Here's something I came across in a hearing-supplies catalog. (Don't
ask.) I think it could be the bees' knees for wax carvers. It's a
lighted ear curette - a tiny cutting tool with its own light source,
presumably for ear cleaning. It might be just the thing for small
inside curves, etc. The website - www.warnertechcare.com
registration, so I haven't really looked into it. They also post a
phone number: 800-328-4757
Since I don't do wax, I've not pursued it further myself.
