I like a guard. I have a nice scar on my hand from cutting out roots with a machete. My hand slipped and went the length of the blade. I was lucky and have nearly full use of my hand. It nearly severed my thumb at the palm of my hand. I have since been extremely careful how I use any sizable knife without a guard. If I have a choice I will use a guard and a thong to keep my flesh away from a sharp blade. The same injury would likely cost me my career now.
