Neither option induces vomiting.
Elk is easily my top choice. Elk is not sambar stag, and rarely competes with it in a beauty contest, but for me it has a lot to do with what it is and what it represents, and not just what it looks like. But I find it very far from being unattractive (unless super chunky).
It's a strong, majestic, American animal that didn't have to die to make us a knife.
PS
I have lots of knives made from dead animals. It is a factor though that I do consider greatly when choosing my knives.
