Had one of those "can field dress 3 elk and 4 grizzly before resharpening" knives.

Went dull as a butterknife 5 minutes into field dressing an elk. Of course, there was no pocket sharpener available either.

Bought a WorkSharp when I got home and went over EVERY knife I own. I also ALWAYS carry a sharpener, and when hunting elk, an extra knife!
