Ayvah, please pay attention. We were talking about appearance. Must I quote my original argument again?
You're saying you're talking about appearance, but you contradict this by trying to demonstrate that these words cannot be used to describe appearance.
The function of sharp claws, the function of sharp teeth, the function of breathing fire on your enemies is violence.
The effect of seeing tools that appear designed for violence is that they appear violent. Seeing a soldier armed with an AK-47 looks violent. Many songs censor the word "gun" for their radio version due to this truism. Of course, everything is subjective, but this concept should not be controversial.
If you're determined to continue splitting hairs and need me to look at a dictionary then I can refer you to
Dictionary.com, where the meaning includes "
characterised by an uncontrolled, strong, rough force"
