I purchased this but never had a chance to use it, so it's been stored away. Although unused, there are some scratches on the carabiner. The following is quoted from the product page: ---------------------------------------------- A carefully crafted item created by the fourth-generation blacksmith of "Anyojiya," a blacksmith shop with a 150-year history. It inherits the techniques of Echizen Uchihamono (forged knives) and is a forged product made using traditional methods. This wedge is convenient for splitting small pieces of firewood and is recommended for those who don't want to carry a bladed tool. You can easily split firewood just by hitting the head. The tip and head are made of carbon steel S45C and are heat-treated, designed to withstand impact. Also, it is rust-resistant due to oil quenching coating, making maintenance easy. It comes with a carabiner for convenient carrying. 【About Maintenance】 It hardly rusts, so oiling is not necessary. If the blade edge is damaged by hitting a stone, etc., the ease of piercing will be restored by using a metal file. 【About Anyojiya】 The grandfather moved from Anyoji-cho, Echizen City, famous for Echizen Uchihamono, to this Ono City. We have been stubbornly adhering to the traditional manufacturing methods that have been passed down, and we have been in business for about 150 years. We are confident in our commitment to the product and its quality by consistently producing from forging to finishing. ※Images are for illustrative purposes. ※Because each one is handmade, there may be slight variations in size, thickness, and weight. ※Laser cutting marks will remain on the sides. ※Black skin of the metal may remain on the body. ※The color of the carabiner may differ from the image. ※There is a risk of some deformation if the head is hit hard with a heavy hammer. ※Dimensions are approximate.
