Forrest Mfg. can create a blade for a single customer, a particular purpose, or a difficult substance -- including wood, plastic, brushes and more. For more than 60 years, Forrest saw blades have been meeting the challenges of evolving materials and machinery, and its design process includes sharing ideas based on years of accumulated knowledge and superb execution, research into the physical attributes and abilities of blades, and in some cases, producing prototypes, the company says.
