Your knives are called the Collector Series and they are based on the Blackie Collins designs of the 70's. The artwork was contracted to Carolina Knife Company but I think Dillingham Graphics actually did the blades. Not that many around as the project, which was planned to be 1000 sets, was never completed.

If you have the folder with the graphics, it is one of very few prototypes that were never offered for sale.

Very nice knives and a great addition to the "other than guns stuff" most of us S&W collectors have.
