Welcome to you all.
Hardlined... I can address the rusticated v. sandblast vagaries.
There is a definite difference between the two.
One, the rusticated, is produced by the use of hand tools. Mostly seemingly lately the Dremmel tool.
The other, the sandblast, is as the name implies produced by sandblasting the bowl.
To tell the difference is sometimes not so easy.
But, basically the sandblast will reveal the grain in the briar, where the rusticated will not.
Edit: Hardlined... Serendipity...
This thread starts with a Sandblast and then a Rusticated...
