1. I recently started and finished brotherhood, it's actually what started my staying up all night spree of the past week or so (like I went to bed at 5am yesterday) and I can thoroughly enjoy that tat, but I wouldn't say he enjoys killing state alchemists unless he had the tattoos of Scar's brother's arm.
On another note, I bought one of those fry slicers, that will slice up a whole potato, and short of the brute force needed to slam the potato through the blade, it's pretty nice.
I can't see an old woman using the thing rather effectively unless she has some good arm strength on her.
