Well, it is very ypothetical question. If I have enough time I will go for my favorite shashqua. The problem is the scabbard. The invader will die with style.

If I have to be fast, I have a good kilij without scabbard in the right place. If the blow dont kill him the rust on the blade will finish him slowly.
But it is also question of the mood. How about an invader kebab with my flyssa?

I wouldnt try sort blades, he is maybe more skilful than me in martial arts.
