The KA75 Power Hammer

Grant Sarver of Tacoma WA invented the KA75 Striking hammer in 1995. Production was moved to Wisconsin in 1998 to be more centrally located in the U.S. for low cost shipping. An invention that began as a sketch on a napkin has continued to be bought by hobby and professional smiths & blacksmiths in the US and Europe. The KA is a tireless helper. The rugged construction and low-tech simplicity of the machine have created a loyal following of owners.

The unconventional design of the KA75 has surprised many first time observers. It is compact and has only one foot-lever to operate it. There is nothing to adjust, yet the machine can hit a soft or hard blow, hit once or repetitively. The air cylinders serve as structure and motion in the design. The rods point downward which keeps dirt and scale away from the seals. Most parts are off-the-shelf components for easy replacement.
