The BikeHand tool that the OP is asking about is fine. For that particular tool it's got plenty of steel and is beefy enough that not much could go wrong with it. Maybe some experts will chime in to confirm or dispute this but I believe you need a deeper socket for the Octalink BB than the old square taper so make sure it's the deeper version which can be used for both. Tools that need a little more finesse in design such as cone wrench's where you need thinner but very strong steel and closer tolerances are a different story.
