It's called a "scorp", but is really just a specialized type of gouge.ginshun said:Sorry for never answered this question. The only tool I used on those two pieces was the "Carvin' Jack". It is a 6 bladed carving tool made by Flex-Cut. All six blades lock, and it works really good. The indent was caved with one of the tools on it. Its kind of like a 90 degree scoop, but I am not sure what it is actually called.
