Type: Knife Material: Copper Use: Butter knife This original pure copper product is made robustly through thousands of hammer strikes. This time, we have created a new, medium-sized knife, 15.0 cm long. It's a spoon that melts hard butter from the refrigerator with the temperature of the knife and the warmth of your hand, allowing you to scoop the right amount. Also, when spreading, you can use the flat surface on the back to spread the softened butter. If the butter is hard, the bread will crumble, but with this knife, it's a wonder! You can spread it beautifully... Please do it slowly. This is a technique that can only be achieved because it is not commercially available and is made in a small workshop. Pure copper, with a purity of 99.9% or more, has twice the thermal conductivity of aluminum, five times that of iron, and a whopping 25 times that of stainless steel. The photo shows ice taken straight from the refrigerator being cut smoothly in a few seconds. We have posted this because we received a comment from a customer who couldn't believe it. Please try it. Returns are accepted if it doesn't cut. The surface is fully hammered, creating a unique and beautiful pattern. Also, the knife part has a serrated edge and is slightly curved to make it easier to cut butter. The handle is designed to be easy for anyone to hold and to convey the warmth of the hand. The length is 150 mm, a convenient and easy-to-use size. It can also be used for margarine, jam, basil paste, etc. Please do not leave it in the container. The hammered surface and back are finished with a glossy tin plating, which is also used for tableware, providing a smooth feel and making it resistant to oxidation. It will continue to shine beautifully for a long time. Copper and tin are essential metals for the human body and have bactericidal and sterilizing effects, which are also beneficial for health. In particular, the effect of eliminating the new type of epidemic has been confirmed, and it is a product that we want everyone to use. Due to being handmade, please understand that no cancellations or returns are accepted. Also, the number of pieces that can be made is small, but we are exhibiting several types of works. Please take a look at our other exhibits. (Average size 150x23x10mm, oxygen-free copper plate thickness: 2.0mm, 45.3g) 《Reference》Here are some opinions from customers who have used it. Since then, I have been using it almost every day. It cuts butter nicely and feels great. Thank you very much.
