I carry my SAK every day of my life and simply move it into the pocket of whatever pants I am wearing, including hiking pants. My choice of SAK is conditioned on all-around use at home, car camping and hiking, so it is not as minimalist as Pika's kit. I carry the 'Recruit' model: big blade, small blade, can opener, bottle opener, tweezers, toothpick -- 1.65 oz. I use the toothpick fairly often. The other components all get used, too, but not all of them while I'm hiking.

I carry a separate nail scissors in my FAK. I find the spring-loaded tiny scissors on various SAKs and multi-tools don't work as well for me as a stand-alone scissors. They weigh another 1 oz.
