You gain a point in your Strength score.

Using a set of Smith's Tools on a weapon over the course of a long rest, you can repair or improve the weapon. Repairing a weapon this way costs a quarter of the normal material cost.

You can improve a single weapon, with 10gp's worth of materials, in only one of the following ways;

• Sharpened Blade. The weapon deals an additional 1d4 damage.
• Reinforced Core. The weapon grants 1 additional AC to the creature wielding it.
• Secure Handle. When making attack rolls with the weapon, roll an additional 1d4.
• Magic Coating. The weapon's damage becomes magical.
