I have very mixed feelings on this issue. If the man did not present a threat, I would not give him my wallet. But, if he isn't armed, why does he have the testicular fortitude to attempt to mug me? .. unless of course, he is a 6'6" guy with huge hands who could strangle the crap out of me. Then, of course, he's a threat already.
How would I know he wasn't a threat? Guns are concealable, we all know.. knives even more so! If I were accosted like that, I would try my best to get him off of me and get him to back down, keeping an eye on his every move until I see a weapon of any kind.. then I would draw my weapon, anticipating him coming at me again. The situation would go from there. Either he backs down or I fire. Hopefully he backs down.
Assessing the situation and deciding whether to use deadly force is the hardest thing to do for me, as a CHL holder. I have had ZERO experience in it, but I play the "what if" game in my mind when I'm bored, preparing for the numerous situations that could occur. Things are never how you plan them out in your mind, but at least I'll be slightly better prepared.
One of my best friends was attacked last year in a local park right before Thanksgiving by three guys of similar age [between 17 and 22]. It was pitch black and he never saw them coming. Three guys against one is almost a sure situation to draw a weapon, especially after dark. However, he was unarmed. They stabbed him nine times in various places while he was fighting back, and then held a gun to his head. He stopped fighting when he heard the gun being cocked. They took his wallet and his shoes.. didn't really get anything else.

Fortunately and amazingly, he survived by eventually getting up and walking to a friend's house about 1000 feet away. He lost 3/4 of his blood and had no vitals upon arriving at the hospital, but he is alive.
My point: a simple mugging can turn deadly VERY fast, whether you see the weapon or not.. so if some teenager has the gall to approach you and demand that you give up something, don't assume it's a situation where you can knock him over the head and go about your way. They are rarely unarmed. If you are outnumbered by multiple thieves, that in itself would most likely present an imminent threat. They wouldn't try to mug someone who could obviously take them on. Stay alert.
Sorry for the long post.
