there's 202 knives in Chadd's Ford. It's a bit of a detour but if you take 202 south from RT 30 you will find it. They have a collection of antique knives, a few consignment items and a boat load of cheapies and knockoffs. If you like slip joints or fixed blades it's your place however if you are looking for the latest benchmade or spyderco he will have to order it. Bring cash, they don't take credit cards or checks.

Country Knives is fantastic for modern production knives. You will pay close to MSRP there but you can play with just about any knife made within the last 5 years. I have been meaning to take a trip back out there one of these days.
