For a given thickness of plywood, say 1/2 inch, I know that you can get variations of plywood with different number of plys. Sheathing is usually 3 ply, popular or birch plywood is 5 ply, and I have seen 7 ply.

So, if you were to build a cabinet for the shop, would you be concerned about the number of plys?

Does more plys increase the strength noticeable?

Thanks in Advance,
