These are the crude blades crafted by former Caesar's legionaries after they became marked men. Like distant mirrors of their new and unknown Legate and a symbol they can hold on to, while The Divide tears at them.
A smaller variant of the bumper sword, although stronger, it is slightly weaker than the Blade of the East held by Legate Lanius. It is cleaner in appearance than the bumper sword and Blade of the East, with a polished blade and without rope connecting the bumper and pipe.
It has a special 'Mauler' attack, which does 50% damage and has a chance to knock enemies down or disarm them. This can be selected in V.A.T.S. at the cost of 38 action points (requires a Meleeskill of 50), or activated by running and holding down the attack button.
