There's also a Chesapeake Knife and Tool in Whiteflint Mall, and it's on the Metro red line (While Flint Metro stop). If you have a vehicle, there's Knife Center of the Internet in Beltsville. Not sure if Howard Korn carries any customs. You might want to check the website to see.
The best stores are either up in Frederick (on Market street) or just south of Baltimore (A.M.H. Cutlery). I haven't been to the Frederick store (don't remember the name).
Here is the only particular I have at hand:
Rob
A.M.H. Cutlery
701 Evelyn Avenue
Linthicum, MD 21090
M-F 12-6, 410-636-0880 (a call first is highly recommended)
Rob's dad, Hoag, is a real old time knife guy and it's worth the trip up there just to talk to Hoag. It's a little hard to find and they don't keep strict hours (they spend a lot of time traveling around to knife shows).
