Hey, fellow Vet!
I am quite a ways from doing any carving, but it looks to be a formidable task. I had not seen pics like this that display the "carving". Pretty low stuff, almost like imagining it's there.
It does very much look like it was stabbed in, then nothing else was done to it. And with the finish on it, it does not look as tho it wore down from use.
Quite the conundrum - to carve or not to carve.....
