The brine sabre is a one-handed weapon that requires an Attack level of 40 to wield. It is dropped by brine rats in the small cave accessed during Olaf's Quest. The brine sabre is a slightly better alternative to a rune scimitar, boasting 2 higher strength and slash attack bonuses when compared to the former. However, it is significantly more expensive due to the fact it is only dropped by the rarely-killed Brine rat at a rate of 1/512.
Brine sabres can finish off rockslugs without the use of a bag of salt. It is also one of the only weapons that can be used to kill lobstrosities.
It is required for a master clue scroll.
Training
The brine sabre is the best-in-slot training weapon for level 40 Attack pures who train on members servers. It was also previously the best-in-slot training weapon for granite maul pures who lacked 55 Slayer (in which the leaf-bladed sword was better as it provided +20 higher offensive and +3 Strength bonuses), however it has since been superseded with the release of the granite hammer, which provides +10 higher offensive and Strength bonuses.
