I purchased this item for around 8,000 yen about a year ago and used it twice for splitting firewood during camping trips. The large blade and its thickness make it very powerful. After use, I cleaned it and applied camellia oil, so there appears to be no major dirt or rust. This is a used item, so please refrain from purchasing if you are looking for a pristine item. The following is a product description: A large yet exceptionally sharp forged carbon steel blade with a thickness of 5mm. Its weight allows for greater force with less effort when swinging it for splitting firewood, and the long, wide blade bites deeper into the wood. It has a surprisingly sharp edge for a thick-bladed hatchet. The forged carbon steel blade can effortlessly cut through thick magazines with a single draw. This hatchet has considerable cutting power just by swinging it. With this hatchet, you may not need a baton for the batoning method. If you are a man, you can split the wood by swinging the hatchet and letting it bite into the wood, then hitting the wood against the ground. This is a powerful, large hatchet with cutting power comparable to an axe. The full-tang construction, where the blade and handle are made in one piece, provides excellent durability. The natural wood handle has a luxurious feel and is well-made for long-term use. Total length: 328 mm Blade length: 200 mm Blade thickness: 5 mm Weight: Approximately 560g
