Built to Destroy

 is a Trait which only appears in Fallout: New Vegas.

Though it says that "The flamer that burns..." it is not directly referring to the Flamer weapon; instead it is subsituting "flamer" for "candle" in a common proverb (also a reference to the "slo-burn" unique flamer from Fallout3 which consumed double the fuel and degraded slightly faster to increase the magnitude of the burn DPS). By choosing this trait, you are increasing the chances for your weapon to do critical damage in combat as well as increasing the rate at which it will eventually break.

Do not be misled by the apparent disparity in numbers; a 15% increase in wear-and-tear is fairly modest, essentially meaning that you'll do the same wear in 7 shots that a player without this trait would do in 8 shots, while a 3% increase in crit chance can have significant effects on damage output (particularly with weapons with x5 critical multipliers) considering that it is fairly difficult to raise critical chance. However, the additional loss of weapon condition can be an aggravating effect on expensive or hard to find weapons; therefore it is recommended that characters possessing this trait aim to pick up the Jury Rigging perk as soon as possible.
