HSV RPG team 4 riddle 1

Team 4's mission, for the first Fei riddle:
"Long and deadly and created to kill."

We were all confused as to how simple the answer would be, but when the answer "Naginata" (a long samurai weapon) was suggested, we agreed that it HAD to be the answer... it has Bay written all over it! Naginata.... Sounds the same as NagiNada, which, of course is one of the most popular ships to board in this village xD (even though technically it should be Nadanagi... with the male first)
