Field RepairSource Ultimate Combat pg. 101
You can repair your broken weapon or armor to serviceability even without the benefits of artisan tools.
Prerequisites: Craft 4 ranks.
Benefit: If you are trained in a Craft skill appropriate to a broken item, you can repair that item with no raw material cost and no penalty on your Craft skill check for using improvised tools. If you spend a day, the item regains 1 hit point plus one-quarter of its original hit points. Alternatively, if the item gained the broken condition because it is a firearm that has misfired or a siege engine that suffered a mishap, or has the broken condition because it has the fragile weapon quality (or some similar quality), you can make a Craft check with the DC it takes to craft that item (see Table 2–2, below). If the check succeeds, the item loses the broken condition.
Normal: Improvised tools impose a –2 penalty on Craft checks. Items require raw materials to repair.
