Demolitionist

The Demolitionist is an NPC vendor that will spawn once the following criteria have been met:

 * You have an explosive in your inventory.

Once the Demolitionist has moved into a house, he will sell the following:

Note: As with all NPCs, right-clicking an item will allow multiple purchases rather than purchasing it one by one.

Trivia

 * The Demolitionist's appearance seems to be based on dwarves from many games, films and works of literature. He is significantly shorter than other NPCs and has a beard. Furthermore, his mining helmet, lantern, and the fact that he sells Explosives fits the trope of dwarves preferring underground environments. He and the Arms Dealer also seem to have a rivalry.
