Rhino

Rhino (animal)

A rhinoceros is an African animal with a dangerous horn, a thick hide, a nasty charge, but luckily very bad eyesight.

Rhinoceros horn was used by ancient cultures (e.g. the Myceneans) as a form of ivory, but is inferior in quality to elephant ivory due to its yellower hue, and less even texture, leading to more flaws during carving.

Rhino (SCAism)

"Rhino" is a derogatory term in the SCA for a fighter who fails to acknowledge legitimate blows -- presumably because he has the thick hide of a rhinoceros so the hit is called "light".

Also: Rhino-hide.
