Welcome to the Lies of P how to repair weapons guide. The game doesn’t teach you how to fix weapons when the durability drops early on. This guide should help out.
Refer to the Lies of P Achievements & Trophies Guide for details on all achievement/trophies in the game.
How to Repair Weapons
When your weapon durability drops too low, your attacks will slow down and do less damage. To remedy this, keep an eye on the durability bar in the bottom right corner.

When the durability is low, preferably before it turns red, press D-Pad Down to switch to the lower belt. Then, press and hold X/Square to use the grinder to sharpen and repair your weapon.
That’s it for the Lies of P how to repair weapons guide. Please post any questions or comments below. Thanks.
