Andy will ship overseas for a small additional cost if you buy a knife directly from him. They are available in his "Fiddleback Friday's" in his subforum on a certain blade related forum, posted every friday.
I don't believe anyone outside of the States sells them.
There are also some available from an online vendor whom I have had many great dealings with. A google search for "KSF Fiddleback" will steer you in the right direction. I've probably bought 15-20 knives from them, had them shipped across the border to Canada, and not a single issue yet.
He certainly has a talent for handle ergonomics. I've got two Bushfingers, (an S35VN stainless, and a 1/8" O1), a 12" machete, and a Bushcraft Karda. All are fantastic.
