Pirates were essentially opportunists and many of the necessities of pirate life like food, medicine and weapons were taken from their victims. This meant that the weapons used by pirates were no different from those in common use among the seafarers of the times:
The cutlass is believed to have evolved from the long knives used by the original buccaneers to butcher their meat for their barbeques. Its short broad blade made it ideal for use in the confined space of a ship and it was the favoured weapon of nearly all fighting men at sea.
With its shortened barrel the musketoon had limited accuracy but, like the cutlass, was easier to use on board a ship where enemies were close and accuracy was not essential. The brass-barrelled musketoon pictured below dates from 1758.
The pistol was light and portable and so was the ideal weapon for boarding the victim ship. One major problem (especially at sea) was that if the gunpowder got damp the gun would misfire. The pistol could only fire one shot at a time and as reloading was a lengthy process the pirate would have to carry several pistols or use the butt of the gun as a club.

Easily concealed the dagger was ideal for a surprise attack and was useful in areas where there was no room to swing a sword. This picture shows an Eighteenth century naval dirk and its scabbard.
The boarding axe was used by pirates to help climb the high wooden sides of a ship and once on the deck could be used to bring down the sails. This is a naval boarding axe of 1870.
This was used to store the gunpowder needed for the pirates various pistols and muskets. The picture shows an Eighteenth century powder horn.
