There is nothing so fast in roughing out a wax shape as the spiral
saw blade. Of course you sacrifice some wax due to the coarseness of
the cut, but wax is cheap. And, the edges you are left with are also
coarse. However, I never try to get a fine, and finally edge with a
saw. I always carve/ scrape my details. I have not tried a skip
tooth saw blade yet, but will do so in the future.
Ah, spring time to work the gardens.
