These saws have to be the cheapest and by far the most cost  effective way to shape sandstone. I have two different sizes, a 300mm carbide  rod saw and a smaller 200mm diamond saw.  
                                          How do they work? 
                                    Unlike a usual saw blade that has a distinct cutting edge  with teeth, a rod saw blade is made up of a length of wire impregnated with  abrasive grit. This is incredibly useful as it allows the blade to cut in any  direction and means that angle and circular cuts can be made quite easily.  |

                  Why do I like using them?
                                          These hand saws don’t kick up huge clouds of dust or stone  chips, don’t make a huge noise and won’t cut into either you or the work bench  if you put them down without thinking. In short, I find working with hand tools  quite relaxing and a lot more satisfying that using power tools. 
                       
                      An added advantage is of course that they are dirt cheap. Each  of the saws cost me less than $20 all up which includes both saw frame and  blades. For the larger carbide blades, I can usually find replacements for  between five and eight dollars. As for the diamond blade, well, I don’t really  use it that often so the original blade is still going strong.  
                    Where to get them
                  I have tried looking online for them but overall, I just don’t think it’s worth it,  the price per blade is so low anyway that any savings made online are eaten up  by the need to pay postage. To this end, a trip down to the local hardware  store is a lot quicker and easier.                     |
