Wild Bill,
I do not mean any disrespect, you sound like a man who I could set and watch work a for hours, blacksmithing always intriged me, I am just not real good at it. But on the blade topic, I sell a lot of blades in my business and mower manufacturers may put bids out on their blades for the lowest price, but they also have very, very stringent specs they must meet to get that contract. do to the impact of blades, a manufacturer uses a steel pipe test on their blades to see how they hold up under impact at 18,000 feet per minute, too soft, they are junk, too hard, they become lawsuit material. As for balancing blades, all blades are in balance when they leave the factory, They know what kind of steel they are using, know the weight of the steel they are using, the blades are all run in production, cut the same out the same steel, sharpened the same way every time. Some may come out of balance, but now very often. Then when you put your blade on your lawn mower, the first time you mow with it, it is out of balance, the grass builds up on it in a differant place on each blade. So, the one thing I do know, blades for mowers are probably the most critically checked item on any mower, just due to the fact if they are made cheap, there are a hundred lawyers out there ready to sue someone. Do to the insurance costs to manufacture and sell blades, there are only 4-5? blade manufacturers in the US. A lot of OEMs buy their blades from the same vendor.
