Swordfish gloves are a reward that can be purchased with 200 tokens from the Fist of Guthixminigame and cannot be bought from the Grand Exchange. They require a Fishing level of 65 to wear (this can not be achieved by using boosts, e.g. Admiral pie). When worn, the gloves grant an additional 100 Fishingexperience for every swordfish caught. This extra experience boost lasts until 1,000 Swordfish have been caught, after which they crumble to dust. To check how many charges players have left, right click in the equipment screen and select "inspect". Players can only buy one pair of gloves until that one had been destroyed. Trying to buy two pairs at once will result in buying only one, and receiving a notification.
Contrary to popular belief, Swordfish gloves DO NOT make you catch swordfish exclusively. They have the same catch ratio depending on your Fishing level.
400 (100 exp. extra per raw swordfish x 2 SC Harpoon)
The experience gained from this item is doubled from using a volatile clay harpoon (or Sacred clay harpoon) from the Stealing Creation activity. With both swordfish gloves, and a volatile or sacred harpoon equipped, a player receives 400xp per swordfish caught with the Morphic Tool, and 410exp with the Volatile tool. It is recommended to use Morphic as the Volatile does not significantly increase the exp rate.
