Craig--
Well, if 'twere me, I'd ask the Scottish innkeeper:  "Is there a shop that sells knives nearby?  I'm a collector, you see..."  Admittedly, that requires you to be at your destination before you can get an answer...
On a more serious note, I don't know.  Case's dealer locator is only for the USA, though their web site mentions a German line of products.
Seems this is the reverse of Scott (Casual Hero)'s question in the thread:  Mickey Mouse Survival Supplies.  Perhaps one of the members from the British Isles can provide a better answer.
The search would be part of the adventure for me; YMMV.
