I'm not sure what you mean by "Blade alignment to handle, But you should go to ABS main page and look under "Technigues" then "Master class" then "Knife Design concepts" Dan Petersen wrote this. You can get some good information by reading all of the Techniques!! I read them so I wont forget!!!

Centered in the handle material, with the "center line" of the handle being aligned with the "center line" of the blade. What that means is that if you sight down the "center line" of the handle (or the blade) the center of the handle SHOULD align with the center line of the blade..... whether that be sighting from the top or the bottom. If sighting from the handle end, the blade should look straight, and NOT angled to one side or the other.

Generally when a blade looks misaligned with the handle, its due to the maker grinder more off one side of the handle material versus the other side. Likewise, if it's a bare blade (one without a guard or handle installed) that appears to be "veering" off one way or the other, it's due to more material (steel) having been ground off one side (usually near the tip) then the other. In order to get it "right", you want to grind a bit off the side the blade is veering towards. I often tell students to look, twice as much as you grind. This means sighting down the length of a blade during grinding, and if you see the blade veering off, you need to grind a bit on the side it's veering towards, in order to bring it back to center.

This is also paramount when you install handle material and grind it down.... in my book, taping up a blade is a big "No-No", simply because you cannot accurately sight down the "center" of the knife/handle material combination to ensure you're keeping things centered.

There is no "magic formula" to it..... just concentrating, and taking the time and care throughout the entire process is how you "get it right".

It's not completely clear what you're asking. Ed covered the alignment well one way. It you are asking about the alignment the other then a lot of that is arbitrary but usually a hunter or Bowie has a handle that angles down slightly and a dagger or fighter has one more in line with the spine of the blade. Again, a lot of this is discretionary to the maker.

Hmm, really im asking about a blades blade geometry.

thank you for the information Master Ed.(saying with reverence given to a teacher.)
