Hi Justin,
G'day and
.
There are a few Kiwis and a few more Aussies who have made themselves known on the forum.
Are you based in the North or South Island?
Many before me will have suggested that the best tools are available from this forum - if you can't spring for the airgraver yet (the exchange rate isn't helping much) I would consider starting with some of the hand gravers (or pehaps the hammer and chisel) and blanks rather than the traditional tools which won't fit into Steve's sharpening templates.
Let's hope you can find someone local to help you along the way.
Roger
