Most and least important weapons

[Glib]

What do you think qualifies as the most important weapon in the game, and the least important?

*Note I said "important" not "effective": The idea being that weapon may be very effective (damaging), but perhaps another weapon fills the bill just as well, or maybe there just aren't that many scenarios where it's needed

My votes are:

Most: Cutlass ( I use it everywhere and it delivers)
Least: Pistol (It can be pretty devastating but I use the dagger for ranged attacks more often)

... oh and maybe tied for Most Important with the Cutlass would be the Ship's Broadside
