Received my new BK&T knife Monday seems very well made and sharp I think the handle is a little wide, at least for my hands. Yesterday I noticed the Kydex sheath is cracked (below where the cordura belt loop is attached to the Kydex), How can I repair this? What is the best (sanitary) way the clean the grease from the blade? I don't think i want this grease in contact with food. Thanks.
