Usage & Description
Tinderbox is highly effective against flesh targets and especially at igniting them. However the fixed element and low ammo efficiency makes it unsuitable for general combat.
If A Train to Catch is active, a Tinderbox will drop after shooting the head of the snowman located in the southern area of Tundra Express, next to the vending machines. Once it is picked up or the mission is completed, it will not appear at this location again.
This is intentionally done by the developers in case the player has no incendiary weapon. Roland will state that he hid the Tinderbox for emergencies when it was mentioned.
The Tinderbox's damage is boosted by grenade damage bonuses.
A tinderbox is a small container containing flint, firesteel, and tinder (typically charcloth, but possibly a small quantity of dry, finely-divided fibrous matter such as straw), used together to help kindle a fire.
