Integrity is known for releasing weird items and weird music. And often, their music is aggressive. To that end, they have released a weird, aggressive merch item. In conjunction with Wolf Brigade Gym, the band has released an actual, for-real-deal, battle mace. They're making 18 maces total in the following types: 8kg, two 10kg, and two 12kg maces.

The maces and ones like them, which are similar to the kinds that knights and barbarians would smash each other with, are used in conjunction with a sort of aerobic, strength training as practiced by Wolf Brigade Gym. The weapons are out now. See a video of a mace workout here.
