Knife sharpening north of the Loop. You need this!.
You can get dull knives reconditioned here for about $5 per blade. There's usually a wait of a few days but they'll do it immediately if they're free. Very useful service, especially if you cook a lot. You can also buy new or reconditioned knives here (and also barber's supplies!). Amiable staff here. Go out and support a worthy local business!
