Cold Steel Naval Dirk: Origin of Design?

[Dmitry]

This what the dirk on the first photo is based upon, a popular form from the mid-1790s to ca.1810.
Sometimes there is 'cigar band' around the waist of the grip, which is engraved with a fouled anchor, which, understandably, adds a factor of desirability to collectors.
Both pieces are in my collection.
