[Bonetools] Brushes

[Ariel Shatil]

Hi Marit, thank you for the information!
Indeed I noticed the tunnel crossing into each line of holes and thought it
was serving a similar purpose as the incisions, and probably related to
attaching the tufts.

Here's a little story about how the modern tooth brush was invented, and
guess what: it was a bone tool from the inventor's dinner. The story is
from Wikipedia, so I'm not sure whats fact and whats legend.

"In 1770, he (William Addis) had been jailed for causing a riot; while in
prison he decided that the method used to clean teeth – at the time rubbing
a rag <http://en.wikipedia.org/wiki/Textile> with
soot<http://en.wikipedia.org/wiki/Soot>and
salt <http://en.wikipedia.org/wiki/Salt> on the teeth – was ineffective and
could be improved. To that end, he saved a small animal
bone<http://en.wikipedia.org/wiki/Bone>left over from the meal he had
eaten the previous night, into which he
drilled small holes. He then obtained some bristles from one of his guards,
which he tied in tufts that he then passed through the holes in the bone,
and which he finally sealed with glue. After his release, he started a
business that would manufacture the toothbrushes he had built, and he soon
became very rich. He died in 1808"
