I know that it's not "hand made" and not made in the UK, but if you want a UK style, UK designed, bushcraft knife, in the US, you could do a lot worse than checking out the Spyderco Bushcraft Knife.
If you check the right side of the blade you will notice a familiar logo
You could also check out the Bushcraft North West's offering which I spotted the other day.
If you were in the UK, then it would make sense to look to the makers already listed, but since you are in the US, and the exchange rate works against you, the above are valid options.
