle during use. The nature of the attachment configuration does not require extremely high tolerance manufacturing or a large number of parts and so the production of the device would be relatively economical and the simplicity of design would result in low maintenance costs.
