Problem: I ordered the set of swords on December 9th (Sunday) and recieved the swords today (Wednesday, the 12). The Shipping was absolutly BLAZING! UPS Shipped with a Tracking Number made me confident in Sword Demon. Packaging was great and everything was alright. I would deffiently buy from Sword Demon again.These swords are UNSHARPENED. It would appear that Stainless Steel is not very good for sharpening them either. These are really "Wallhanger" katana's, But when your buddies come over and see them, they almost cry. These are just the coolest swords because of the movie. All the symbols and words on the blades are actually etched. The symbols and the like are the exact same from the movie.
Solution: Positive
