When it comes time to add dagger work, you'll need another about 15-18 inches long. Too expensive for a master to have a dozen of them just lying around for students to practice with. It's a substantial capital outlay. Naturally, you'll want to have your own, and when you're ready, I'll be glad to help you find something good. No point in buying a piece of junk though, so start saving up now.
Steel really hurts.
Wood is safer to work with during that seemingly endless period during which you attempt to learn how to distinguish a hawk from a handsaw. If you like, you can wear gloves while practicing. I usually don't. I like the feel of the steel and it builds up a little tough skin in all the right places to practice bare-handed. At that stage you'll have to invest in more protective gear.
