DiamondCore Tools P4 Teardrop Zebrawood Pencil Carver From  £53.43

Much like the rest of this range of tools it allowed you to do your decoration in double quick time, very sharp and very accurate, even the feel of the tool in your hands makes it very easy to use. Highly recommended.

This is a beautiful tool that makes carving an absolute joy. It may seem expensive but it is extremely good quality and makes for a very clean line on pots - I absolutely love it!
