This weapon is essentially a chainsaw compacted into knife form so that it can be wielded with just one hand. Nevertheless, the Ripper inherits many of the qualities of its larger version. The attack button can be held down and it will dismember anything in front of the Courier and its continuous cutting action means the ripper ignores Damage Resistance and Damage Threshold. This makes it very good for handling multiple enemies or large, but slow, creatures.
When damaging some enemies, like mantises, green blood will be sprayed instead of red.
The Ripper does not have a visible trigger or button to activate it.
The damage and DPS displayed is counted for 1 second of continuous attacking. The critical damage, however, is counted for every damage tick. Those ticks happen tens of times per second and because of this, the Ripper, along with other "hold down for continuous attack" melee weapons, is extremely strong with critical chance/damage bonuses. With no critical damage bonuses, difference between 0% and 20% critical chance is double the amount of damage displayed. With 100% crit chance the damage seems to be seven times the basic amount.
This weapon, like all other continuous attack (automatic) close combat weapons, has only its "start-up attack" animation sped up by attack speed bonuses, while damage dealing and DPS is completely unaffected.
Sometimes, a Ripper (Arcade Gannon's special version) is in one's inventory that is available for use and does not show up in the shop menus, but if it is dropped, the PC will not be able to pick it up again. [verified]
Due to an engine bug, the Ignore DT/DR effect does not apply correctly and because of this, Piercing Strike gives a marked improvement in DPS. [verified]
