Swords from the same mod that adds the dogs, though you need Anomaly (it's meant to be some sort of crusader gear and has a bonus against entities). Other weapons in that same "set" is a sawn-off double barrel (references Terry Pratchet in the description [and Doom]), an autocannon, and a classic looking rifle.
