The blade steel is made from 1095 high carbon and 9260 spring steel, I’ve had it for almost a week it it is a amazing katana, I’ve done a lot ot cutting with it and it cuts amazing stays very sharp and it super durable, the handle looks amazing I had it switched to a burgundy and it looks amazing it’s very tight and hasn’t loosened and the sageo on the saya looks amazing and is tied very well, the sword amazing and is definitely built to last and great for high performance cutting and supper quality, my only slight complaint it that the paint in my saya had had a small chip in the paint in my saya when I first got it that been slowly chipping more but I reached out the the support team don they are taking care of it for me, I defiantly recommend swordis and any katana if there aight there support team is amazing and the katanas and the best quality
