With the current exchange rate, and the number of US knife makers available, I would say you would have to be a little nuts to buy a Woodlore clone from the UK right now. There must be hundreds of US makers with the skills to make such a knife. If you buy from the UK you have to pay for the higher cost of materials, fuel, tools, you name it, that the UK makers have to contend with.
The knife is certainly nice and will do what you want from a Woodlore style knife, but I would think that you could get something of similar quality made by a US maker rather more cheaply. All you need is an accurate drawing of the original and I am sure there are enough pictues floating around that you could come up with one of those even without help.
The import duty that we get hit with when ordering from the US means that there wouldn't be much in it for buyers here to go to the US, but for the exchange rate being so much in our favor right now.
