Many say the rapier is usful as far as speed and agility, but many say as well it lacks the power it needs to deliver a critical blow or thrust. What is the power of the of a rapier's thrust? Can it go through a man if stabed and reach to the otherside of the man's back (can it go through a person and come out through the back to the point were you can see the blade on the otherside?)? Is the thurst strong enough to peirce armour? And what about the Sword Rapier with a sharpened balde, can it severe limbs and reach the power of a katana?
