Repotter

Jin is the carving and bleaching of a deadwood branch.

The knot you show in your pic is on the trunk. To carve over that to diminish its appearance is to do a Shari. Which is to carve or make the trunk appear bare where a branch had been.
So yes this can be accomplished by carving the knot and stripping some bark from the trunk. I use a Dremel with a burring tool in it to remove wood and texture it. usually finish it off with a wire brush in the Dremel to give it a worn and weathered look.

Good luck wth it, Hec
