I got this as a gift from a relative. It was given to her by a chef. She said she isn’t a butcher (she is a pastry chef) and passed it on to me. She is Japanese and said it was a Chinese knife. It is a heavy and thick bone type cleaver that was sharp with pretty large burr on it. I am assuming it is carbon steel. I like it and would like to know a little bit more about it. Any help on ID and details of origin would be very much appreciated. Thank you KKF.
