I read here details about various private people making homemade blades. This seems to be a legal loophole in ITTF rules. Because I was surprised to hear there is some sort approval process for rubbers but not for blades. In fact I did not even know what a blade was and they were sold separately.
It is confusing then as to why rubbers must be approved but not blades. Does this not hurt manufacturers who pump money into the sport ? Maybe I am playing devil's advocate but I would like to hear both sides of this issue, if I am not way out of line
