The C-712 is more heavily armored and heavily armed
and looks slightly different
I actually made the C712 first on accident when using reference pictures to make them
(little rectangular things on the front)
and when I got a better reference Image I noticed that it was different
so I checked the halo wikia page on the longsword and found out the first thing I looked at was a variant of the longsword called the C-712 longsword
