To forge a single component for every item he wanted to make, he would need to put in a lot of effort.
The casing, the individual parts, everything required him to put in his best efforts. However, he had the system to rely on. All he needed to do was ask it for help, and it gave him a complete rundown on how to move forward.
The fact that he could also directly influence the material without having to worry about making direct contact with the material was very good as well. However, thanks to the high density of metal elements in the refined metal, he couldn't control it on a structural level.
As such, he had to resort to hammering, folding, and chiseling for the components that required much detail.
The casing was not meant to be very big. It was egg-shaped and would contain all the other parts and constituents. It was smaller than a palm and about three fingers wide.
