I'm thinkin' you young guys are hooked on political correctness. I'm well into my 80's boys and have been an expert and certified welder, mechanic and engineer for a long long time. I'll put my rebuilt blades up against any, new or old, nobody has to worry about anything flying anyplace.
I've restored scores of old cars, still have 7 of them, you can drive them anywhere anytime and no worries about the rod caps, they fit and they work. I get enjoyment out of beating the system, I don't spend money on things that can be fixed or rebuilt, my bank account proves it. Aircraft engines & airframes, cars, lawn mowers, motorcycles, nobody has ever complained and that's in the record, our ol' 149 just another on the list.
My advice guys ... get your fingernails dirty.
