Well, there isn’t any lore that would adress elven smiths in particular. We can talk a lot about Priests of Vaul, though that is an entirely different league and beside the point. Generally, one studies a craft from a very young age (relatively speaking) as reaching elven “bottomline” standard takes hundreds of years and eventual mastery even entire life.
Of course, some may point out Teclis who forged his own blade - after making an extensive research of Caledor Dragontamer’s work - without pretty much any previous experience. But that’s Teclis allright.
