I think if you are going to be around people you have to worry about perception. For that the hawk is going to be a better bet because it is seen as a tool.
I'd also bet for someone that is not trained in bladed combat such as myself the hawk would be easier to wield in self-defense and easier to defend those actions in court. Unless they find out it is a kill devil <img src="/ubbthreads/images/graemlins/doh.gif" alt="" />
Saying that just made me said about society. Good think the yard is around to remind me that intelligent people are still out there <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
