[TheForge] Krause/Nazel type air hammer

[Larry and Pat Brown]

I think the timing of the opening valves in relation to each other would be 
more important than the shape. Why would the shape make that much of a 
difference? Wouldn't the air flow be more important than the shape of a 
small crescent or small rectangle?
