          The design of this saw frame is absolutely rigid, minimizing saw

          the ends of the blade are inserted into small holes and clamped

          frame. Much simpler! These saws are made in the USA using only
        
        
          USA-made parts including the screws. The saws use the same
        
        
          small blades as the hobby-quality jeweler’s saws.
        
        
          These saw frames cost $47 each compared to about $15 for
        
        
          the standard hobby-quality saw frame. I think that the differ-
