I always bring two--and NEVER leave camp without one on my ammo belt...the one I use a lot is a buck..with two blades..one is a saw blade..flip it over and can use a regular drop point blade..cheaper knife and easy to sharpen in the field..carry a little sharpner with me all the time as well...use it all the time whether in Africa, Alaska or Montana...

Also have a leatherman with me which is a multi-tool with a knife blade as well...usually keep that in my pack I take along in the field...never know when you might need to tighten something or have a need --feel its better to b safe than sorry...
