I am going to use the Sheet Metal function in Solidworks which is something I haven't used before. It will have angled edges to the blade to deflect attacks, I just want to do it properly rather than fumbling it with other steps.
Even still, the bars are 10mm Titanium, the blade and supports are 5mm Ti and the bulkheads total 52mm in thickness. It wouldn't do it any good, probably twist the 5mm welded supports, but I doubt even NST could rip it off in one hit.
