It's definitely cool to see GEC doing rare old patterns. The Wharncliffe blade is something that I haven't seen on congress jacks and the I haven't seen an "office knife" congress jack but the "speaker" is a very traditional pattern. The old congress jacks are hard to find. It's not a pattern that I would typically use. To use, I'd prefer a single spring. I also prefer a shorter sheepfoot for better control when starting a cut in the middle of something. A single spring requires the sheepfoot to be shorter also takes up less space in a watch pocket. But as a fan of the oldies, I'm happy to see GEC making these knives. I don't recall anyone else making them either.
