These are examples of the work I do as a sword maker from Castille Armory. It's very production minded historical inspired rapiers and other examples which are designed to be used in sport combat. The company does produce sharp swords. However we are not using the proper materials for the high quality blades I've seen on this forum. All the blades are formed by stock removal from pre-tempered blanks of 5160 at about .21 inches thick. Hardness is about 48 on the rockwell scale, all the way through. If you have any other questions feel free to ask! I made the majority of these blades from start to finish. Since i am in a business, the other employee with me has had his hand on some.
