Weapon Cord

Source Advanced Player’s Guide

Weapon cords are 2-foot-long leather straps that attach your weapon to your wrist. If you drop your weapon or are disarmed, you can recover it as a swift action, and it never moves any further away from you than an adjacent square. However, you cannot switch to a different weapon without first untying the cord (a full-round action) or cutting it (a move action or an attack, hardness 0, 0 hp). Unlike a locked gauntlet, you can still use a hand with a weapon cord, though a dangling weapon may interfere with finer actions.
