japan link to Huzzle
I asked on my Facebook page why Hanayama had called them a Huzzle and got a very interesting response from my Friend Taroh who is a native Japanese speaker:
???: (pronounced "huh-zu-su") means 'to take apart' in Japanese,
and puzzle is written ???: (pronounced "puh-zu-ru")
Hanayama combined the two words together to make up a portmanteau that describes a puzzle you take apart.
I started with the easiest of them - the Cast Diamond which was a design by Scott Elliot who specialises in designing rather beautiful shapes that interlock in unusual ways.
