<Snipped quote by Nimda>
If shinji used his sword all his life like I suspect, then he'd notice even if you or I wouldn't, and that would affect him physically, with an unnoticeable change from his muscle memory, and it would affect him mentally, both due to noticing the change, and from lack of familiarity/trust.
To try an example, think of your keyboard being suddenly replaced with one that has the F and J ridges removed and new ones on [, x, /, and 5. It would change your efficiency, even though it's "the same". And with a weapon, especially in real combat, those things are pronounced because you are in serious danger if you make an even 0.00000001% less than perfect action/reaction (in combat) or a simple mistake just due to the nature of weapons. Maybe the physical aspect is only 0.000000000000000000001% different in the weapon and 0.0000000001% different in the user's body, but .0000000010000000000001% plus the multiple mental differences can reach 0.00000001% very quickly and very easily.
And this is all assuming that you can match the mass perfectly even in a new shape, AND remove the air resistance difference from both the different shapes and from the blunt vs sharp.
We can go physics all day, and you'll probably win on it because you're more motivated to seek out the info you need to, and we can go psychology all day, and I'll probably win on it because I'm more motivated in most context, but unlike the psych and similar situations in history, the physics are hypothetical at best at this time, and I will contest your math working the way you say when translated to 4d indefinitely.
Is that a satisfactory "What are you talking about?"
Sorry, mindset currently similar to how Left was. Part of me thinks and hopes it's an "echo" of sorts, but that's off topic.
Again, that was never my point to begin with.
I don't use the ridges, so I doubt it would change anything.
Skip.
I'm not using confirmation bias. I'm simply arguing that they'd behave the same way, proven in physics. If you want to discuss it psychologically, I agree with you. You don't fight the same way.
I suppose.
They'll probably come back.
