The square will only be accurate for a given distance. There is NO

If the blade is strait and it is out of square at any distance, it is out of
square at all distances. It just becomes more obvious at longer distances.

I make things square for MY projects...usually spanning 8 to 12 ft.
And I've built some wooden, quick squares precisely for this...2', 4',
6' in length, etc. These are dead-on...for my uses.

If you set up a square...and draw a line 10,000 miles long...lol...its
not gonna be square at the end of that line. But it may be perfectly
square at 4 ft. So its also relative.

No it won't. See above.

IMHO, a combo square is one of the least accurate tools you can buy.
I've never seen one yet that doesn't have at least a little play in
them.

Quit buying those Chinese squares. Try a Starrett or Mititoyo. You'll change
your mind.
