DH is a keen cyclist & just uses his same face razor for any other unwanted hair. Don't see why it wouldn't work. It's the same sort of electric or battery operated type that just has tiny rotating heads, hard to hurt oneself.
I'm sure I was shaving with real razors at age 11 or so, no problems.
I've shaved my DDs pits for her. She wasn't impressed with the stubbly regrowth even thought it was unoticible to anyone apart from her. She has tried plucking it <eek>, she now uses Veet under my supervision.
Dd 11 (12 within two weeks) has had leg hair for sometime when it became a problem she started epilating, not bother by the pain. Dd is now starting to sprout long dark under arm hair not bother yet but has become aware of it. Her hobby is swimming so it with also be noticed by others.
What the best route to go? Was thinking waxing, but not sure and would like to be prepared in advance of dd want to get rid of it.
