I think it is great that Anet has made the infinite gathering tools account bound as many requested. For those of us with alts, the cost of a full set of tools for each toon was exorbitant so many of us chose not to buy them.
I am also gratified that Anet showed a lot of class in being willing to refund gems to those who bought multiple sets for their multiple toons.
That being said, I hope that Anet will make these tools an unlockable item that you buy once and can then equip as many as you like on all your toons. As it is you still have to buy multiple tools or keep switching the tools between toons which is a hassle that doesn’t need to be there, particularly given the high cost of a full set and the fact gathering tools are cheap or free in most games.
