Now in terms of the chisels - that I'd like to talk about! Woodworking chisels are always tempting, but remember that we're trying not to make a smooth flat surface. We're trying to engrave. And the rule is to break, tear, pull and crush, but never cut. So the chisel you want is not sharp like a woodworking chisel - it's dull with a shallow bevel. Typical woodworking chisels are very sharp with a pronounced 25-30 degree bevel. For deadwood carving they should be more flat and dull like a flat head screwdriver tip. The blade should be short and the steel and handle should be good quality so you can put some force on it without worrying about it breaking.
Here's an inexpensive one that can work:

Downside of this one is that I'd like it to have a big round handle. After a couple of hours with the end of the stick jammed into the palm of your hand, it gets uncomfortable. This is the one in Francois Jeker's book. I think all of his are modified from other tools.
