Just because something is cool, doesn't mean that something is plausable.
Sure, when that guy got crushed in that movie by that slab of glass falling on him, that was COOL. Do you -REALLY- want it to happen, though? No. I'd rather not see a real life person crushed by a slab of glass and have his entrails all over the sidewalk, like, really.
But that's not the point.
I do agree that different types of weapons with different types of metals should be added, and they will be, at some point in time, don't you fret. However, I also feel that it will be a lot of work for the Resources Deparment to implement such a change, and it might take months before anything occours. It's taken months for me to even get close to finishing the vehicles into parts -planning- stage, and that's sad. There are so many things to balance, it's unreal.
And back to the naming of items. I just thought of something else. When you make the blade, you'll of course want to put a name on it, right? Something along those lines? Well, if you give the blade a name, and then add it to a hilt to make the sword, will the name appear on the sword? No, I don't think so. So, we'd be forced to have you name the sword when you place the objects in it for construction. Which means half of you will mess up and make the sword blade and hilt, then go to put it together and go 'Oh shit, I don't have a Chisel to name this sword', so you'll be forced to make a normal sword, which you already have 50 of.
Not that I CARE, if you screw up, that's your problem, surely not mine. But I'd rather not hear your whining about how it was planned out poorly, when you people just can't look ahead to see what you need

(I'm only joking around here, people.)
