Be careful if you're looking for "battle-ready" swords, as most of the swords in the market (especially the low cost swords) are anything but. Anything made of stainless or hardened should be avoided, because even though these are great for knives, they're lousy for swords. If you're just looking for display weapons, however, there are a number of companies that make beautiful swords (United Cutlery, CAS/Iberia, The Noble Collection).
