This is a set of Aquatiic Ice spoons and forks from Yamazaki Kinzoku Kogyo. The purchase price was about 6,000 yen each. I bought them about a month ago, but I haven't used them much because they are a bit heavy, so I would like to sell them. Yamazaki Kinzoku Kogyo is a trusted brand, having been used at the Nobel Prize banquet. I think the eating edge is smoother than general cutlery. Thank you.
