Marshalltown 
Focusing on quality and commitment to excellence for over 100 years, the Marshalltown Company has grown to become one of the world’s largest manufacturers of masonry and related hand tools. Marshalltown features a quality line of brick tools that range from hundreds of different trowels, pointers, jointers, chisels, and more!
The Marshalltown Premier Line represents the top of the line tools. These tools are intended for the true professional who works in their particular trade all day, every day, where hand tools have to stand up to heavy, daily use. A third line, Quality Line Tools or QLT by Marshalltown, was established to offer value-priced quality for professionals. Marshalltown also expanded into a new market by introducing a do-it-yourself line for the homeowner.
