Yes—startling, but not catastrophic. I first used something like that at age 6. It probably COULD cut flesh if you really tried, but it would take some determination, and just the specter of damage was enough to keep me on good behavior.

I remember it as helping me develop a healthy respect for tools, and also to relate to the material world as something I can manipulate rather than something to be passively consumed. And to manage risks, and confront my fears.
