Cybernetic Arm and 'Touch' attacks

[Blaise Carey]

Hey y'all. I've heard a lot of good things about this game, and finally have the time to come next April. Right now I'm just going through the book and I have a question or two on melee attacks and how they interact with the cybernetic arm. 

How are 'brawl' attacks handled? Is there an applicable skill, or do you just need a 'fist' weapon?
Can the knockback from Cybernetic Arm 1 be applied using a touch? That is, if I'm a gunner and a melee enemy closes on me, can I use the arm to apply the knockback to gain some breathing room, even if I don't have a melee skill?

There is no brawl skill or way to make brawl attacks in Spite. Use of the cybernetic arm 1 ability requires a melee or thrown weapon skill.

Fantastic! I figured as much, but wanted to clarify.
