Hi Macca,
Some nice pieces.
I personally use mine straight up in the English manner as it was how I was taught and what I am used to. I think the angled style to be more continental in origin and use.
If it is a veg. tan you need to burnish it prior to all the "stuff" being put on it. Some veg. tan takes a burnish better than others. Lightly dampen, wait a small interval (varies) and the buff with canvas, etc.
I am in the minority. Mine is about 3/16" square roughly. The reason for this is I also use it for a barrel mark for my guns as well. I plan to make one just less than 1/2" or leather only as soon as I can find time.

Its been a long time since I used the full version instead of the mobile for this website and I got confused.
