I have a few SAK's that have a partial serration and they are ok as a pocket knife. The blades cut meat really well and other things, like paracord. I much rather have no serrations though.

For a fixed blade, I do not own, nor will I own a blade with serrations. Not for an outdoors knife in my opinion. I don't need to cut any ropes. Serrations are ok on some kitchen knives, as long as they stay in the kitchen.
