Yep, I have mine bound to both mouse wheel up and down. I flick that wheel anytime anyone gets near me.
I bound it to mouse 2 so it won't hinder my aiming with mag-scatter. Quick knife is very useful but also necessary with the slow firing mag-scatter, about 40% of my latest kills seem to have gone to quick knife and I auraxiumed two knives without much thinking about it this way
