[Raven imitates Darin and twirls his own weapon, then holds it up as if to suddenly block an imaginary attack.]

Hmm... Not sure I like it. [He straightens, and lowers the weapon.] With a blade ya can use the flat to parry, but with this thing ya gotta use the edges. Either that or risk losin' a finger or two.

[Maybe it's just not meant to block attacks at all? But even a combat veteran like Raven isn't that fast or skilled to never need to parry. Maybe he's just not suited for something more specialist like this.]
