Customers are mixed about the melting of the saw. Some mention it worked perfectly, with no melting, jagged edges, or breakage. However, others say that the blade would heat up and burn the wood, shards come off very hot, and melt and imbed in plastic portions of the see.

Cut 20+ Sheets of Hardibacker and still going strong
I was building an outdoor kitchen and I needed lots of concrete board but the reviews on most of these blades where not great. Either very expensive or short life. I was skeptical but I went with this blade and was impressedI needed to cut....8x - 4x8 1/4 inch sheets of hardibacker10x - 3x5 1/4 inch sheets of hardibacker5x - 3x5 1/2 inch sheets of hardibacker.All boards required cutting and this one blade cut them all with ease. Even after all that cutting it cut just as smooth and clean as the first cut. See picture...lots of cuts needed. Wear glasses and dust mask this stuff is bad for your lungs
