User blog comment:Gundam Legilis/Volume 1 Weapons In Depth- StormFlower/@comment-10390252-20140620104640

Regarding Storm Flowers' blades, I think that it's best to view them as hand-held small single-bladed axes. In esence, they are sharp knuckle-dusters but also knives running along the outside of Ren's fist. They can be used to block, cut and, as we saw fighting the King Taijitu, daggers. I have no doubt that Ren has a specific jitsu tailored to use those weapons optimally in hand-to-hand combat.

It's curious how low-powered the gun mode seemed. Either this is a trade-off (more powerful propellent payloads would make them harder to handle) or there is some other factor that we aren't aware of. Maybe Ren had loaded them with lower-power hollow-tip ammo, not anticipating going up against biological tanks like the three giant Grimm he faced during the Initiation Test.

The thing to remember about reptiles is that they have very distributed nervous systems and are very resistant to injury. Unless you take out the brain or heart, they tend to keep coming at you. So, a projectile weapon (which would cause small point damage) would be ineffective against a foe of the size and nature of a King Taijitu - an ATGW would have been better suited against them. Similarly, that type of weapon isn't well-suited for a living tank like a Giant Death Stalker.

That said, I'm not convinced that it would be ineffective against an Ursa or Beowolf. or smaller versions of the other Creatures, espeically if he hit the head or heart. We'll have to wait and see.
