The Fresh Blood-Dismantling Opener (のオープナー Senketsu Kaitai no Ōpunā?) is the killing good used by Emily Redhands. The form it takes is a single broken knife, however, the author can change the single knife into up to 46 different knives.
- Super Slice
- Blood Clot Prevention- Any wound caused by one of knives cutting the skin becomes unable to clot. This means any wound that the killing good creates can never naturally heal.
- Momento Attribute Adoption- Any knives created from the original killing good adopt the other two abilities.
