They are made from Iroko! I've never tried to source illegally logged west african mahogany to make my boards
I'm guessing it'd be quite difficult and a rather unsustainable business model. Much easier to go to the timber yard.
Iroko occasionally referred to as Iroko Mahogany due to its similarity in finish and properties to Mahogany is a very commonly used hardwood timber, an example being hardwood timber framed conservatories, virtually all are made from it. High quality, stable, good looking...!?
Toby it does feel slightly different to the Ash, a little smoother finish, only noticeable on the slopes really.
