Alas, the only information stored is what item it is (ID), how much there is (quantity), and the prefix.
However, that can be done via plugins, and I've made a plugin for TerraPatcher.
So you would run the program to patch Terraria.exe with plugin support (you probably want to untick everything but "plugin support" and clear the "persistent buff" list), then you would drop the plugin source file,
https://gist.github.com/YellowAfterlife/1edaa4060191823ee366 (click "View Raw" and save-as)
to the Terraria/Plugins (TerrariaPatcher should make that directory)
and then you can make a "ItemConf.ini" (if you don't, a empty one will be made on game start) and add stuff like this to it
Code:
[item426]
name=Breaker Blade Plus
damage=78
usetime=20
scale=1.3
knockback=12
(426 is Breaker Blade' item ID, you can find them on wiki or Terranion)
