Harpoon

The harpoon is a tool used in fishing to catch certain types of fish. All types of harpoons(except the standard harpoon) can be wielded. The level requiredments for wielding each harpoon differ.

A harpoon is a melee weapon, available in all varieties of metals, although its power and speed are less favourable than many other weapons. All hatchets except for the Dragon harpoon and Celestial harpoon can be smithed using the Smithing skill. Both these items can indtead be found from various monsters throughout runescape, however the Celestial harpoon can only be found in the Celestial dungeon.

each type of metal harpoon gives the player an additional chance of receiving fish, also the giher tier harpoons have special hidden bonuses.

Hatchet List
The level required to wield a harpoon is different than the level required to use a harpoon to chop trees. Wielding is governed by Attack level while fishing is governed by Fishing level. For example, a player with level 1 Attack and level 61 Woodcutting can use a dragon harpoon to fish, but not wield it as their Attack level is not high enough.
