Bonsai Wire cutters have a rounded head to allow you to get into the tree and cut wire without damaging the tree. If you're planning to style bonsai, then you really do need to ensure that you can remove wire without accidentally removing the whole branch (very bad for design!)
Ryuga tools are made in China- originally for the Japanese Market. They are a high quality tool without the premium paid for Japanese tools. I use these tools myself and I'm very happy with them.
