No the Smith has no actual weapons to sell but if you buy stuff like the pickax from her and go to your menu, select the Equipment option then click on Optimize
If you want to enjoy this game and not die of stress just use your CHEAT MENU, go to your menu options and select the HOTKEYS tab then look for CHEATS and set the HOTKEY as Enter (RETURN) and just like that you will be a GOD (if you're smart enough)
