Goblin army knife

It’s not stylish and it’s useless as a weapon, but no sensible goblin warrior marches without this tool-of-all-trades. The goblin army knife digs trenches, saws wood, hammer nails, light fires, sounds three different kinds of duck calls, polishes and oils armor, sews clothing, stores 25 feet of spidersilk rope with a test weight of 100 pounds, extends into a fishing rod, and unravels into a 1-person canvas tent. All this utility in just 4 pounds, and it even cuts things.
