I don't think I'd be very good for wearing a suit that heavy with the restricted movement it would provide. At least with modern armoring for front-line soldiers, what they wear is designed to still allow for a high amount of mobility for the amount of weight and protection being added. That, and with the weight being compared between full tactical gear with weaponry(for the modern soldier) and simply the weight of the armor itself(for the knight), I'd still say it's beefy. Add on the 12-14lb shield(6-7kg), and then a sword(4lb) or mace(6lb), and you're simply making more weight for a man to move with.
I'm actually planning my next piece(which is so much more complex that it's honestly a bit disgusting[combination of complex design+complex weave+scalemail portions+5 different metals]) which will include titanium and aluminum. I wouldn't say the next one will be as structurally strong as the one I've made here(since this one is all steel), but it'll look so much better. It's going to be an elven style set of armor, and very, very fancy-looking, but that's a project that will likely span the next 5 or so years, on and off.
As for the construction of what I have now, it's simple butted steel. I plan on eventually going through and spot welding the rings shut(because I do not relish the idea of riveting it), but beyond that, it's essentially complete. In regards to me bearing a sword, I don't have one of my own yet, or, rather, not one that I can call my own truly. When i get one made for myself, then I'll bear it accordingly, but until then, I either won't bear one, or I'll bear mock pieces for the aesthetic.
And I am military, so i would certainly hope I'm better off than a couch potato.
And Tiko, I didn't say it made you sterile. Other women, sure. And I simply have to assume that Dash was either super drunk or only semi-conscious.
