when working with any stone where dust is in the air stream it is a good idea to protect yourself. If you knap do it out doors, Do not do it inside ever. I knew a knapper who died a few years back and he was in his fifties his lungs where all scarred up from breathing flint dust for years. Silicosis is as bad as black lung and it dont go away. it is a slow killer, if you knap inside it will get you sooner or later and it aint a pretty way to go either.
That is just in case Roger and Greg have not scared you bad enough.
