I like the Milwaukee knives, I have two FastBack 2s and the black one whatever that's called. But I have to say I carry the Gerber EAB Lite now instead of a "pocket knife" per suggestions here on GJ, and I use it for EVERYTHING. It's like having a pocket knife and utility knife always handy in compact form. I just cut a bunch of vinyl plank flooring with it even and replaced the blade after. My other knives stay in the toolbox now.
I use it everyday for something. I had to cut up sandpaper yesterday, figured it'd kill the blade so I'd never do it on a regular knife. Nope - blade is fine. Split a bunch of 14/3 NMB and cut vapor barrier, opened several packages, etc today. I love it!
