Low Tech Rules with High/Ultra Tech

[Koningkrush]

I frequently use the blunt trauma and edged weapons rule for low tech meaning you need double DR to actually cut into flesh (otherwise damage is crushing). However, I was wondering if this rule still works at a higher Tech Level?
Would a 40/20* monocrys suit require a whopping 81 damage before the damage is cutting? It seems a bit extreme to me, but maybe the armor really is that difficult to actually pierce, although the person in side would probably be smashed into oblivion like a crushed grape before his suit was eventually cut into.
