    Frank, all very true. The cheap blades have crap blanks and low grade (hardness and coarse TC grain) carbide teeth. They heat up, warp, dull quickly and are just a waste of time. No commercial enterprise would consider them. I operated a specialty plywood and panel business in Sydney for 13 years and did HEAPS of cut to size work on my Wadkin clone 12" table saw. I used Freud and CMT blades having them regularly sharpened. The attached video link shows how the diamond wheel only grinds the face of the tooth, as the sides are hollow ground. I would get maybe 15 sharpenings for a $130 blade. I still have about a dozen blades with little tiny teeth from all that grinding! I still use the same sharpening service, costs $20-24 per blade. Can't see why you would do it any other way...I guess casual users only have 1 blade...you must have at least 2 if not 3 of each cutting type to allow for 1 week turnaround ( I'm 140 km from Sydney). Freud (not the DIY Diablo range), CMT, Amana, Forrest are all high quality. If it costs $30 - 60, it's junk...think $80-150 and locate your local sharpening service by asking the local cabinetmaker. Once you cut with a REAL blade, you will never look back! Cheers guys
