So it is called a "Timber Scribe", I feel better now that you posted this new info.and pictures of it. I think yours is a fine looking example of one, and having one that does not shine, is better than having none at all, like me! I would love to have one, and now that I know what it is, I WILL find one, eventually, and buy it.
It appears to have an oak handle, is that correct? How do you plan on cleaning it, ie. wire brush, vinegar, evaporust, etc.? It looks to me that a fine grit sand paper may be needed to remove the pits, so don't be afraid to go there if needed. I sanded a pitted knife blade with my 1x30" belt sander/sharpener about a month ago, and it worked great.
Nice Find,
Wayne
