Hello there dear Community, my friend and I have been talking about the Difference in Alignment and Auto Alignment when it comes to the sword edge.
Here is the Question though: What is the Generally Agreed on Definition of edge alignment?

Lowest offset of blade direction from swing direction. Skallagrims video
He also has some vids about auto alignment. IMHO most Auto Alignment tests are wrong and only show that the cross section of the grip rolls one way or the other, you would need to suspend the blade in the air to get real measurements of the blade itself.

There's no auto edge alignment. That's the end of the topic.

Automatic edge alignment. A myth why Katanas (or curved blades in general) are better because they give you the right edge alignment by their geometry somehow without you having to do anything. At least that's my understanding of it. There are reddit wars fought over it. OP might just be here to start another.

That doesn't make sense.. the slightest movement of the practitioners wrists, arms, shoulders or body will change blade alignment mid cut...and there is only ONE correct, optimal angle of attack for a blade into any target.

I know, no such thing exists. I hadn’t thought about trolling at this point.

Maybe there is a hidden feature, like autocorrect on the phone. *You said "Kill guy in front", did you mean "Kill my friend"?* Maybe it is responsible for every miss or botched cut and has been installed on swords to make them less dangerous?

In case of bad edge alignment press "auto" !

"Ah crap, where is the auto button again. Oops, thats not it." "Man, why are you squatting down?"

(The Stripling butts in on the adult conversation)
My understanding is that--at least with a saber or simulacrum--because the COG leads the COP by a wider margin than a straight blade, a greater percentage of blade mass is already past the point of contact, at impact. With a straight blade, you must work to get your hand (and subsequently the COG) in front of the impact point, to avoid "batting" the target at a 90 degree angle to the blade. If you don't get your hands out in front, your blade mass will only reinforce the direction your edge is already going, rather than pulling it back into the large-muscle swing plane.
Of course, if you're really good, you won't lose any momentum in blade--well, not "correction", but "re-direction"--and subsequently you'll hit just as hard, and parry--this is kinda important--a few milliseconds sooner.
NOT trying to cause a ruckus; I'm open to edification.
On a tangental, but related topic: I'm waiting for the day they start making curved golf clubs. I suspect the pros won't swap out their straight sticks for curved. Duffers like me will, and the difference between will considerably narrow. The pros will always win, though, dangnabit!

Dear glendon,
Your explanation seems to conflate two different issues. A straightforward reading suggests that the first two sentences are about slicing cuts vs. hewing cuts. The third sentence seems as though it could be about edge alignment, but has no support from the previous sentences and isn't very clear itself. Try visualizing the actions described or describing them in more detail, and you'll see what I mean.
Best,
Mark Millman

In some circles, it is believed a curved sword, particularly a two-handed curved sword such as the katana, presents easier edge alignment over a straight sword. There are a few ideas why, but the overall consensus suggests the curve makes the tip trail in such a way that the edge remains more in line with the arc of the swing for longer.
Or something.
It's just body mechanics and practice, really.

I'll take my lumps: That's a pretty sloppy statement--even allowing for the 5 IPAs. Well, 3.5, at the time of posting. My logics professor at Kent State would have been appalled. With luck, my gist will be enough to generate thought, even if its negatively pointed at me. That's the humorously-expressed caveat in parentheses, up there. Starting out. At the front. Setting the tone. Keeping it less-than-scholarly. My psych mentors, however, would have me consider how you personally perceive your public critique of my (il)logic as furthering the general conversation--and I do. Try contextualizing this forum as a medium consisting of something more than a mere vehicle with which to display your particular form of genius, and you'll see what I mean.

I salute your 5 IPAs......especially if they were DIPA's.....

It's just body mechanics and practice, really. I can tell you that it doesn't. If it does, no JSA practitioners would have bent their blade in their cuts. Ever. The more curved the blade is, the more tendency it will twist itself out of the correct blade alignment and screw you up, since more mass is out of your grip's axis and it will rotate more likely inside your grip. I don't teach for free so I'll stop here.

Also possible OP isn't trolling because I remember Mini Katana is happy to perpetuate the auto alignment myth in their TikTok marketing. OP might have seen those. We've already weathered decades of silly katana myths, we just gotta keep chugging along!

Auto alignment is being ridiculed, because it does not exist as such. That's all. My guess it's being told by people who know nothing to people who know less or by trolls (and, of course, to sell stuff). Like the oldy "Katana cuts steel". No it doesn't. So discussion doesn't make much sense unfortunately.
Some swords are harder to index than others, some people have easier times with one shape over the other, but none will "just do it" by itself....
