Jesus. I've caught her on YT several times and she seems like a decent chick rather than your typical parasocial/camwhore type, although fuck knows what the hell she was doing dicking around with a sharpened blade like that. Reflexes are a bitch, I'm kind of a slave to mine when it comes to lurching after something that got knocked over/is falling. Had to get stitches on my hand after trying to catch a glass I knocked over and instead landing on the broken bottom piece. Luckily I managed to shift my weight off it before it severed the tendon so I just needed the stitches and not surgery.
I actually did catch a falling knife by the blade once but I got very lucky and managed to pinch it by the flat. Worst part was that nobody saw me do it because it was pretty awesome.
