We've told you before how to hone your own knives and why sharp knives are useful, but for a proper knife sharpening you need a professional. Our standard suggestion is to hit a local market or ask your friendly butcher, but we're impressed by the mobile knife-sharpening operation Danny at Gizmodo spotted outside our building.
Obviously, someone with a motorbike and a generator could cover a wide area, so we wouldn't be surprised to find similar operators at markets and other foodie-friendly locations. If you have a favourite knife-sharpening service, tell us about them in the comments.
