Slippies near Philadelphia?

[puukkoman]

Hey everybody.
I've recently moved to Philly, and am wondering if anyone can point me in the direction of a shop, store, etc. that has a decent selection of slipjoints?
Any nearby antique shops you'd recommend? Any knife/gun stores with a nice knife case and a friendly face behind the counter?
Thanks...

Country Knives in Lancaster, prices are above MSRP on a lot of things. King of Prussia has a gun show about every month. Various flea markets.
