I suppose that everyone is entitled to more than one opinion .... but for the same person to (first) post some math-heavy engineering blather ... then go on to extol cheap third-world imports ... and omit any consideration of metlalurgy or handle ergonomics ..... that person must be using the tools as paperweights
Ditto for the guy who carefully modified the handles of his pliers .... to make something that is readily available, from the factory!
