Melee

Melee Combat has been fairly limited within the Tomb Raider series, though there have been some weapons to allow close quarters combat.

Climbing Axe
Lara's climbing axe doubles as a melee weapon. It is based on a DMM Rebel Ice Axe.

It can be used for swift strikes, executions and stealth finishers.

Tactical Knife
Lara acquires a knife for stealth takedowns and finishing movies in Rise of the Tomb Raider. It appears to be Soviet Era. It can also be used to cut ropes.
