I go back and forth on partial serrations.

They are a pain to sharpen, but in my experience stay sharp a very long time. And they will also still cut even if slightly dulled.

For things like rope and similar, dull serrations will beat a dull main blade.

As to all the folks who say you should just keep your main blade sharp, if you are ever in an emergency situation and do not have capability to sharpen, things can change.

I carry my gripptilian everyday, but do not carry sharpening tools. I do keep them in my emergency backpack in my vehicle though.
