I use to order from BudK years ago. There is only one downside to ordering from them....wait for wait for it...There merchandise is cheap, chinese made junk. Nothing from there holds an edge very well, sharpens very well, or is made of good quality metal.
Look at manufactures like K Bar, and Sig. They make high quality pieces. K Bar also owns Becker knives now, who makes great survival knives.
Swords that cheap are only replicas. They will maybe get one solid blow in before breaking. Try Zombie Tools. Their stuff is expensive, but it's real. They won't break on you. Unlike the swords from your link, well.. take a look at this.
