Recieved a soft blue Aiiwatani and a hard Shobu from this batch. The Aiiwatani is the perfect Kasumi killer on the go. Absolutely love it! The Shobu is pretty hard and a great shape for finishing edges and Uraoshi sharpening at work. Highly recommended! Great customer service/communication as always!
