Leigh Teabing's walking sticks?

[TheFisherKing]

I was watching "The Da Vinci Code" a few nights ago and was impressed by Sir Leigh's (Ian McKellen's) walking sticks/crutches:



Does anyone have any idea where I could get a set of walking sticks like these? Would it be easier to have someone custom make them? They don't really look like the type of stick that would be mass produced. Any thoughts are welcome!

Thanks,
