Rubicam: MY former wife used a wood burning tool on goards and that is bad enough. It takes a delicate touch, but you don't get past the smell.
As to whether it was done, historically, I am sure that sometime, around some camp fire, a cowboy took a hot coal, or nail, and used it to burn his name or initials into his horn. Branding irons were used not only on steers, and cows, but also on logs in the logging camps, to identify the source of the log at the mills downstream.
