Has anyone purchased anything from there? I bought a few things from there and even dropped a couple hundred on a katana. One day, I decided to test the katana's durability and tried to cut through a 2" thick tree branch, a single vertical slash, and while it cut into it, the blade was slightly bent out of shape. The blade is razor sharp to the point where if you even just tap the sharp side, you'll cut your finger. So is that the fault of the katana's quality? A fault of mine? Have you purchased anything from this site and experienced poor quality?
