This is the first time I’ve used Knifeaid. I sent in eleven knives. They were everything from inexpensive paring and carving knives to high end chef and Japanese knives. The service is impressive. It’s very easy to wrap them up to mail. They send you the envelope and knife guards and great instructions. It only took about ten days and they were back. Impressive edges. I was worried about potential scratches, but they were perfect. I would recommend this service to all cooks. They brought back edges on knives that haven’t been this sharp in a while, if ever.
