Hi All - I'm looking for info on the Case XX P210 knife. I've seen multiple versions of the knife and I'm wondering if anyone knows the history of it. The shape seems to be the same but the markings are different. Some just say "CASE XX P210" while others have "***" before and after the branding. The sleeves they come in also seem to change. Which is older/newer? I'm also interested in buying these if anyone has one (or more) for sale!
