A couple of things annoy me with most of the spades you buy new now is that either the head is to big, or the angle that the head isnt steep enough making it awkward when trenching back the hole.
I used a spade of a friend of mine made by bulldog on the weekend he said he bought as it was, the head was perfec size and it had a flat bottom to it which nade it ideal for drawing foxs if you broke in on the brush, he said they were advertised to terrier and ferret men but dont know if they still make them or no.
