When there used to be multiple large, well attended NKCA Knife Shows, you might see a knife like the OP knife every once in a while, but they were always just about used up. The long pen blade was especially prone to being way down.
Joe Seale wrote an article for KnifeWorld Magazine years ago about one such knife that was in fantastic condition. It had a leather thong through the hole. I have no idea what happened to that knife.
The Terrier I posted came out of Mr. Seale's collection after he passed away. Tony Foster bought it and sold it to the man from whom I obtained it.
It is the only such knife I have ever seen, Terrier or Robeson.
