Edge bevelers are not exactly cheap here, but they are not ruinously expensive either. Tandy sells seven different sizes of edge bevelers at prices rangeing from $10.00 to $13.00 USD and Circle Slicker Wheels for $2.49 USD. Shipping to Norway might be prohibitive, and there might be tarrifs to deal with, but you might want to check with Tandy Leather at: http://www.tandyleather.com/ .

It might be a reasonable source for leatherworking tools.
