This longsword has been updated in several versions and is finally complete. We used heat-treated 65MN steel as the material for the blade, you can understand it as spring steel, which is what many pickup trucks use for shock absorption, it's more durable and tougher. You can easily make it bend 60° without deformation, and you can make it pass through paper, bottles, wooden boards, etc. without any problem. The design of the handle is the hardest part, you need to make sure that it is removable and at the same time you need to make it fit perfectly with no gaps. The removable design solves the idea of some people wanting to disassemble their swords and allows you to get a better understanding of the structure. You don't need to worry about the structural strength of the handle because it's right there in front of you and it's FULL TANG, we've gone through N number of tests without any breakage. Anyway, trust me, it's going to be a good choice for you, you can easily play it for a while, take it home now!
