From the whole basic structure of the blade, Eisen wasn't actually sure if this would be a viable shape for a weapon, considering that it seemed a bit easy to bend or break if it was a heavy weapon with thin parts like that.
But considering that this was a world where it was possible to magically harden things with mana, it would most likely work out as long as Eisen chose the materials and processes right.
First things first, Eisen started to heat up all of the steel that he needed for this blade. Once the ingots were glowing in a bright yellow light, he started to fold them into each other while pouring mana out through his hammer into them, like he usually did, and then started to form the large lump of steel into the right form for what he wanted to make.
