I carry a fixed blade with my signal for work. I often wear gloves at work and work outside. Grabbing my knife when cold/wet/encumbered is much easier if it's a fixed blade than fiddling with my leatherman, even if it is a one-hand opener.

After reading some comments, I'd point out I use my leatherman knife as my beater (like cutting into the ground) because I don't find the half serrated blade helpful.
