Who We Are

Our History


Our founding company, StoneAge Tools emerged in 1979 when co-founders John Wolgamott and Jerry Zink (former classmates at the Colorado School of Mines) developed a new self-rotary waterjet nozzle in their Durango, Colorado garage. Originally intended for the mining industry “to cut holes in rocks,” the newly created nozzles eventually changed the way heat exchangers were cleaned. The founders’ passion for research and development bred a culture of product innovation that has transformed the waterblasting industry over the past four decades. 
This passion for product leadership and commitment to designing new equipment brought StoneAge Tools to the forefront of the movement towards hands-free and automated waterblast equipment. New state-of-the-art, in-house testing facilities allow a dedicated engineering team to continue pushing the boundaries of design and technology. By partnering with industrial cleaning contractors, StoneAge Tools engineers gain unique insight to guide their design of automated systems that advance safety and productivity for a wide variety of waterblasting applications.  


Stemming from that very ingenuity, Warthog Nozzles emerged in 1989 as a spinoff to bring controlled rotation technology to the sewer and drain cleaning industry. Differing from StoneAge Tools through a lower pressure design, Warthog Nozzles provide a wide range of premier sewer and drain cleaning tools to customers around the globe.  


To bolster development of robotic and automated solutions, StoneAge Holdings acquired IoT product development firm, Breadware, in spring of 2020. Based in Reno, Nevada, Breadware specializes in helping industrial OEMs build and launch smart products and connected solutions.


Breadware acquired software provider, Medium One, in spring of 2022 to solidify its position as a true, end-to-end development partner. Now an integral piece of Breadware’s brand and service offerings, this software is known as the Rise software platform.  


StoneAge Tools formalized the acquisition of long-time competitor, Terydon. Uniting personnel and resources together as one business, customers throughout the department of defense and industrial cleaning can now benefit from intentional combination of leading technologies and equipment systems.
