Appreciation for "Tricks of the Trade" accuracy (minor spoiler)

[Banjo]

So if you do pass the speech check, you find out how the blacksmith gets his steel so hard. Basicaly quenching the steel twice. As a metallurgist I just want to say I appreciate the attention to detail in this quest because there is real science behind quenching twice without reheating past a certain point. Obviously some serious homework was done to get this detail right and I appreciate that.
