Okay, the situation is this: a modern day everyday average guy gets pulled into a high fantasy setting. His first contact with the natives doesn't go well and he is instantly set upon by a native wielding a short sword. The native isn't a skilled warrior, but has some basic training in how to use it. He's in pretty decent physical condition, and in his mid 20s. His race is more or less comparable to a human's, perhaps a little physically frail in comparison. He has a buddy some distance away armed with a crossbow(similarly trained), although hesitant to make a shot out of fear of hitting his friend.
The 'modern joe' is in his early 30s, and while he has some hunting and target shooting experience with guns, the most he's ever been involved in a fight is a couple of barroom brawls years ago. His 'training' is limited to watching a few kung-fu movies, but he's in better than average shape(active and lifts weights regularly). He's armed with a large (1/2" drive, 18" in length, about 8lb in weight) torque wrench that made it through with him.
Would the guy have a chance of making it through relatively unscathed? I've tried searching for 'self-defense against sword' but have only come up with articles regarding swordfighting techniques and some martial arts discussions on the topic, neither of which helps in this situation.
