The more I looked around for information on this, I think what I posted earlier is different from what you have. That post mentioned that the wrenches were -VV- wrenches made by Easco and yours is a -K- wrench made by SK.
I think what you have is a promotional item for the "Craftsman 1994 Racing Team" which was a racing fan membership program. I'm guessing that what you have is not part of any full set, but is a short run item connected to that promotion. Still interesting and collectable. (photos snagged from eBay)
Just my opinion.
