Welcome! I have found no better place to learn able kitchen knives and most things kitchen related. Lot's of knowledgeable local Philly members on the forum!
Haven’t been, but I wish I could! I heard there used to be a sharpener in RTM … never went though. When I first saw a video of District Cutlery I thought, wait, which market is that? Turned out to be a few hundred miles off.
