We are Griffin Tool, Inc.

Griffin Tool, Inc., located in Stevensville, Michigan, specializes in the design and fabrication of trim dies for the die cast and foundry industries. Clients include companies producing autos, lighting, power tools, small gas engines, farm equipment, recreational vehicles, and office furniture. The 65-member team serves customers throughout the world.


At Griffin, the tool and die roots run deep. Louis Sahs worked in the industry for Pemco in Bridgman, Michigan and then later started Progressive Tool & Die. Greg Griffin apprenticed with his father-in-law, Louis, and worked for Progressive for many years. He later worked for Metal Processors before opening Griffin Tool, Inc. in 1988 with a partner who soon chose to pursue other endeavors. Greg and wife Chris raised a family in Stevensville, Michigan while running the family business.

Malcolm Cowan, Chief Executive Officer, began working for Griffin Tool in 1994 as an apprentice through Lake Michigan College. He and Jenny Griffin married in 1999, and both worked for Griffin Tool throughout the following decades. They acquired the business from Jenny’s parents in 2018, during the 30th anniversary year for the company. Jenny then assumed the role of Chief Financial Officer.


Daughter Lillian began working for the family business through a co-op program in high school, and upon graduation in 2021, joined Griffin Tool, Inc. as Office Manager and a fourth-generation family member to help lead the business.
