"A regular household kitchen knife."
Butcher Knife (ブッチャーナイフ butchā naifu ) is a melee weapon that appears in Resident Evil Outbreak.
It is a weak weapon by doing 60HP to enemies, but is more powerful than the Folding Knife. An experienced player can use David's knife combo to make it much more effective against enemies, especially zombies. While still difficult, it will improve his ability to hit aerial foes. The butcher knife will do five times more of its usual amount of damage to certain bosses, specially the Suspended.
It can be found in both Resident Evil Outbreak and Outbreak File #2.
