Knife Center is in Fredericksburg, VA near me, right off Rt1, but they are not like Smokey Mountain Knife Works where they have big displays, although they do have a small display in the front lobby that is neat to look at, they are more of a warehouse for orders. I may be wrong since the last time I was over there, so give them a call. There is also a Gander Outdoors in Fredericksburg off Rt 3. Of course there is Bass Pro Shop in Ashland about 1/2 hour south of Fredericksburg off I95 south. I am sure there are others, or Cabelas, along your route. something more local is Greentop, more of a hunters store like Gander Outdoors, but they had a few knives. That is all I can think of in my neck of the woods in VA around I95. Hope it helps.
ps. In PA there is a knife store in Intercourse, Country Knives, kind of high prices but a very big selection. And do not forgot about GEC in Tidiote, PA, not sure if they have a showroom.
