Dear Peter
Unfortunately in GREECE wy believe the olive tree can be used for 3 things
1. oil
2. olives
3. firewood
They surprised with the constructions(bowl-pen-sculptures etc.) but they like that
My main job is furniture makers and woodturning i started before 1,5 year
In that time I have sell enough of pens and few bowls but until now is for supplement my working time and with the crisis here wy have plenty of time 
Regards
Giorgos
