Pfft. Cutting veggies with a kitchen knife is dangerous. So are most sports. Lots of things in life are dangerous. But I note that I have yet to read of anyone here seriously hurting them selves. I personally have gotten *way* worse cuts from disposable razors than from a straight.

But, oh well. It's your parent's call at the end of the day.

As others have mentioned, at the very least, you can start adopting proper shave prep. Start trying out shave brushes and soaps/creams, instead of that foam-in-a-can stuff.

I know that for me, the shaving foam in a can *significantly* contributes to my skin irritation. It's got a lot of chemicals in it that aren't so nice on some people's skin.

Also making sure your beard is conditioned, and your skin is moist and hydrated before you begin makes a world of difference.

As far as razors... how about seeing if they'll go for a compromise?

Maybe they'd let you get a safety razor, or "DE." Because it doesn't pull the skin the way modern cartridge razors do, that might also be more comfortable for you, and since the blade is held in the head of the razor, rather than being completely un-encased, it is "safer" (or at least, if you cut yourself, it's not going to be as deep).

Maybe they'd go for that. Give it a shot.
