But that was also a kitchen knife or an otherwise small blade. Slitting someone's throat with a kitchen knife is fairly straightforward, but a beheading? That would take a much more significant blade. Unless we've truly missed something quite major, there aren't many things that could be used, and I would say that most of them would be our personal weapons. An sword, an axe, a spear— Things of that nature.

As for the rest, if it was you, I certainly don't think it was your intention to use your own weapon, but it was necessary. To me, the nature of Gilbert's death implies that it was much more hurried, whereas Alisha's was planned. If it were anyone else, they would have had to bring a weapon with them if something unexpected happened and things went wrong. You don't.
