Since I haven't read the manga, could you improve this (good) answer by adding a comparison of the veil of ironsand you show in your second image with another (or multiple other) scenes of her ironsand attacks to show that it's the same way that the manga artists draw the ironsand?

It's really much of the same in any media, a veil of black. You even see it cut off stuff in the Level Upper Arc http://i.imgur.com/STwgd3b.jpg

<p>In the Railgun anime's third season in episode 6 at 19:36, Baba orders a type-Mantis robot to seize Misaka, but as the mantis claw <sup><sub>(pretty sure real mantises don't have claws like that- but I digress)</sub></sup> closes in, the screen blinks white just for an instant (as if to say that moment is too cool or happens to fast for the viewer to see), and Misaka somehow severs the claw and some of the arm it is attached to, launching it into the sky. One sees as the claw arm flies up and when it lands that the separation point looks like a clean cut, and is red-hot. The screen then shows the mantis looking at what's left of the arm it tried to grab her with- also showing what looks like a red-hot, clean cut, where the red-hot quality extends what looks like at least one hand-breadth into the length of the arm where the separation happened.</p>

<p>To my memory, having watched the three seasons of the anime before, and now being in the process of watching them again, she is never shown doing something similar or creating a similar effect/outcome (red-hot, clean cut of metal), so as someone who hasn't read the light novels or their manga adaptation, I also wonder if this is something that only happens in the anime, or if it also happens in the light novels and their manga adaptation, and if so- whether there's any more information there or in any other moments that explains how she did this.

<p>I know she can make a sword out of ironsand (season 1 ep4 at 18:12), but there's no trace of her using ironsand in this scene, and I'm also a little doubtful that her ironsand sword would cause more than one hand-breadth of red heat to linger in the severed arm.

<p>As part of my research, I also tried to think of other scenarios in the anime where the opportunity was there to show her using a similar ability. In season one, there are two scenes against Therestina where Therestina has Misaka in the clutches of her robotic suit (ep23 at 16:04, and ep24 at 16:18), but in both those scenes, Misaka is mostly incapacitated by Capacity Down. In season two, there's the scene where she launches some steel beams at Accelerator and he reflects them back to her (ep6 at 3:54), but I don't see how such an ability to cut through metal would save her there, unless cutting the beams could divert the split sides away from impact with her body (which I find physically hard to imagine at the speeds they were travelling at), and there's a short kerfuffle with a powered suit (ep20 at 11:27), but in that fight scene, Misaka either dodged the suit's physical attacks with its blunt weapon, or blocked them using a moving stream of ironsand as a shield.</p>

How did Misaka sever this type-Mantis robot's arm? With her bare hands?

Is likely her signature iron sand.

In chapter 52 of the Railgun manga, which is anime is adapted from, for the most part, we see her gathering what looks to be iron sand (second panel).

[![Iron sand is charggging](https://i.sstatic.net/OcjR0m.jpg)](https://i.sstatic.net/OcjR0.jpg).

On the next page we see a stoke of black, reminiscent of a veil of black iron sand.

[![next pg](https://i.sstatic.net/VESK2m.jpg)](https://i.sstatic.net/VESK2.jpg)

The second attack is clearly a lighting spear strike and more of a severing attack than a slicing one.
