Seawah,
Are you sure its not a 4 bladed camp knife? If so it sounds like the model #1760, of which we make thousands of a year, mainly for government contract. We stamp the blade with the year it is produced, and while some folks collect one from each year, one of that recent of production would not have increased in value at this point. Great knife though!
