Ozy,
I have a clasp knife just like yours, only thing is, it's about 50 years old!
It's more of a collector grade than real EDC use; It was packed with cosmoline for about a quarter of century, and it's very stiff to open. No rust whatsoever, though. Made by ABL, 1951.
Weird, because it is usually designated as 'British Army Clasp Knife' but it has a marlinspike...
