Practice Shinai Padded Blue Bokken

I bought these to play with my nieces and nephews and for personal training purposes. I bought four of them for $5.00 each. They were cheap so I wasn't expecting them to be amazingly built but they are pretty sturdy. A real big concern I had when I unboxed them was the wooden handles. All four of my swords had really big cracks; that can seriously hurt someone's hand. It's like the manufacturer hammered a nail into the handle and didn't even care about the obvious cracks. I put some putty into the cracks and now they're safe to handle.
