Olive wood is lovely to turn, can be a touch oily so be careful with the finishing technique ca can bite back after a while.
Keep hold of it for a few months to get some *confidence* in it before departing with it.
It can also be a lot more figured but a lovely pen none the less.
Phill, i like to use BLO on Olive wood, then leave it for a few hours or even better over night, then give it a friction polish and a wax finish, the wood comes up very clear and with a good shine ...
The more wood you take off the less grain ... Also just a quick tip, try to round off the ends near the center band, it gives the pen a better feel ...
