The Ultimate Tools UTD12B 12″ Shammer is a purpose-built multi-function hand tool designed to combine two commonly used tools—the adjustable wrench and hammer—into one convenient, heavy-duty unit. Developed with the demanding requirements of the mining industry in mind, the Shammer is equally suited to construction, mechanical maintenance, plumbing, farming, general trade work and DIY applications.

By combining an adjustable wrench and striking surface in a single tool, the UTD12B can help reduce the number of individual tools a worker needs to carry around a job site. This makes it particularly useful for maintenance personnel and tradespeople who frequently need to adjust fasteners and then apply controlled striking force during the same task.

The Shammer’s 12-inch format provides a useful combination of reach, leverage and portability, making it well suited to larger fasteners and general heavy-duty maintenance work. Its multi-purpose design is particularly beneficial in environments such as mining and construction, where carrying fewer tools can improve convenience and reduce equipment clutter.
